HPLC测定不同产地金银花中绿原酸和木犀草苷
摘要
目的:建立高效液相转换波长法
同时测定金银花中绿原酸和木犀草苷的含量。方法:采用Hypersil gold C18色谱柱(4.6 mm×250 mm
Objective:To establish a wavelength conversion method for determination of chlorogenic acid and galuteolin in honeysuckle simultaneously.Method:The separation was performed on a Hypersil gold C18 column (4.6 mm × 250 mm
5 μm).Acetonitril-0.05% H3P04 was used as the mobile phase with gradient elution.The flow rate was 0.5 mL·min-1.The detection wavelength was at 327 nm and 350 nm.Result:The linear range(n=5)was 0.06 × 103-0.42 × 103 mg·L-1(r=0.999 9) and 0.716-5.728 g·L-1(r=0.999 95) respectively.The average recoveries(n=6) of chlorogenic acid and galuteolin were 101.15% and 99.80% respectively.Conclusion:This method is sensitive
reliable and can be applied to determine chlorogenic acid and galuteolin in the raw material of honeysuckle.
