摘要: 为选取适宜的泡桐叶原料,实现资源的充分有效利用,采用HPLC法考察了不同泡桐种属、存储方法和采集时间等条件下,泡桐叶中熊果酸和齐墩果酸的含量差异。结果表明,白花泡桐叶中熊果酸和齐墩果酸的含量最高,兰考泡桐叶次之,而毛泡桐叶中熊果酸和齐墩果酸的含量明显偏低;阴干后的泡桐叶比鲜叶和冷藏叶中熊果酸和齐墩果酸的含量稍高;从5月份开始,泡桐叶中熊果酸和齐墩果酸的含量逐月增加,在10月份达到最高。

Abstract: In order to select the appropriate Paulownia leaf material,and make full and effective use of resources,the content variations of ursolic acid and oleanolic acid in Paulownia leaves were determined in different Paulownia species,with different raw material storage methods and different harvest times by HPLC.The results showed that the leaves of Paulownia fortunei (Seem.) Hemsl.had the highest contents of ursolic acid and oleanolic acid,followed by the leaves of Paulownia elongata S.Y.Hu,while the contents of ursolic acid and oleanolic acid were significantly lower in Paulownia tomentosa (Thunb.) Steud.leaves.Air-dried Paulownia leaves showed higher contents of ursolic acid and oleanolic acid than fresh leaves and refrigerated leaves.From May,the contents of ursolic acid and oleanolic acid in Paulownia leaves monthly increased,reaching the highest in October.

Key words: Paulownia leaves, HPLC, ursolic acid, oleanolic acid
