摘要
目的:分析甘肃栽培当归外观性状差异,探讨与其质量的相关性。方法:测量22组不同产地当归药材的性状指标,采用中国药典方法测定阿魏酸、挥发油和浸出物含量,用SPSS15.0软件统计分析。结果:产地与性状指标,以及性状指标间均呈正相关,其中有9组性状指标间达到极显著相关,产地与除当归头长度外的其他指标达到极显著相关;浸出物、阿魏酸与产地、性状指标呈正相关,其中浸出物与性状指标均达到显著相关,阿魏酸仅与当归头长度显著相关,而挥发油仅与产地显著相关,与性状指标无明显的相关性;根重、侧根数在产地间差异较大,变异系数分别为44.1%和28.6%。结论:当归药材存在显著的个体差异,化学成分与性状指标有一定的相关性,当归种植需要考虑产地的选择。
Objective：To analyze the appearance differences of Gansu cultivated Angelica sinensis, and explore the relevance between the appearance differences and quality. Methods： The macroscopic feature of 22 batches of Angelica sinensis from different habitats was measured as index. The content of ferulic acid, volatile oil and extract were determined by the method recorded in the Chinese Pharmacopoeia. The data were analyzed by SPSS 15.0 software. Results：The habitat was positively correlated with the index. Indexes of nine groups had direct correlation with each other. The habitat was significantly correlated with other indexes except the length of the head. The extract and ferulic acid were positively correlated with habitat and index. Extract had significant correlation with macroscopic feature. Ferulic acid only had significant correlation with head length. The volatile oil only had significant correlation with habitat and no significant correlation with index. Root weight and number of lateral roots had obvious difference in different habitat which coefficient of variation was 44. 1% and 28. 6% , respectively. Conclusion：There are significant individual differences in Angelica sinensis. The chemical composition has a certain correlation with macroscopic feature. Angelica sinensis cultivation needs to consider the choice of habitat.
