摘要: The ecological characterstics and genotype difference of functional components between polished and brown rice for 548 accessions core collection for rice landrace (Oryza sativa L.) from 16 prefectures of five rice regions in Yunnan Province were determined. The analytical results are as follows: There are very greater difference for total alkaloid and total flavones contents in rice among five rice regions; the most significant highest total alkaloids and total flavones contents in brown rice from South Yunnan, but the most significant highest in polished rice from Northwest Yunnan. On the contrary, there are very less difference for gamma-amino butyric acid (GABA) and resistant starch (RS) contents in rice among five rice regions, the most significant highest GABA contents in brown and polished rice from Northwest Yunnan, but the most significant highest RS contents from South Yunnan. It is the most significant highest total alkaloids and GABA contents in rice from Chuxiong among 16 prefectute in Yunnan province, meanwhile the most significant highest total flavones from Yuxi prefecture. There are very greater difference for loss rate (%) of four functional component contents from brown rice to polished rice, total flavones (79.8) > total alkaloids (40.6) > GABA (40.3), but interesting no loss of RS. On the whole, there are not only very obvious ecological characterstics of four functional components as well as loss rate of four functional components in brown and polished rice, but also has similar to predominant regions with Yunnan precious traditional Chinese medicine, further discover the root of easy suffer chronic disease for human being.
