    不同种源青钱柳叶黄酮类物质含量的动态变化

    Dynamic change of flavonoids content in Cyclocarya paliurus leaves from different provenances.

    • 摘要: 通过对5个种源青钱柳叶片黄酮类物质生长期动态规律的分析,寻求最适宜的利用时期,并初步筛选优良种源。基于高效液相色谱分析数据,对其功能叶黄酮类物质含量进行统计分析。结果表明:不同月份黄酮类物质含量差异显著,湖南江华和江西庐山种源的最佳采收期为7月,其他种源为10月;不同种源间黄酮类物质含量变异极显著,初步筛选出江华和庐山为优良药用种源。

       

      Abstract: The dynamics of flavonoids content during the growing period of Cyclocarya paliurus leaves from five provenances was studied to determine the optimum harvesting time of leaves and to select superior provenances. The content of flavonoids in the leaves was determined with HPLC and the data analyzed by SPSS software. Results indicated that there were significant differences in flavonoids content of leaves among different harvesting months for each provenance. The best harvesting time was in July for Jianghua and Lushan provenances, and in October for the other provenances. Significant differences in the average flavonoids content of leaves were also observed among different provenances, and the Jianghua and Lushan provenances were considered elite ones for medicine use in light of flavonoids content. The obvious differences mentioned above made it necessary to choose the best utilization time and to select superior provenances in order to make full use of C. paliurus leaves.
