摘要
目的:建立同时测定滋补肝肾丸中女贞苷、特女贞苷、异去甲蟛蜞菊内酯和蟛蜞菊内酯含量的方法。方法:采用双波长高效液相色谱法。色谱柱为Elite C18,流动相为乙腈-0.5%醋酸溶液(梯度洗脱),流速为0.9 ml/min,柱温为25℃,检测波长0~30min为224 nm、30~50 min为351 nm,进样量为20μl。结果:女贞苷、特女贞苷、异去甲蟛蜞菊内酯和蟛蜞菊内酯质量浓度分别在6.75~135.00、6.54~130.80、4.90~98.00、6.42~128.40μg/ml范围内与各自峰面积呈良好的线性关系(r=0.999 5、0.999 8、0.999 4、0.999 6);精密度、稳定性、重复性试验的RSD≤1.25%;加样回收率为96.15%~99.96%,RSD〈2%(n=6)。结论:该方法快速、灵敏、准确,可用于滋补肝肾丸中女贞苷、特女贞苷、异去甲蟛蜞菊内酯和蟛蜞菊内酯的含量测定。
OBJECTIVE: To establish a method for simultaneous determination of the contents of ligustroflavone, specnuezhe- nide, demethylwedelolactone and wedelolactone in Zibu ganshen pill. METHODS:Dual-wavelength HPLC was performed on the column of Elite C18 with mobile phase of acetonitrile-0.5% acetic acid (gradient elution) at flow rate of 0.9 ml/min, column temper- ature was 25 ℃, detection wavelengths were 224 nm(0-30 min) and 351 nm (30-50 min), and the injection volume was 20 μl. RESULTS: The linear range was 6.75-135.00 μg/ml(r=0.999 5) for ligustroflavone, 6.54-130.80 μg/ml(r=0.999 8) for specnuezhe- nide,4.90-98.00 μg/ml(r=0.999 4) for demethylwedelolactone and 6.42-128.40 μg/ml(r=0.999 6) for wedelolactone; RSDs of pre- cision, stability and reproducibility tests were no more than 1.25% ;average recoveries were 96.15%-99.96% (RSD〈2%, n=6). CONCLUSIONS: The method is rapid, sensitive and accurate, and can be used for the contents determination of ligustroflavone, specnuezhenide, demethylwedelolactone and wedelolactone in Zibu ganshen pill.
