| 摘 要： | 以芦丁为对照品,NaNO2-Al(NO3)3-NaOH体系为显色剂,利用分光光度法测定了穿心莲中的总黄酮含量.确定了总黄酮提取方法、显色剂浓度和显色时间等.回归方程为A=0.00652 11.0329C,相关系数r=0.9997.平均回收率为104.20%,RSD=1.85%(n=5).本法操作简便,可行,重现性好.

| Abstract: | The total flavonoids in Andrographis Paniculata were determined by spectrophotometry with rutin standard and NaNO_2-Al(NO_3)_3-NaOH system.The regression equation is A=0.00652 11.0329C,r=0.9997.The average recovery was 104.20% with the RSD of 1.85%(n=5).The method is simple,reproducible and suitable for the determination of total flavones. |
