川芎HPD-100大孔树脂和醇沉纯化物指纹图谱研究
摘要
目的:建立川芎HPD-100大孔树脂纯化物及醇沉纯化物的指纹图谱
筛选较优纯化方法并为有效控制其质量提供可靠方法。方法:高效液相色谱法
Phenomenex Hyperclone BDS C18(4.00 mm×250 mm
5μm)
甲醇-1%冰乙酸为流动相
梯度洗脱(0~35 min
20∶80~45∶55
35~55 min
45∶55~70∶30
55~70 min
70∶30~80∶20)
322 nm检测。结果:川芎HPD-100大孔树脂纯化物共有22个共有峰
川芎醇沉纯化物共有20个共有峰
分离好
相似度均在0.98以上
重复性好。结论:川芎采用HPD-100大孔树脂纯化较好。本方法科学、准确、专属性好
可为川芎药材及含川芎的中成药质量控制提供可靠的科学依据。
Abstract
Objective:To establish the HPLC fingerprint of Chuanxiong Intermediate and provide a method to control the quality of Chuanxiong.Method:HPLC method was applied for quality assessment of Chuanxiong Intermediate.HPLC analysis was performed on a Phenomenex Hyperclone BDS C18(4.00 mm×250 mm
5 μm) by gradient elution using methanol-1% acetic acid solution as mobile phase.Flow-rate was 1 mL·min-1.The detection wavelength was at 322 nm.Result: The intermediate of Rhizoma Chuanxiong were closely related to each other.Conclusion: The method is rapid and accurate.It was used for determination of Chuanxiong Intermediate and Chinese formulated medicine with it.
