摘要
目的 测定复方银杏胶囊中总黄酮的含量 ,从而对本品质量进行控制。 方法 采用紫外分光光度法测定。 结果 芦丁的线性范围为0 .0 12～ 0 .0 60 m g· m L- 1 ,回归方程为 Y=12 .4x-0 .0 13 ,相关系数 r=0 .9998,加样回收率为 99.3 7% ,RSD为 0 .8161%。 结论 该法简便易行、快速、准确、可以用于本品的质量控制方法之一。
OBJECTIVE To determine the Flavonoids in Compound Ginkgo Capsule .To control the quality of the drug.METHODS UV menthod.RESULTS The calibration curve is linear in the range of 0.012～0.06mg·mL -1 ,and regression equation was Y=12.4x-0.013(r=0.9998)for quercetin.The average recovery was 99.37% with RSD=0.8161%.CONCLUSION The method is simple quick and accurate for the determination of the Compound Ginkgo Capsule also can be used as one of the quality control methods for the Compound Ginkgo Capsle.
