1. Introduction

Cistanche deserticola Y. C. Ma, a perennial parasitic herb from the Orobanchaceae family, mainly parasitizes the root systems of Chenopodiaceae plants such as Haloxylon ammodendron and Haloxylon persicum growing in desert regions. Lacking independent photosynthetic capacity, the herb fully absorbs water and nutrients from its host, restricting its natural habitats to arid and semi-arid northwest China, including western Inner Mongolia, Xinjiang, Gansu, Ningxia, Qinghai and other desert and Gobi terrains [1].

Five species of the genus Cistanche are distributed across China. Among them, four varieties possess medicinal and edible development value: Cistanche deserticola Y. C. Ma, C. tubulosa (Schenk) R. Wight, C. salsa (C. A. Mey.) G. Beck and C. sinensis G. Beck. Table 1 summarizes the primary species, host plants and geographical distribution of Cistanche.

Recorded as a top-grade medicinal herb in Shennong's Classic of Materia Medica, the earliest Chinese herbal monograph, Cistanche deserticola boasts a thousands-year-long application history in traditional Chinese medicine (TCM). Ancient records document its therapeutic efficacy: "Treats five consumptions and seven injuries, tonifies the middle energizer, relieves cold and heat pain in the genital tract, nourishes five internal organs, strengthens kidney essence, boosts fertility, and eliminates abdominal masses in women" [2].

TCM theory defines Cistanche deserticola as warm, sweet and salty in nature, acting on the kidney and large intestine meridians. It warms kidney yang, nourishes essence and moisturizes intestines to relieve constipation. Clinically, it addresses impotence, infertility, cold lumbus and knee pain caused by kidney yang deficiency, as well as dry intestinal constipation triggered by essence and blood depletion. Known as "Ginseng of the Desert" for its mild tonifying property (warm without dryness, nourishing without excess), it occupies a core position among tonic herbal medicines.

According to the Catalogue of Substances Both Used as Food and Medicine per Traditional Usage released by China's National Health Commission in 2023, Cistanche deserticola is the sole Cistanche species officially categorized as medicinal-edible homologous raw material. This policy breakthrough not only inherits its traditional medicinal value but also unlocks huge market potential in functional foods, nutritional supplements and broader wellness industries, aligning with modern preventive healthcare concepts for chronic disease intervention.

Modern phytochemical research confirms that Cistanche deserticola contains abundant bioactive compounds, primarily phenylethanoid glycosides, iridoids, lignans, polysaccharides, amino acids and flavonoids [3]. Phenylethanoid glycosides have long been the mainstream research focus due to their potent antioxidant and neuroprotective effects. Nevertheless, Cistanche deserticola polysaccharides, another high-content ingredient with diverse biological functions, have gained surging research momentum in recent decades. Massive in vitro and in vivo trials validate wide-ranging Cistanche deserticola polysaccharides benefits covering immune balance, anti-aging, neuroprotection and gut microbiota regulation.

This review systematically sorts out the extraction and purification techniques, structural features, biological activity mechanisms of Cistanche deserticola polysaccharides, analyzes core bottlenecks in current research, and puts forward scientific outlooks on its industrial development. It intends to provide clear theoretical basis and operational guidance for deep research and high-value comprehensive utilization of Cistanche deserticola polysaccharides.

2. Extraction, Separation and Purification of Cistanche Deserticola Polysaccharides

Cistanche deserticola polysaccharides (CDP) are characterized by complex branched structures, broad molecular weight distribution and excellent water solubility. Different Cistanche varieties differ drastically in cellular tissue structure, polysaccharide content and hydrophilicity, leading to distinct extraction parameters and final yields. Extraction efficiency and natural structural integrity are entirely determined by separation and purification workflows, while molecular weight and monosaccharide composition directly dominate Cistanche deserticola polysaccharides benefits.

2.1 Extraction Technologies of CDP

Traditional extraction methods rely on solvent leaching, mainly hot water extraction and alkaline extraction [4]. Benefiting from innovations in natural product separation technology, modern auxiliary extraction approaches have been integrated into conventional workflows, including microwave-ultrasonic synergistic extraction [5], single ultrasonic-assisted extraction [6], microwave-assisted extraction [7] and compound enzymatic extraction [8]. Different extraction protocols deliver variable CDP yields and purity, with optimized crafts capable of preserving native molecular conformation and biological activity to the maximum extent.

