Abstract: China is one of the major produce Natural Medicines country with his more than 30,000 higher plants, and also occupies head of the Northern Hemisphere. Exploituring variety of new drugs from natural products attracted the scientists for their studies in recent 20 yeas. In China, the research of plant resources has enormous progress since1970s. China is the world center of buckwheat?origin and genetic diversity. Fagopyrum dibotrys., one of perennial herbs of the genus Polygonaceae in the Fagopyrum Mill family, origins from southwest of china, and ranges from Shanxi, Jiangsu, Zhejiang, Jiangxi, Henan, Hunan, Hubei, Guangxi, Guangdong, Sichuan, Chongqing and Yunnan ect.. It is an important resource plant with rich nutrition and medicinal utilization values, and contains a large number of excellent genes. As an important tradition Chinese Medicinal Materials, the active extract of earthnut (secondary metabolites ) of Fagopyrum dibotrys is one of main constituent of many efficient drugs, and has prominent functions in anti-cancer, controlling tumour cell affect and transfering to lung, and anti-inflammatony antibacteria ect.Besides, because proteins of its seeds are complete, contents of necessary amino acid are high, and vitamin and microelement are rich, it becomes one of perfect health-care foods. At present, cultivated yield is restricted, and cultivated species are lower than wild type in nutrition worth, efficient constituents for medicine and titer, which leads to requesting for Fagopyrum dibotrys largely, so that wild resource is destroyed greatly. In view of the conditions, it is ranked into the second degree of national protected plants. Domestically and abroad resource collection, diversity, physiological characteristic, breeding, pharmacodynamics and ecology environment and other aspects are outspread, however, in the light of function genes research relating to active components of medicine not reported. In order to explore worth of Fagopyrum dibotrys further, and its excellent function genes ,and protect wild resource, in this article , summarize new headway and prospect of Fagopyrum dibotrys in original plant classifying and distributing, diversity, nucleus shapes, chemical and functional components , pharmacology , ecology environment, breeding and tissue culture.
