对中国各地栽培的当归进行质量考察;重点了解甘肃省岷县露天与地膜两种栽培方式对品质的影响;比较归头、归身和归尾不同部位的质量。采用UV法测定多糖及HPLC法测定阿魏酸和藁本内酯含量;以及其有机氯农药残留量等检查。不同产地的当归以及当归药材不同部位中多糖、阿魏酸和藁本内酯有明显的差异:有机氯残留量符合有关规定。中国栽培当归质量符合中国药典规定。甘肃省岷县当归品质优良;当归中所含多糖、阿魏酸及藁本内酯与产地、栽培方式有一定的相关性。
The quality of the cultivated Angelica sinensis in different parts of China was investigated. The influence of open-field and plastic-film cultivation on the quality of Minxian county in Gansu province was mainly studied. The quality of the different parts of the population was compared. The content of ferulic acid and ligustilide were determined by UV spectrophotometry and HPLC, and the residues of organochlorine pesticides were also examined. Angelica from different areas and Angelica Angelica different parts of polysaccharides, ferulic acid and ligustilide significant differences: residues of organic chlorine in line with the relevant provisions. Chinese cultivation Angelica quality in line with the provisions of Chinese Pharmacopoeia. Angelica sinensis in Gansu Province is of good quality.
