摘要/Abstract

摘要： 对银杏不同枝类、叶位叶及叶柄黄酮含量进行全周期测定, 结果表明: 叶黄酮含量, 长枝叶最高; 长枝有3 次高峰, 中短枝和叶丛枝各有2 次高峰, 均以最后一次峰值最大。叶黄酮含量增长幅度同时期相比为长枝> 中短枝> 叶丛枝> 叶柄。在生长发育后期, 叶片与其叶柄黄酮含量变化趋势相反, 长枝不同叶位叶黄酮含量最大值是中部叶> 基部叶> 顶部叶。就叶黄酮含量变化及分布与叶片采收、分级及修剪等关系进行了讨论。

Abstract: The flavone contents of Ginkgo biloba leaf stalks and leaves in different types of the branches and leafpositions were assayed in 1999. The results indicated that the flavone content rested on long-branch leaves had three
peaks , but only two peaks in both middle-short branch leaves and phyllome-branch leaves. Of all the peaks , the last one showed the highest value in all types of the branches. At the same time , the increasing speeds of flavone contents queued from fast to slow: long-branch leaves , middle-short branch leaves , phyllome-branch leaves and the leaf stalks. However there was an opposite trend of the change of flavone content in the leaves and its leaf stalk during the late stage. Flavone content in the middle-position leaves of long2branches was the highest , that in the basal leaves was the second ,
and that in the top-position leaves was the last. The relationship of the change of flavone content and its distribution with leaf classification , collection and trimming were discussed.
