摘要
目的 建立利胆排石片中游离蒽醌、总蒽醌和结合蒽醌的高效液相色谱测定方法。方法 采用Phenomenex Luna 5u-C18色谱柱(4.6 mm×250 mm,5μm),以甲醇(A)-0.1%磷酸水溶液(B)为流动相,梯度洗脱,流速1 m L/min,检测波长:254 nm。结果 各待测组分分离度良好;芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚5个成分的进样量在2.408~24.08 ng(r=0.9996),2.718~27.18 ng(r=0.9999),3.060~30.60 ng(r=0.9995),4.298~42.98 ng(r=0.9999),3.050~30.50 ng(r=0.9998)与峰面积呈良好的线性关系;游离蒽醌中芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚的加样回收率(n=6)分别为:99.1%(RSD=1.3%),98.6%(RSD=1.1%),99.0%(RSD=1.4%),98.5%(RSD=0.8%),99.7%(RSD=1.0%);总蒽醌中芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚的加样回收率(n=6)分别为:98.4%(RSD=0.6%),99.5%(RSD=0.9%),98.8%(RSD=1.2%),99.3%(RSD=0.8%),99.1%(RSD=1.3%)。结论 经方法学验证,本方法简单、快速、灵敏、准确,可用于利胆排石片的质量控制定量分析方法。
Objective To develop an HPLC method for determination of free anthraquinones, total anthraquinones and conjugated anthraquinones in Lidan Paishi Tablets. Methods The chromatographic separation was performed on Phenomenex Luna 5u-C18 (4.6 mm × 250 mm, 5 μm) with mobile phase consisting of methanol (A) -0.1% phosphoric acid solution (B) in a gradient mode at a flow rate of 1 mL/min. The UV detection wavelength was set at 254 nm. Results Excellent chromatographic separation was achieved and the ranges for linear correlation of aloeemodin, rheim emodin, chrysophanol and physcion were 2.408-24.08 ng (r=0.9996), 2.718-27.18 ng (r=0.9999), 3.060-30.60 ng (r=0.9995), 4.298-42.98 ng (r=0.9999), 3.050-30.50 ng (r=0.9998), respectively. Of free anthraquinones, the average recoveries (n=6) of aloeemodin, rhein, emodin, chrysophanol and physcion were 99.1% (RSD=1.3 %), 98.6 % (RSD=1.1%), 99.0 % (RSD=1.4 %), 98.5 % (RSD=0.8 %), 99.7 % (RSD=1.0 %); of total anthraquinones, the average recoveries (n=6) were 98.4 % (RSD=-0.6 %), 99.5 % (RSD=0.9 %), 98.8 % (RSD=1.2 %), 99.3 % (RSD=0.8 %), 99.1% (RSD=-1.3 %), respectively. Conclusion By method validation, this method is proved to be simple, rapid, sensitive and accurate. It's an available quantitative analysis method for quality control of Lidan Paishi Tablets.
