The flavonoids in Panax notoginseng were analyzed, and flavonoids A and B were obtained. Part A can be isolated to obtain quercetin, which has the functions of dispelling diseases, relieving cough, relieving asthma, and lowering blood pressure. However, there are few chemical and pharmacological studies on Panax notoginseng, the content of Panax notoginseng is low, and its chemistry and activity need further research. What are the active ingredients of Panax notoginseng? Saponin composition The root tuber of Panax notoginseng is the main medicinal part of Panax notoginseng, containing about 7% of the total glycosides. Among these dozens of Panax notoginseng saponins, the monomer saponins are mainly ginsenosides Rg1, Rb1, Rd, and Panax notoginseng saponins R1, accounting for about 80% of the total saponins. The ratio of these four saponins is roughly 5:3:1:1. In the whole plant of Panax notoginseng, the saponins only contained in the roots are Panax notoginsenoside-B1, ginsenoside Rf, notoginsenoside-R3, notoginsenoside-R6. Perhaps these are the reasons that determine the medicinal value of Panax notoginseng... Sugar components Panax notoginseng contain monosaccharides (rhamnose, xylose, and glucose), oligosaccharides, and polysaccharides. The oligosaccharides in Panax notoginseng are mainly sucrose, and the polysaccharides include starch, cellulose, hemicellulose, other glucans, fructans, gums, etc. Amino acid composition In 1988, Lu Qi and other scholars analyzed and tested the amino acids in Panax notoginseng. A total of 16 amino acids were determined, of which 7 were essential amino acids. The average content of total amino acids was 7.73%. Other active ingredients The volatile oil in Panax notoginseng has a strong aroma of Panax notoginseng and has unique uses in medicine, food, beverages, cosmetics, and deep processing of Panax notoginseng. Panax notoginseng also contains chemical substances such as vegetable oils, sterols, blocks, olefins, and hydrocarbons. β-Sitosterol is isolated from the root of Panax notoginseng. Sitosterol has the functions of lowering blood lipids and resisting skin ulcers. In 1993, Yang Ping and other scholars separated from the fat-soluble part of Panax notoginseng and obtained an alkene compound - ginseng alkene triol. Pharmacological studies have shown that the compound has a strong anticancer effect.
