大血藤黄酮类化合物组成的初步研究

A primary study on the flavonoids from Sargentodoxa cuneata

大血藤为一种传统药用植物。为了了解大血藤的药用成分,利用聚酰胺薄层层析及HPLC法分析了大血藤各器官黄酮类化合物的组成。聚酰胺薄层层析及HPLC法分析都显示大血藤叶片含有10种不同的黄酮甙,而嫩茎、叶柄与老茎中分别含有10种、8种及5种不同的黄酮甙;大血藤叶片黄酮类化合物经盐酸水解后HPLC分析显示有8种不同的黄酮类化合物。大血藤叶片及嫩茎的黄酮类化合物组成成分较多,具有一定的应用开发前景。

Sargentodoxa cuneata is a traditional Chinese medicine.In order to find out the primary effective components,the flavnoids in different organs were extracted and analyzed by HPLC and polycrylamide membrane chromatography.The results showed that there were 10,10,8 and 5 kinds of flavonoids in the leafblade,twig,leafstalk and stem,respectively.The HPLC analysis of the hydrolyzed flavnoids extracted from the leafblades of Sargentodoxa cuneata suggested that there were 8 kinds of flavonoids in leaflades of Sargentodoxa cuneata.The relatively more components in the leafblades and twig suggested that there was wide application of  Sargentodoxa cuneata.
