三种缬草属植物的缬草素类含量种间和种内比较

目的:测定不同产地、不同部位三种缬草属Valeriana植物中缬草素类成分的含量。方法:采用RE-HPLC法。结果:蜘蛛香、缬草和宽叶缬草中缬草素类含量差异显著,以蜘蛛香含量最高;不同产地蜘蛛香的缬草素类含量差异较大,以贵州龙里产的最高;不同产地缬草以陕西留坝产的缬草素类成分含量最高;该属植物根茎中缬草素类成分比地上部分含量高。结论:缬草素药用植物中缬草素类成分的种间和种内差异明显。

Interspecific and Intraspecific Comparison of Valepotrates Contents in Three Valeriana Plants

Objective: To compare the contents of three valepotrates interspecifically and intraspecifically in three medicinal Valeriana plants grown in different areas in China. Methods:The method of RE-HPLC was adopted. Results: The results showed that the contents of three valepotriates in Valeriana jatamansi Jones, V. officinalis L. and V. officinalis var. latifolia Miq. were different. Among them, that of Valeriana jatamansi Jones was the highest. The contents of three valepotrates in Valeriana jatamansi Jones varied significantly from different areas, samples collected from Longli of Guizhou province ranking the highest. The contents of three valepotriates in V. officnalis L. also varied significantly from different areas, samples from liuba of Shaanxi province showing the highest. The results also showed that the contents of three valepotriates in underground part are all higher than that in aerial part. Conclusion: The interspecific and intraspecific differences of valepotriates in three Valeriana plans were obvious.
