目的 建立决明子中橙黄决明素、芦荟大黄素、大黄酚、大黄素、大黄酸、大黄素甲醚6个成分的HPLC测定方法,比较生、炒决明子中化学成分含有量的差别.方法 采用Kromasil C18色谱柱(150 mm×4.6 mm,5μm),以乙腈(A)-0.1%磷酸水溶液(B)为流动相,梯度洗脱,体积流量为1.0 mL/min检测波长为284 nm.结果 生、炒决明子中6个成分橙黄决明素、芦荟大黄素、大黄酚、大黄素、大黄酸、大黄素甲醚进样量分别在0.114 4 ~1.144 μg(r =0.999 2),0.037 60~0.3760 μg (r=0.999 1),0.1660~1.660 μg (r=0.9990),0.0242~0.2420 μg (r=0.999 4),0.252 8 ~2.528 μg(r=0.999 4),0.03520~0.3520 μg (r=0.9992)范围内与峰面积呈良好线性关系;平均回收率(n=5)分别为97.0%、98.4%、98.0%、98.2%、97.1%、97.8%.结论 决明子经炒制后6个蒽醌类成分的量降低.
目的 建立決明子中橙黃決明素、蘆薈大黃素、大黃酚、大黃素、大黃痠、大黃素甲醚6箇成分的HPLC測定方法,比較生、炒決明子中化學成分含有量的差彆.方法 採用Kromasil C18色譜柱(150 mm×4.6 mm,5μm),以乙腈(A)-0.1%燐痠水溶液(B)為流動相,梯度洗脫,體積流量為1.0 mL/min檢測波長為284 nm.結果 生、炒決明子中6箇成分橙黃決明素、蘆薈大黃素、大黃酚、大黃素、大黃痠、大黃素甲醚進樣量分彆在0.114 4 ~1.144 μg(r =0.999 2),0.037 60~0.3760 μg (r=0.999 1),0.1660~1.660 μg (r=0.9990),0.0242~0.2420 μg (r=0.999 4),0.252 8 ~2.528 μg(r=0.999 4),0.03520~0.3520 μg (r=0.9992)範圍內與峰麵積呈良好線性關繫;平均迴收率(n=5)分彆為97.0%、98.4%、98.0%、98.2%、97.1%、97.8%.結論 決明子經炒製後6箇蒽醌類成分的量降低.