Hot water extraction remains the most widely adopted industrial method. It breaks plant cell walls via high-temperature water to dissolve intracellular polysaccharides into aqueous solution, featuring simple operation, low equipment investment and mild reaction conditions. Sui et al. [9] adopted 90 °C water bath extraction for 4 hours and obtained CDP composed of glucose, galactose, rhamnose, arabinose and fructose with an average molecular weight of 385 kDa. Wu et al. [10] also utilized hot water reflux to isolate CDP mainly containing arabinose, galactose and glucose, with trace rhamnose and mannose, averaging 561 kDa molecular weight.

Alkaline extraction can recover CDP from cistanche biomass yet suffers from low recovery rate, high residual protein impurities and irreversible destruction of polysaccharide glycosidic linkages. CDP yield is highly sensitive to extraction temperature, duration and solid-liquid ratio. Aladan Mamatali et al. [11] optimized extraction parameters for C. tubulosa polysaccharides, identifying optimal conditions: 90 °C extraction temperature, solid-liquid ratio 1:50 (g/mL), 2-hour extraction duration, achieving a 5.76% polysaccharide extraction rate.

Though traditional hot water extraction preserves crude polysaccharide native chemical composition, it has obvious drawbacks: prolonged heating time causes polysaccharide browning, simultaneous dissolution of miscellaneous water-soluble substances reduces purity, and overall extraction efficiency is limited.

To address these limitations, researchers have developed composite auxiliary extraction technologies. Yang et al. [12] optimized enzyme compound ratio and ultrasonic parameters, boosting CDP yield by 1.33 times versus traditional hot water methods. Li Shenheng [13] compared multiple extraction crafts and confirmed ultrasonic-assisted extraction delivers the highest polysaccharide recovery rate and antioxidant activity of extracts. Emerging technologies including flash extraction and surfactant-aided extraction have also been applied for CDP preparation. Response surface methodology research on flash extraction indicated a maximum polysaccharide yield of 12.35% under conditions: solid-liquid ratio 1:53 g/mL, rotation speed 5,387 r/min, 1-minute extraction time.

Our Factory Processing Superiority: Our production line adopts integrated ultrasonic-enzymatic synergistic continuous extraction for C. tubulosa. This green composite craft shortens extraction time, avoids long-term high-temperature degradation of polysaccharide chains, increases total CDP yield far above conventional hot water processing, and fully retains complete polysaccharide molecular structures to guarantee full-spectrum Cistanche deserticola polysaccharides benefits for downstream product formulation.

2.2 Separation and Purification of CDP

Crude polysaccharides acquired after primary extraction contain abundant impurities. Purification aims to remove pigments, proteins, lipids and small molecule heterologous substances to obtain homogeneous CDP fractions for subsequent structural identification and activity verification. Standard purification pipelines include degreasing, decolorization, deproteinization and alcohol precipitation, separating target polysaccharides based on molecular size, polarity and charge properties to acquire low-dispersity uniform polysaccharide components ideal for functional research [14].

DEAE cellulose ion exchange chromatography serves as the mainstream purification medium for CDP. It efficiently separates neutral/acidic polysaccharides, proteins and nucleic acids with stable adsorption performance, fast elution speed and outstanding resolution. Standard purification workflow: raw material degreasing, hot water reflux extraction, ethanol precipitation, Sevag method deproteinization, followed by DEAE-Sephadex A-50 ion exchange chromatography and Sephacryl S-200 gel filtration to obtain highly purified CDP, which is further characterized via infrared and ultraviolet spectroscopy [15].

Table 2 summarizes mainstream extraction & purification technologies, structural characterization tools, molecular weight ranges and monosaccharide profiles of CDP reported in recent studies. These structural diversities lay the material foundation for the versatile Cistanche deserticola polysaccharides benefits observed in pharmacological trials.

