四川大头茶黄酮类化合物的聚酰胺薄膜层析分析

 四川大头茶是一种分布很广的常绿乔木，其次生代谢特征随地理分布的不同有很大的差异。运用聚酰胺薄膜层析和定量分析方法，分析了来自云南文山老君山、四川丹棱、四川兴文、四川缙云山、广西阳朔三岔河、广西阳朔三盘、广西贺县姑婆山的四川大头茶的黄酮类化合物。结果表明，不同地理种源的四川大头茶其黄酮类化合物的类型有很大的差异。根据黄酮类化合物的差异，可以把四川大头茶划分为中纬度、中海拔分布；低纬度、中海拔分布；低纬度、高海拔分布3种地理分布类型。

Polyacrylamides Membrane Chromatogrphy of Flavonoids in Gordonia acuminata

Gordonia acuminata is a widely distributed tree species. Its secondary metabolism features differ significantly with its geographical distribution. By the method of polyacrylamides membrane chromatography and quantitative analysis, the flavonoids in G. acuminata were analyzed using the samples collected from Mt. Laojun (situated in Wenshan, Yunnan), Danling (in Sichuan ), Xingwen (in Sichuan), Mt. Jinyun (in Sichuan). Sanchahe (in Yangshuo, Guangxi) Sanpan (in Yangshuo,Guangxi), Mt. Gupo (in Hexian,Guangxi). The results show that G. acuminata plants collected from different geographical regions were very different in flavonoids components. Based on the variations in flavonoids components, three kinds of geographical distribution patterns of G. acuminata were distinguished: (1) higher elevation and lower latitude distribution, (2) middle elevation and lower latitude distribution, and (3) middle elevation and middle latitude distribution.
