摘要
目的对蒙药阿给生药及炭药中的黄酮类成分进行初步的定性、定量分析。方法采用显色反应进行定性检识,并以芦丁为对照品,采用紫外分光光度法测定总黄酮含量。结果阿给生药及炭药均含有黄酮类成分,但两者所含主要黄酮类成分的类型有所差异;生药与炭药的总黄酮含量分别为4.78%,2.26%,生药总黄酮含量约为炭药的2倍。结论炮制对阿给药材中黄酮类成分类型及总黄酮含量有一定的影响。分光光度法简便灵敏,重现性良好,适用于阿给总黄酮的含量测定。
Objective To identify and determine the total flavonoids in raw and charred Agei. Methods The species of flavonoids in samples were identified by color reactions, and the contents of total flavonoids were measured through UV spectroscopy using turin as control. Results The main species of flavonoids in raw and charred Agei were different, and the average contents of total flavonoids in raw and charred Agei were 4.78% and 2.26% respectively. Conclusion Drug - processing had some effect on the species and the content of total flavonoids in Agei. Spectrophotometry was an easy operated, aceurated, reproducible method for content determination of total flavoniods.
