摘要(Abstract):

目的建立RP-HPLC法同时测定元和正胃片中龙胆苦苷、甘草苷、甘草酸、芦荟大黄素、大黄酸5种成分的含量。方法采用Diamonsil C18色谱柱(4.6 mm×200 mm,5μm)进行分离;流动相为乙腈(A)-体积分数0.05%磷酸溶液(B),梯度洗脱,流速1.0 mL·min-1;检测波长为0~35 min、276 nm,35~61 min、254 nm;柱温30℃。结果龙胆苦苷、甘草苷、甘草酸、芦荟大黄素、大黄酸质量浓度分别在29.4~294 mg·L-1(r=0.999 5,n=6)、4.35~43.5 mg·L-1(r=0.999 3,n=6)、8.25~82.5 mg·L-1(r=0.999 7,n=6)、1.27~12.7 mg·L-1(r=0.999 3,n=6)、0.68~6.8 mg·L-1(r=0.999 7,n=6)内与峰面积呈良好的线性关系,方法的平均回收率分别为99.5%(RSD=1.6%)、100.1%(RSD=1.4%)、99.4%(RSD=1.5%)、98.9%(RSD=1.1%)和99.4%(RSD=1.5%)。结论该方法简便、准确、重现性好、专属性强,可用于元和正胃片的质量控制。
Objective To develop an RP-HPLC method for the determination of gentiopicroside,liquiritin,glycyrrhizic acid,aloeemodin and rhein in Yuanhezhengwei tablets(traditional Chinese medicine).Methods HPLC was performed on a Diamonsil C18 column(200 mm×4.6 mm,5 μm)with gradient elution of acetonitrile(A)-0.05% phosphoric acid solution(B)at a flow rate of 1.0 mL·min-1.The UV detection wavelength was set at(0-35 min,276 nm;35-61 min,254 nm),and the column temperature was maintained at 30 ℃.Results The linear ranges were 29.4-294 mg·L-1(r=0.999 5,n=6),4.35-43.5 mg·L-1(r=0.999 3,n=6),8.25-82.5 mg·L-1(r=0.999 7,n=6),1.27-12.7 mg·L-1(r=0.999 3,n=6)and 0.68-6.8 mg·L-1(r=0.999 7,n=6),respectively.The recoveries were 99.5%(RSD=1.6%),100.1%(RSD=1.4%),99.4%(RSD=1.5%),98.9%(RSD=1.1%) and 99.4%(RSD=1.5%),respectively.Conclusions The method is simple,accurate and repeatable and can be used for quality control of Yuanhezhengwei tablets.
