| 摘 要： | 目的:探讨何首乌属3种药用植物何首乌、毛脉蓼及齿叶蓼根的性状、显微及化学成分的区别,为合理用药提供科学依据。方法:观察何首乌、毛脉蓼及齿叶蓼药材的性状和显微特征,并对3者的LC-ESI/MS图谱进行分析。结果何首乌、毛脉蓼、齿叶蓼根的形态特征、显微结构及化学成分上均存在明显差异:何首乌根断面黄棕色或红棕色,可见"云锦状花纹",韧皮部宽广,可见异常维管束和纤维束,二苯乙烯类成分含量较高。毛脉蓼断面土黄色或黄棕色,韧皮部宽,可见纤维束,主要含有大量的蒽醌类成分;而齿叶蓼断面为红色或紫红色,韧皮部狭窄,细胞多皱缩,未见异常维管束和纤维束,不含有蒽醌及二苯乙烯类成分,主要含有原花青素类成分。结论:何首乌与毛脉蓼在性状及成分类型上具有一定的相似性,只是含量的差异不同,而齿叶蓼则均具有较大的差异性,尤其是不含有何首乌属普遍具有的蒽醌类成分。
