Pueraria, a leguminous plant known as Kudzu, is a common vegetable in some provinces and autonomous regions of southern China. It is cool and tasty, and is often used for soup. Its main ingredient is starch, in addition it also contains about 12% of flavonoids, including soybean (soybean) wolfberry, soybean aglycone, puerarin and other more than 10 species; and contains carrots, amino acids, coumarins and so on. Can be used as a drug. As early as the time of the gongs, gongs, and gongs, people began to use woven rattan weaving cloth. In 1972, Sandao Mountain in Wu County, Jiangsu Province excavated three pieces of Gebu which were made in the Neolithic Age and are still highly skilled today. These three pieces of Gobi are reliable witnesses that our country has started using Pueraria from more than 6,000 years ago.
chemical composition
Pueraria contains isoflavones puerarin, puerarin xylose, daidzein, daidzein glycosides, and β-sitosterol, arachidic acid, and a large amount of starch (content of fresh Pueraria lobata is 19 to 20%).
The dried roots of the cane vines contained 37% starch.
The root of Schizophyllum japonicum contains 15-20% of starch.
Puerarin, daidzein, daidzein, β-sitosterol, 4′,6′′-diacetylpuerarin, and stigmasterol were isolated from the roots of the same genus in India.
Radix Puerariae contains mainly carbohydrates, plant proteins, vitamins and minerals. It also contains flavonoids: daidzin, soya bean meal, and daidzein-4,7-diglucoside, puerarin, puerarin-7- Xyloside, Pueraria, Pueraria lobata and isoflavone glycosides.
