云南疣粒野生稻Oryza meyeriana Baill.总黄酮含量分析研究

疣粒野生稻(Oryza meyerianaBaill.)在云南部分地区被用作消炎草药,这种利用行为对该野生稻的生存造成了一定的影响和威胁,为了有效地保护野生稻,对疣粒野生稻是否含有消炎药用成分——总黄酮含量进行了分析。通过本研究,建立了测定疣粒野生稻总黄酮含量的分光光度法,测定了云南省疣粒野生稻2个群体31个居群及居群内单株的总黄酮含量。结果表明疣粒野生稻总黄酮平均含量低于对照银杏叶和竹叶;原生境群体总黄酮含量(1.158g/kg)高于温室群体含量(0.928g/kg),但t测验差异不显著。探讨了云南疣粒野生稻作为消炎草药的可能性和可行性,提出在重要种质资源保护和利用过程中应重视土著知识的利用。

Analysis of the flavones contents of Oryza meyeriana Baill. originated from the Yunnan province

Oryza meyeriana Baill.has been traditionally used as drug to treat disease swelling in some parts of the Yunnan province.Such traditional usage affects the sustainable conservation of O.meyeriana.baill.It is important to analyse flavones contents of O.meyeriana baill.,which is main content to treat disease inflammation in order to conserve effectively the wild rice.A absoptiophotomatric method was established to test the content.The total contents of flavones in 31 populations and 191 individuals of the wild rice were tested.The results show that the total content of flavones in the wild rice is lower than either of gingko leaf as CK1 or bamboo leaf as CK2.The mean total content of flavones of the original group is 1.158 g/kg while that of the greenhouse group 0.928g/kg though their difference is not significant by the T-test.This paper discusses the possibility and feasibility to use O.meyeriana Baill.as drug to treat disease inflammation.It puts forward to paying much attention to protection of indigenous knowledge when using and conserving important germplasm resources.
