摘要
目的:研究不同基源及产地桑椹药材的品质差异。方法:建立桑椹药材的HPLC分析方法,比较不同样品的HPLC图谱相似度,并进行聚类分析。结果:16批桑椹样品相似程度不高,不同基源及产地样品的化学成分在组成与数量上存在差异,桑椹药材的品质与产地无明显相关性,杂交桑的桑椹总峰面积大于法定品种的桑椹总峰面积,市购商品药材品质差异大。结论:桑椹药材的品质与原植物种质、药材加工及贮存有较密切的关系。
Sixteen Fructus Mori samples of different origins and habitats were compared for quality difference according to their characteristic HPLC profiles and subjected to hierarchical cluster analysis. Besides, the optimal chromatographic conditions were discussed. A low similarity in HPLC profile and remarkable differences in content and chemical composition were observed among the 16 samples. There was no obvious correlation between quality and habitat of Fructus Mori. Samples from half-bred mulberry varieties displayed larger peak area than those stipulated in the Chinese pharmacopoeia. Commercial Fructus Mori products differed greatly in quality. All these results reveal that Fructus Mori quality is closely associated with mulberry variety, processing and storage.
