Technical Field

[0001] The invention relates to the technical field of health beverages, in particular to a method for processing and preparing a Cistanche deserticola drinking liquid rich in seabuckthorn flavonoids. Background Art

[0002] Seabuckthorn is a plant widely distributed in Eurasia. Its fruit is known as the "king of vitamins" and is rich in a variety of biologically active ingredients. Seabuckthorn fruit is rich in nutrients such as vitamin C, vitamin E, carotene, various amino acids and minerals, especially flavonoids, which are one of its main active ingredients. Seabuckthorn flavonoids have significant biological functions such as antioxidant, anti-inflammatory, liver protection, anti-radiation, lowering blood lipids and enhancing immunity. Seabuckthorn has been proven to have a variety of health benefits in traditional medicine and modern scientific research, including the treatment of digestive system diseases, cardiovascular diseases and skin diseases. In addition, seabuckthorn is also widely used in the food, pharmaceutical and cosmetic industries to make a variety of products such as seabuckthorn oil, seabuckthorn juice, seabuckthorn tea, etc.

[0003] Cistanche deserticola is a perennial herbaceous plant that parasitizes on the roots of the desert plant Haloxylon ammodendron. It is mainly distributed in Xinjiang and Inner Mongolia in China. Cistanche deserticola has been known as the "desert ginseng" since ancient times. It is well documented in traditional Chinese medicine books and has a variety of health benefits, including tonifying the kidney and strengthening yang, moistening the intestines and relieving constipation, enhancing physical strength and resisting fatigue. Its main active ingredients include phenylethanol glycosides (such as echinacoside and verbascoside) and polysaccharides. Modern research shows that Cistanche deserticola has a wide range of pharmacological effects, including anti-aging, antioxidant, anti-inflammatory, nerve protection and immunity enhancement. Cistanche deserticola polysaccharides are widely used in the development of health foods and functional beverages by regulating intestinal flora, improving immune function and anti-fatigue effects.
