RP-HPLC法测定肤痒片中山柰素的含量
摘要
目的:建立肤痒片中山柰素的含量测定方法。方法:用Diamonsil C18色谱柱(4.6 mm×250 mm
5μm)
以甲醇-0.4%磷酸溶液(58∶42)
流速为1.0 mL·min-1
检测波长为367 nm。结果:山柰素在(0.041
0
.41)μg范围内呈良好的线性关系
平均回收率和RSD分别为99.1%和1.1%。结论:本方法简便、准确、重现性好
可作为该制剂的含量测定方法。
Abstract
Objective:To develop a RP-HPLC method for determination of kaempferide in Fuyang Tablets.Methods:Diamonsil C
18
column(4.6 mm×250 mm
5 μm)was used
methanol-0.4% phosphoric acid solution(58∶42)as the mobile phase
flow rate at 1.0 mL·min
-1
and the detection wavelength was 367 nm.Results: The calibration curves were linear between(0.041~0.41)μg
The average recovery and the relative standard deviations were 99.1% and1.1%.Conclusions: The method is simple
accurate
repeatable and could be used for determination of kaempferide in the preparation.