2.3 Structural Characteristics of CDP

CDP belongs to heterogeneous polysaccharides with highly diversified backbone structures, dominated by neutral arabinogalactan (AG) and acidic rhamnogalacturonan I (RG-I), plus minor fructan fragments. Most sugar units are α-pyranose linked via 1,4- and 1,6-glycosidic bonds, with molecular weight ranging from 10⁴ to 10⁶ Da and weight-average molecular weight (Mw) distributed between 300–600 kDa. Acidic CDP contains galacturonic acid (GalA) and glucuronic acid (GlcA), with uronic acid content reaching 8%–15%, bringing negative electrical charge and stronger immune-regulating Cistanche deserticola polysaccharides benefits.

Crucially, origin, harvest season and processing methods (wine steaming, direct steaming) significantly alter CDP molecular weight and monosaccharide composition [13], leading to inconsistent activity performance across raw material sources. The schematic molecular structure of typical CDP is shown in Figure 1.

3. Biological Activities and Functional Mechanisms of Cistanche Deserticola Polysaccharides

As core bioactive ingredients of Cistanche, CDP exhibits prominent pharmacological effects covering immune regulation, anti-oxidation & anti-aging, neuroprotection, intestinal flora modulation, hepatoprotection, anti-tumor and anti-osteoporosis. In vitro cellular assays and in vivo animal models consistently prove CDP features excellent biocompatibility and low systemic toxicity, exerting synergistic multi-target, multi-pathway regulatory effects-especially unique modulatory capacity via the gut-brain axis and gut-liver axis. Core research findings are organized in Table 3 and Figure 2.

3.1 Bidirectional Immune Modulation

Immune regulation is the most extensively studied of all Cistanche deserticola polysaccharides benefits. CDP delivers bidirectional immune balancing effects, restoring normal immune function under hyperactive or immunosuppressed conditions [49]. Mechanisms include promoting lymphocyte proliferation, activating innate immune cells, enhancing phagocytosis and cytokine secretion of RAW264.7 macrophages (illustrated in Figure 3) [50].

Lymphocyte proliferation is a marker of non-specific cellular immunity. Wu et al. [10] verified CDP stimulates mouse lymphocyte proliferation in a dose-dependent manner. Yao Jinqian et al. [24] demonstrated CDP balances T cell subsets, elevates IL-2 secretion to boost immunity and suppresses excessive IL-6 release to alleviate pulmonary inflammation. Zhang et al. [25] confirmed water-soluble CDP accelerates maturation and functional activation of mouse bone marrow dendritic cells through the TLR4 signaling pathway. Feng et al. [51] further illustrated CDP triggers dendritic cell activation via TLR2/TLR4-mediated MAPK and NF-κB cascades, amplifying humoral and cellular immune responses, validating CDP as a safe, natural plant-derived vaccine adjuvant [52].

CDP activates RAW264.7 macrophages to boost NO release, upregulate TNF-α and IL-6 expression, increase phosphorylation of IKKβ, IκBα and NF-κB p65, and strengthen cellular phagocytosis via NF-κB pathway activation [26]. Additional research reports CDP polarizes tumor-associated macrophages from pro-tumor M2 phenotype to anti-tumor M1 phenotype [27]. Zhang Tao et al. [28] also verified CDP enhances phagocytosis and cytokine release of THP-1 monocytes to mediate immune homeostasis.

3.2 Antioxidation and Anti-Aging Effects

Oxidative stress is the core driver of bodily senescence and degenerative disorders. Powerful antioxidant capacity endows CDP remarkable anti-aging Cistanche deserticola polysaccharides benefits [53,54]. Dual-action mechanisms include direct free radical scavenging and indirect modulation of antioxidant signaling pathways to delay cellular and organismal aging [55].

In vitro trials show CDP improves proliferative capacity of senescent fibroblasts, reduces positive senescence-associated β-galactosidase cells [32], and eliminates intracellular ROS through activating the NRF2/HO-1 antioxidant pathway [33]. In premature ovarian failure (POF) animal models established by Qiu et al. [36], CDP maintains stemness and facilitates differentiation of female germline stem cells via the BMP4/SMAD1/5/9 signaling cascade.

