摘要:

对银杏叶丛枝叶黄酮类化合物、花青苷、简单酚类、木质素及可溶性蛋白质含量的测定结果表明:黄酮类化合物含量分别在7月4日、11月1日出现高峰;花青苷含量变化与黄酮类化合物类似,但波动幅度大、波动次数相对多;简单酚类含量前期上升,也于7月4日达到第1次高峰,后分别在8月1日和10月17日出现低谷;与黄酮类化合物含量峰相比,木质素第1次峰滞后,第2次峰提前;在前期与后期,可溶性蛋白质含量处于最低时,黄酮类化合物含量在最高峰段。黄酮类化合物与花青苷、简单酚类、木质素呈显著正相关,在7月中旬至9月底,与可溶性蛋白质之间正相关达到显著水平。但偏相关分析表明:黄酮类化合物仅与可溶性蛋白质呈极显著负相关。对叶黄酮类化合物与其转化产物、前体底物及竞争物之间的关系进行了讨论。

Abstract:

The flavonoids, anthocyanin, simple phenols, lignin and soluble protein of the leaves in Ginkgo biloba phyllomes were assayed in 1998~1999. The results indicated that there were two peaks of flavonoids content, one rested on July 4, and the other on Nov.1. The change trend of anthocyanin content with much fluctuation was similar to that of flavonoids content. Simple phenols content rose in the early stage, and reached its first peak on July 4, then its content valleys showed on Aug.1 and Oct.17 apiece. First peak of lignin content was later, and the second peak earlier compared with flavonoids content peaks. There were opposite trends between flavonoids and soluble protein during the early and late stages. It was proved that there was a positive significant correlation between flavonoids and simple phenols, and anthocyanin, and lignin apiece. Positive significant correlation between flavonoids and protein also existed from the middle July to the late September. However, only negative significant correlation between flavonoids and protein was obtained by the analysis of partial correlation. The relationships between flavonoids and its transforming products, and precursors, and competitors were discussed.
