urson

1.Silica gel column separation method and spectrophotography were used to determine the content of urson in the preparation.

采用硅胶柱分离分光光度法,对制剂中所含熊果酸成分进行含量测定,结果含量测定的标性关系好,检测数稳定。

2.METHOD Qualitative test with thin-layer chromatography was performed on Yunkeping Granule, with Spica Prunellae Vulgaris, Herba Plantaginis and urson as the control.

方法采用以、车前为对照药材,以熊果酸为对照,对晕可平冲剂进行了薄层层析定性检测研究。
