摘要：目的:探讨中药当归中无机元素含量及其分布规律与药材生长环境的关系。方法:采用微波消解-原子吸收光谱法测定95批不同生长环境当归样本中Zn、Fe、Mn、Mg、Ni、Ca、Na、K和Cu等9种无机元素的含量,采用主成分分析和系统聚类分析进行分析和评价。结果:主成分分析表明,Mn、Mg、Ni和K是当归药材的特征性无机元素;系统聚类分析可将95批当归样本分为4类,第Ⅰ类当归样本的土壤类型以黑土和黑砂土为主,第Ⅱ类以褐砂壤、褐土及黑麻土为主,第Ⅲ类以黑麻土为主,第Ⅳ类以黄土和黄绵土为主。结论:中药当归中无机元素分布与其生长的土壤类型密切相关。
OBJECTIVE To investigate the relationship between the contents and distribution of inorganic elements in Angelica sinensis and its growing environment. METIIODS The contents of Zn, Fe, Mn, Mg, N1, Ga, Na, K and Cu in 95 batches of Angelica sinensis from different growing environment were determined by microwave digestion-atomic absorption spectroscopy, and principal component analysis and cluster analysis were used for analysis. RESULTS The results of principal component analysis showed that Mn, Mg, Ni and K were the characteristic elements in Angelica sinensis. The results of systematic cluster analysis showed that 95 batches of Angelica sinensis were clustered into 4 different groups. The main soil types of group Ⅰ were black soil and black sandy-soil, group Ⅱ were cinnamon sandy-loam, cinnamon soil and haplic kastanozems, group Ⅲ was haplic kastanozems, and group Ⅳ were loess and loessial soil. CONCLUSION The distribution of inorganic elements in Angelica sinensis is closely related to the types of its growing soil.
