铁棍山药皮中三个菲类化合物的含量测定
Determination of three phenanthrenes in the peels of Dioscorea opposita Thunb. cv. Tiegun
【摘要】 目的 建立高效液相色谱法测定铁棍山药皮中三个菲类化合物的含量。方法 采用ZORBAX Eclipse XDB C8(5 μm,4.6 mm×150 mm)色谱柱,以乙腈(A)-0.1%甲酸水(B)溶液为流动相,进行梯度洗脱,洗脱梯度(0~15 min,25%→30%A;15~45 min,30%→45%A),流速1.0 mL·min-1,检测波长260 nm。结果 三个化合物在0.02~0.12 mg·mL-1内与峰面积均呈良好的线性关系(R2>0.999),精密度、稳定性、重复性良好,平均加样回收率为98.23%~106.02%,RSD为2.4%~4.7%。结论 该方法稳定可靠,可用于测定铁棍山药皮中三个菲类化合物的含量,为铁棍山药的质量控制及其开发利用提供一定理论支持。
【Abstract】 Objective To determine the content of three phenanthrenes in the peels of Dioscorea opposita Thunb.cv.Tiegun by high performance liquid chromatography (HPLC).Methods ZORBAX Eclipse XDB C8 chromatographic column (5 μm,4.6 mm×150 mm) was used.The mobile phase was acetonitrile (A)-0.1% formic acid solution (B) with gradient elution (0~15 min,25%→30%A;15~45 min,30%→45%A).The flow rate was 1.0 mL·min-1.The detection wavelength was 260 nm.Results The three compounds showed good linearity (R2>0.999) in the concentration ranges of 0.02 to 0.12 mg·mL-1,with good precision,stability,and repeatability.The average recoveries of three phenanthrenes ranged 98.23%~106.02%,with RSDs of 2.4%~4.7%.Conclusion The method is stable and reliable,and can be used to determine the content of three phenanthrenes in the peels of Dioscorea opposita Thunb.cv.Tiegun.It provides a theoretical support for the quality control and development of Dioscorea opposita Thunb.cv.Tiegun.
