不同变异类型杜仲皮中几种主要活性成分含量的比较

Comparison of the Main Active Components Contents in Barks of Different Variance-types of Eucommia ulmoides

采用反相高效液相色谱法测定了不同变异类型杜仲皮中几种关键活性成分的含量,结果表明:4种变异类型杜仲皮中5种不同活性成分的含量及组成比有较大差异,其中京尼平苷酸(GPA)、京尼平苷(GP)、松脂素二糖苷(PDG)、绿原酸(CA)含量以及5种成分的总含量以光皮型和浅纵裂型杜仲皮较高,而龟裂型和深纵裂型活性成分总体含量较低。若遴选优质杜仲药用资源,可首先考虑从优良光皮型和浅纵裂型杜仲群体中开展选育工作。

To reveal the natural active component variation rule in barks of Eucommia ulmoides Oliv.,which provided basal reference for the plus tree screening and effective utilization of the medical woody plants,the active components in barks of different Eucommia ulmodies variance-types were detected by RP-HPLC.The results showed that the content and allocation of the five active components in barks was evidently different among four variance-types.Comparing to the deep-vertical splitting and the chap variance-types,four natural contents including geniposidic acid,geniposide,pinoresinol diglycoside,chlorogenic acid and total amount of the five constitutes were detected to be relatively higher in barks of the smooth and the shallow-vertical splitting types.Community of the smooth type could be given priority to breeding selection for cultivating excellent Eucommia ulmoides medicinal variety.
