摘要:
目的:建立远志流浸膏中远志酸含量测定的高效液相色谱法。方法:样品经盐酸溶液水解,沉淀经水洗后用甲醇溶解,进高效液相色谱仪进行检测。色谱条件: XBridge C18(5μm,4.6×150mm)色谱柱,流动相为乙腈-0.2%磷酸溶液(40:60),检测波长210nm,柱温为30℃,进样量为20μL。结果:远志酸的浓度在5~500μg/mL范围内呈良好的线性关系,线性回归方程为y=9834x-24784,相关系数r=0.9999。结论:该方法简便,灵敏度高,为远志流浸膏质量标准的研究提供了科学依据。

Abstract:
AIM: To establish a method of HPLC for determination of Polygalacic acid in Extractum Polygalae Liquidum.METHODS: Polygalacic acid in Extractum Polygalae Liquidum were determined on HPLC,acetonitrile- 0.2%H3PO4 (29:31) as mobile phase ,the detection wavelength was 210nm.RESULTS: The equation was: y=9834x-24784, r=0.9999,the calibration curve was linear in the range 5~500μg/mL. CONCLUSIONS:The method is simple and with high sensitivity,and provide the scientific evidence for the research of the quality standard of Extractum Polygalae Liquidum.
Key words:  Extractum Polygalae Liquidum  Polygalacic acid  HPLC
