Fagopyrum Pharmacognosy And Chemical Composition Study

Fagopyrum dibotrys (D.Bon) Hara, is a medicinal plant from Fagopyrum genus, Polygonaceae. There are 15 species in Fagopyrum genus all over the world, and 8 species in our country. Among them more than 4 species can be used to treat diseases. Fagopyrum plants distribute in the high and cold mountain regions of northwest, northeast, southwest and north china. And the plants resources are very abundant. Most of them can clear away heat and detoxicate toxity, and some of them have been used to cure various diseases. Modern pharmacologic researches found that the components coming from Fagopyrum have obvious effection on anti-tumor,declining the blood-sugar and fat,anti-rheumatism. So they are good anti-cancer, declining the blood-sugar and fat , anti- rheumatism medicine. In addition, they also have effection on antibiosis, anti-inflammatory, antibechic, resolving phlegm and relieving pains.The chemical researches of Fagopyrum plants discover that the flavonoid compounds in the plants of Fagopyrum show intensive physiologic activity of anti-tumor and oxidation, declining the blood-sugar and fat, resist rheumatism,etc. Cancer, diabetes, hyperlipoproteinemia and rheumatism have become the serious diseases damaging human health, but the Fagopyrum plants can treat these diseases well. So, there is an extensive market foreground in the space of developing some new medicines to cure cancer, diabetes hyperlipoproteinemia and rheumatism from the medicinal plants of anti-tumor and declining the blood-sugar and fat and anti-rheumatism strongerly.Currently, there are still many medicinal plants of Fagopyrum which have not been studied in deepth, we should keep with the opportunity to study them, and lay stress on the protecting, developing, making use and studying on the resources of the medicinal plants.F. dibotrys is one of the medicinal plants used usually in our country, its former study has found out to have good anti-tumor activity. In this paper we worked on its constituent isolation, structure determination and quality control on the basis of the antecedent research.This paper summarizes the research survey of Fagopyrum plants from consititution, pharmacological action and so on. And this thesis carries on the research on structure determination and chemical compounds in F. dibotrys, it provides methods to identify F. dibotrys; we...
