摘　　要：建立了白花蛇舌草药材弱极性和中等极性组分HPLC特征指纹图谱的分析方法,通过相似度和聚类分析,对不同产地、正伪品种进行了质量评价.结果表明,白花蛇舌草样品同一产地化学组成相似,具有一定的地域性,伪品水线草化学组成与其相差甚远.因此,采用相似度和聚类分析能够反映出白花蛇舌草药材弱极性和中等极性组分具有地域性差异,为白花蛇舌草药材产地选择及质量控制提供依据.The analytical method was established to investigate the minor polar and middle polar components from Hedyotis diffusa Willd.The similarity and cluster analysis methods were applied to study the HPLC fingerprint of the minor polar and middle polar components of Hedyotis diffusa Willd.and its substitutes for quality control from different places.The obvious effect of hierarchical clustering has been obtained by HPLC fingerprint analysis with the minor polar and middle polar extracts of Hedyotis diffusa Willd.from different places including reference herb.And its substitutes from different places have favorable hierarchical clustering.The components from its substitutes differ greatly with those of Hedyotis diffusa Willd..Therefore,the diversities of the minor polar and middle polar components of Hedyotis diffusa Willd.from different places were observed using the similarity and cluster analysis methods.
