摘要:  三氯化铝与黄酮类化合物作用后,生成黄酮的铝络合物为黄色,使用分光光度计比色测定得光密度,计算黄酮类化合物的含量。经反复试验探讨,研究结果表明:浸提茶水比为1:80,浸提时间为60min时,桑叶茶的黄酮类化合物浸出量最大,测定结果重现性较好。

Abstract:  Let the AlCl3react on anthoxanthin compound to yield the yellow complex of anthoxanthin-aluminum.The anthoxanthin compound content was obtained by determining OD with photoelectric colorimeter.After testing repeatedly,the results showed that the extracts were maximum with material to water ratio at 1∶80 and 60 min time.Furthermore,the epeadability of the determintion results.
