北京东灵山与雾灵山地区不同生境下柴胡中柴胡皂苷的差异

Differences of saikosaponin contents in Bupleurum chinense from habitats in Dongling mountain & Wuling mountain of Beijing

目的:探讨北京东灵山与雾灵山地区不同生境柴胡化学成分的差异,为认识和发展道地柴胡提供理论依据。方法:对东灵山和雾灵山不同生境类型的柴胡居群进行取样,采用HPLC分析不同生境下柴胡皂苷a和柴胡皂苷d含量的差异。结果:不同生境下柴胡皂苷含量差异显著,草甸生境下的柴胡皂苷含量较高,而林下生境及灌丛生境柴胡皂苷含量相对较低,经分析柴胡皂苷含量与坡向呈正相关,通风透光的生境条件有利于柴胡皂苷的累积。结论:生境对柴胡皂苷产生与积累起着非常重要的作用,建议考察道地药材,应突破传统区域认识,结合生境层级开展。

The different growing habitats of Bupleurum chinense were investigated in Donglin mountain & Wuling mountain areas,the saikosaponin a and d in samples of B.chinense collected from different habitats were determined by HPLC.Results showed that B.chinense distributed in various habitats,such as meadow,understory and brushy.Significant differences of saikosaponin contents were observed.The higher saikosaponins contents were showed in samples from meadow habitats,while the lower saikosaponins contents in sample...
