人工培植牛黄中主要成分的薄层色谱扫描法

天然牛黄为名贵中药材,但货源紧缺供不应求,为此拟利用人工培植方法获得天然牛黄以利扩大药源。本文对十七个人工培植牛黄主成分进行定量分析,并与天然牛黄及人工合成牛黄作对比,从成分上探讨了人工培植牛黄的质量。     

人工培植牛黄中主要成分的薄层色谱扫描法

Natural cow-bezoar is a precious Chinese traditional medicine. Now its supply falls short of demand because of low production. To get "natural cow-bezoar" by artificial culture can increase its production and enlarge its source.In this study the main principles (cholic acid, deoxycholic acid, cholesterol, cholerythrin) of 17 kinds of artificial cow-bezoar were analyzed quantitatively by model CS-930 thin layer scanner, and compared with the natural cow-bezoar and synthetic eow-bezoar. The results indicate that the content of cholerythrin in artificial cow-bezoar is lower than that in natural cow-bezoar, but is higher than that in synthetic cow-bezoar. The total contents of cholic acid and deoxycholic acid in the cow-bezoar which was cultivated more than a year and ten months is higher than that in natural cow-bezoar of the same producing area, but its cholesterol content is lower. The individual exception in the analyses is probably due to difference of the specific animal. Therefore, it is necessar to do further research about this problem.
