Background
Polygonatum sibiricum is a perennial herb of the genus Polygonatum of the family Liliaceae, and more than 40 species of Polygonatum sibiricum have been found to be widely distributed in the northern temperate zone. In China, about 31 polygonatum plants are distributed mainly in Yunnan, Guizhou, Sichuan, Shaanxi, Zhejiang, Anhui and other places. The sealwort is rich in sealwort polysaccharide, anthraquinone compounds, lignans, steroid saponin, alkaloid, multivitamins, cardiac glycoside, trace elements, amino acid and other substances, and has high medicinal value and nutritive value. Rhizoma polygonati has mild and moist medicinal properties, sweet and light taste, no toxicity and disinsection, has the efficacies of strengthening the middle-jiao and replenishing qi, fixing liver and gallbladder, moistening heart and lung, benefiting spleen and stomach, replenishing essence and marrow, strengthening essence and bone, reducing rheumatism and the like, and is known as a good medicine for 'longevity and prolonging life' since ancient times. In recent years, with the development of modern science and technology, the efficacy of polygonatum is studied more deeply, the application of polygonatum is wider, and a batch of polygonatum health care products and health care medicines are continuously appeared, so that the market demand of polygonatum medicinal materials is increased gradually, and the situation that the polygonatum is in short supply in domestic and foreign markets is achieved.
Although the polygonatum has good medicinal value and nutritional value, the wild polygonatum resource storage amount is rapidly reduced and the surrounding environment is damaged due to the large mining.
