摘要
目的考察不同炮制方法对佛手总黄酮含量的影响。方法以紫外-可见分光光度法,NaNO2-AlCl3-NaOH法测定佛手不同炮制品中总黄酮含量。结果以50%乙醇为溶剂时佛手总黄酮提取率高;炮制前后总黄酮含量无明显变化,微波制佛手总黄酮含量较高。结论佛手药材可采用清炒、蒸制、微波等多种方式进行加工处理。
Objective To investigate the effect of different drug processing on contents of the total flavonoids in Bergamot.Methods The NaNO2-AlCl3-NaOH method and UV-visible spectrophotometry were applied to determine total flavonoids in different processed products of Bergamot.Results The highest extraction rate for total flavonoids was obtained with 50% ethanol as extracting media,and the total flavonoids in Bergamot before and after being processed showed no significant change,except for those processed via microwave were more.Conclusion The Bergamot herbs can be processed by frying,steaming and microwaving.
