参杞益脑胶囊中β-细辛醚的溶出度研究
摘要
目的:建立了高效液相色谱法测定参杞益脑胶囊中β-细辛醚溶出度的方法。方法:色谱柱为Lichrospher(r)100RP-18e(4.6 mm×250 mm
5μm)
流动相为甲醇-0.1%冰醋酸溶液(60∶40)
柱温35℃
流速1.0 mL.min-1
检测波长257nm
采用转篮法
以0.5%十二烷基硫酸钠溶液500 mL为溶出介质
转速100 r.min-1。结果:β-细辛醚线性范围0.007~0.352μg
胶囊在30 min的溶出度均大于70%。结论:结果准确可靠
可用于参杞益脑胶囊的质量控制。
Abstract
Objective:To establish a high performance liquid chromatographic method to determine the dissolution of β-asarone in Shenqiyinao Capsules.Method:The column was Lichrospher(r) 100 RP-18e(4.6 mm × 250 mm
5 μm).The mobile phase composed of methanol-0.1% glacial acetic acid solution(60∶ 40) and the temperature of column was 35 ℃.The flow rate was 1.0 mL.min-1 and the detective wavelength was at 257 nm
external method.The dissolution of the β-asarone was determined by basket stirring technique with 0.5% sodium dodecyl sulfate 500 mL at a speed of 100 r.min-1.Result:The linear range of β-asarone was 0.007 ~ 0.352 μg.The dissolution of β-asarone was above 70% at 30 minutes.Conclusion:The method is sensitive
accurate and suitable for the quality control of Shenqiyinao Capsules.