Mitochondria are the primary source of intracellular reactive oxygen species. In D-galactose induced aging rat models, Xu Hui et al. [37] found CDP elevates hepatic Ca²⁺-ATPase activity, improves liver mitochondrial membrane fluidity and respiratory chain complex activity, while lowering hepatic mitochondrial MDA concentration and PLA2 activity to mitigate oxidative mitochondrial damage.

Declined anti-fatigue performance is a typical aging symptom; serum urea, lactic acid, hepatic and muscle glycogen serve as key fatigue biomarkers [56,57]. Yan Lei et al. [38] proved CDP extends exercise endurance in aging mice, reduces serum urea and lactic acid accumulation, and elevates glycogen storage in liver and muscle tissue.

Concurrent degenerative lesions occur in respiratory tissues alongside systemic aging. Sun Yun et al. [34,40] reported CDP significantly increases SOD activity in serum and lung tissue, reduces nitric oxide levels, inhibits pulmonary cell apoptosis, elevates collagen content and decreases elastin deposition in aging mice, delivering protective and repairing effects on lung parenchyma. Fang et al. [58] also validated CDP activates antioxidant defense systems in Caenorhabditis elegans, improving locomotor function and slowing senescence progression.

3.3 Neuroprotective Activity

While phenylethanoid glycosides were long recognized as primary neuroactive components [59,60], emerging research highlights outstanding neuroprotective Cistanche deserticola polysaccharides benefits, especially in Alzheimer's disease (AD) and Parkinson's disease (PD) animal models. CDP protects neurons and ameliorates cognitive impairment through multi-target mechanisms: anti-oxidation, anti-apoptosis, gut microbiota remodeling and signal pathway regulation.

In vivo studies confirm CDP alleviates cognitive dysfunction in APP/PS1 transgenic AD mice and D-galactose aging mice, inhibits cerebral Aβ plaque deposition and abnormal Tau protein hyperphosphorylation, and reshapes gut microbiota and amino acid metabolic profiles [61,62]. CDP suppresses neuroinflammation and shields neurons by modulating TLR4 and NF-κB signaling axes [25,51].

Sun et al. [63] and Yin Gang et al. [64] reported CDP elevates AChE and ChAT activity in cerebral cortex and hippocampus of AD rats, shortens water maze escape latency and improves learning and memory capacity [41]. Xing Haiyan et al. [35] confirmed direct protective effects on senescent nerve cells via NRF2 antioxidant, anti-apoptosis and cAMP/PKA/CREB signal upregulation. Yin Ruoxi et al. [65] demonstrated CDP upregulates SYP and GAP-43 expression in scopolamine-induced memory impairment mice, restores synaptic quantity and plasticity to reverse cognitive deficits. CDP reduces neuronal apoptosis, increases anti-apoptotic Bcl-2 expression and enhances DNA damage repair in aging brain tissue [39].

Jiang et al. [66] reported CDP improves cerebral antioxidant capacity by raising SOD and GSH levels while lowering MDA content. For PD rat models, Yin Shuailing et al. [43] found CDP activates the Wnt/β-catenin pathway and inhibits GSK-3β activity to protect dopaminergic neurons. Additional neuroprotective effects include alleviating spinal cord injury via suppressing NLRP3 inflammasome activation [67] and promoting neurovascular regeneration and neurological recovery in MCAO/R stroke rats through the Nrf2/Keap-1 pathway [68].

3.4 Intestinal Microbiota Regulation

CDP optimizes intestinal microecological balance by remodeling flora composition, reinforcing intestinal mucosal barrier integrity and suppressing inflammatory response, alongside positive regulation of gut microbial metabolites [69]. Oral CDP strengthens intestinal tight junctions, enriches beneficial genera including Prevotellaceae UCG-001, Odoribacter, Clostridiales vadin BB60 group, Alistipes and Lactobacillaceae, while reducing pathogenic Parabacteroides and Proteobacteria abundance and stimulating short-chain fatty acid (SCFA) biosynthesis [70,71].

Lian et al. [72] compared raw and processed CDP, discovering both alleviate antibiotic-induced gut dysbiosis and boost in vivo absorption of echinacoside, with processed CDP showing superior flora-regulating potency to promote proliferation of beneficial microbes and nutrient uptake. CDP also protects colonic myenteric plexus mitochondrial function against oxidative damage [66].

