Weight, hard texture, slightly flexible, not easy to break, brown cross-section, with light brown dotted vascular bundles arranged in wavy rings.

There are four main species of Cistanche plants in China, among which Cistanche tubulosa has the highest content of active ingredients. In Hotan, 250700 acres of red willows are artificially planted, and 167500 acres of big clouds are planted. Currently, the annual output of red willows and big clouds in the entire region is about 4000 tons. As of now, the artificial red willow Dayun in Yutian County has reached 81000 acres, with a vaccination area of 70000 acres. Among them, 30000 acres of artificial red willow Dayun have completed the certification of organic product production base and AA-level green food base.

Irregular shapes such as spindle-like, flat spindle-like, or flat cylindrical, often twisted, 2-25cm long, 2.6-9cm diameter, surface reddish brown, brown to black brown. The fleshy scales arranged in a tile-like pattern on the surface are dense in the upper part and sparse in the lower part, and the tips of the scales have mostly fallen off. Weight, hard texture, lack of toughness, difficult to break, granular cross-section, mostly gray-brown, and some outer rings have a black hard gum-like appearance. There are numerous black-brown punctate vascular bundles scattered irregularly, some with small fissures.

2, taste

Qi is faint, and tastes sweet and slightly bitter in the mouth.

3, Origin:

Guanhua Cistanche is naturally distributed in the Taklamakan Desert and its surrounding areas in southern Xinjiang, with the Guanhua Cistanche from Hetian as an outstanding representative. Due to the unique biological code constraints and strict requirements for ecological environment and natural climate conditions, Hotan in Xinjiang is the most suitable for the natural growth of Cistanche deserticola. Whether grown naturally or artificially, the effective functional ingredient content of Cistanche deserticola grown in Hotan is 5 to 10 times higher than that of desert Cistanche deserticola.

4, Planting techniques:

The large-scale Cistanche deserticola planted in Hotan is managed and managed by professional institutions. The GAP breeding base implements strict field management for Cistanche deserticola and hires third-party professional institutions to conduct strict real-time monitoring of the base's atmospheric environment, soil, and water quality; Technicians control pests through natural enemies or appropriate artificial pest control, so there is no need to apply chemical insecticides; The base also keeps detailed records of the planting of each Cistanche deserticola plant, and each plant can be directly traced back to the person responsible for planting;

In addition, the irrigation water for the farm comes from pure snow water from the Kunlun Mountains, which is rich in minerals, vitamins, and trace organic matter, allowing Cistanche deserticola to absorb rich nutrients and create a unique and precious value.

5, Active ingredients:

So far, 75 compounds have been isolated from Cistanche deserticola, as follows:

1. Phenylethanoid glycosides

Phenylethanoid glycosides are the main active ingredients in the fleshy stems of Cistanche plants. There are mainly two representative substances, one is echinacoside and the other is verbascoside.

2. Cycloterpenes and their glycosides

It is a white crystalline or amorphous powder, often with optical activity, hygroscopicity, bitter taste, soluble in glacial acetic acid, added with a small amount of copper ions, heated, and shows a blue reaction.

3. Monoterpenes and their glycosides

At present, 7 monoterpenes and their glycosides have been isolated from plants of the Cistanche genus. Its functions have certain physiological activities, such as expectorant, cough suppressant, wind dispelling, sweating, deworming, and analgesic. Essential oils containing terpenes and their derivatives are widely used in spice production.

4. Lignin and its glycosides

Lignin and its glycosides are present in plants and belong to a type of phytoestrogen that has the effects of clearing free radicals and antioxidation in the body. Currently, 2 lignans and 14 lignan glycosides have been isolated from plants of the Cistanche genus. Lignins and their glycosides can bind to estrogen receptors and interfere with cancer-promoting effects. Therefore, it may prevent and regulate breast cancer, prostate cancer, and colon cancer.

Main Chemical Constituents of Cistanche deserticola

5. Carbohydrates and their derivatives

Carbohydrates, also known as carbohydrates, are a general term for polyhydroxyaldehyde or polyhydroxyketone and their condensed compounds and certain derivatives. They are generally composed of three elements: carbon, hydrogen, and oxygen, and are widely distributed in nature. Carbohydrates are important nutrients for the human body, mainly divided into four categories: monosaccharides, disaccharides, oligosaccharides, and polysaccharides, which play important roles in daily life. At present, research has mainly focused on the polysaccharide components in Cistanche deserticola, and 13 polysaccharide components have been isolated.

Extraction technology:

Guanhua Cistanche is also the only Cistanche species that has been separated into multiple effective components through membrane separation technology. Hotan Teichen Company has isolated the main active ingredients, such as echinacoside, verbascoside, and phenylethanolic glycosides, from Cistanche deserticola using membrane separation technology. Its chemical components have multiple functions such as liver protection, sobering up, improving reproductive health, antioxidation, enhancing memory, and delaying aging. It has applied for a patent (CN101041677) and passed the scientific and technological achievement appraisal of Xinjiang Uygur Autonomous Region.
