宣痹凝胶贴膏剂中龙胆苦苷、柚皮苷、原苏木素B含量测定
摘要
目的:建立宣痹凝胶膏剂中龙胆苦苷、柚皮苷、原苏木素B含量测定方法。方法:采用高效液相色谱法
MerckRP-C18色谱柱(4.6 mm×250 mm
5μm)
流动相乙腈-0.1%磷酸梯度洗脱(0~33 min
11%乙腈;33~36 min
11%乙腈~20%乙腈;36~67 min
20%乙腈)
柱温20℃
流速0.6 mL·min-1
检测波长283 nm
进样量10μL。结果:龙胆苦苷、柚皮苷、原苏木素B分别在0.014 9~0.745 0μg
0.007 1~0.355 0μg
0.002 2~0.107 5μg呈良好的线性关系
平均回收率分别为98.87%(RSD 2.19%)
103.51%(RSD 0.94%)
99.58%(RSD 2.49%)。结论:方法操作简便
准确
重复性好
可作为宣痹凝胶膏剂的质量控制。
Abstract
Objective:To establish content determination method for gentiopicroside
naringin and protosappanin B from Xuanbi gel plaster.Method:HPLC was used with Merck RP-C18 column(4.6 mm×250 mm
5 μm)
gradient eluted with mobile phase of 0.1% phosphoric acid-acetonitrile(0-33 min
11% acetonitrile;33-36 min
11% acetonitrile-20% acetonitrile;36-67 min
20% acetonitrile)
column temperature was 20 ℃
flow rate was 0.6 mL·min-1
detection wavelength 283 nm
injection volume was 10 μL.Result:The linear range of gentiopicroside
naringin and protosappanin B were 0.014 9-0.745 μg
0.007 1-0.355 μg
0.002 2-0.107 5 μg
respectively.Average recovery of these ingredients were 98.87%(RSD 2.19%)
103.51%(RSD 0.94%)
99.58%(RSD 2.49%)
respectively.Conclusion:This established method was simple
accurate and repeatable
it could be used as quality control method for Xuanbi gel plaster.