Inflammatory bowel disease (IBD) is closely associated with gut flora imbalance. Qiao et al. [73] evaluated CDP therapeutic potential for IBD: CDP downregulates pro-inflammatory IL-6, IL-1β, TNF-α and MPO activity, elevates anti-inflammatory IL-10 in colon tissue, suppresses SRC/EGFR/PI3K/AKT signaling and reduces pathogenic microbial diversity and abundance. Ma Guangli et al. [74] further revealed CDP treats ulcerative colitis via inhibiting NLRP3/GSDMD pyroptosis pathways.

CDP prevents alcoholic fatty liver by modulating lipid metabolism, enriching SCFA-producing bacteria, activating AMPK signaling to accelerate fatty acid β-oxidation and restrict lipid synthesis [75]. Multiple studies confirm CDP reverses antibiotic-triggered gut dysbiosis [76]. Wang Xiaoqin et al. [77] verified CDP exerts broad-spectrum antibacterial activity against Escherichia coli, Tetracoccus, Bacillus subtilis, with stronger inhibitory effects on bacteria than fungi such as Saccharomyces cerevisiae and Penicillium citrinum.

3.5 Hepatoprotective Effects

CDP possesses potent liver-protective Cistanche deserticola polysaccharides benefits [78]. In CCl₄-induced acute liver injury mice, CDP reduces hepatic MDA levels, elevates antioxidant SOD activity, alleviates lipid peroxidation damage and preserves hepatocellular membrane integrity [48].

From a gut-liver axis perspective, Wang et al. [79] explored CDP's protective effects against alcoholic liver disease: CDP improves intestinal permeability, upregulates tight junction protein expression, lowers serum ALT/AST and hepatic pro-inflammatory cytokines, enhances liver antioxidant enzymes and activates Nrf2 antioxidant signaling by inhibiting Keap1 expression. 16S rDNA sequencing confirmed CDP restores balanced gut microbiota composition in alcohol-damaged mice. Guo et al. [78] also validated CDP reduces hepatic MDA and triglyceride levels and modulates metabolic enzyme activity to mitigate chronic alcohol-induced liver damage.

3.6 Anti-Tumor Activity

CDP delivers anti-tumor effects indirectly through immune system modulation and tumor cell signal pathway interference, rather than direct cytotoxicity against cancer cells. Trials demonstrate CDP elevates natural killer cell activity and IL-2 concentrations, suppressing tumor growth in Lewis lung carcinoma and S180 sarcoma mouse models [80].

Xing et al. [81] reported CDP inhibits proliferation, colony formation, migration and invasion of A549 non-small cell lung cancer cells and induces tumor cell apoptosis by regulating ERK signaling and downregulating LINC01410 mRNA expression [82]. Cui Yongsheng [83] clarified CDP mediates anti-tumor activity by reprogramming tumor-associated macrophage polarization, confirming its immunomodulatory anti-cancer mechanism without direct toxicity to healthy cells.

3.7 Other Biological Functions

Beyond the above core activities, CDP delivers multiple supplementary Cistanche deserticola polysaccharides benefits including anti-osteoporosis, anti-depression, anti-glycation, UV photodamage protection, anti-radiation and wound healing promotion.

Wang et al. [45] confirmed CDP prevents osteoporosis via activating the Wnt/β-catenin pathway. Gu et al. [44] illustrated CDP alleviates postmenopausal osteoporosis inflammation by regulating the gut microbiota-SCFA-Th17/Treg axis. Song et al. [84] found CDP suppresses osteoclast formation and bone resorption through inhibiting RANKL signaling and ROS generation.

Multi-omics research by Liu et al. [85] uncovered CDP anti-depression effects mediated by gut homeostasis and microbiome-metabolite interactions. Liu Yuanyuan et al. [86] validated CDP protects HaCaT keratinocytes and mouse skin against acute UVB photodamage. Gao Hui et al. [87] reported appropriate CDP concentrations stimulate human fibroblast proliferation to accelerate wound tissue repair. Additional research proves CDP relieves menopausal symptoms by regulating hypothalamic-pituitary-ovarian axis function, correcting neurotransmitter imbalance, stabilizing endocrine secretion and boosting systemic metabolism [88].
