摘要 [目的]建立同时测定六味地黄胶囊中马钱苷、芍药苷和丹皮酚3种成分含量的反相高效液相色谱法(RPHPLC)。[方法]以Waters ODS C18( 4.6 mm×250 mm,5 μm)柱为分析柱、甲醇-0.1%磷酸为流动相进行梯度洗脱,流速为1.0 ml/min,检测波长芍药苷和马钱苷为230 nm、丹皮酚为274 nm,柱温40 ℃。[结果]芍药苷在0.066 5~1.663 2 μg、马钱苷在0.107 9~2.697 7 μg、丹皮酚在0.122 4~3.060 0 μg范围内均具有良好的线性关系,相关系数(r)分别为0.999 4、0.999 8、0.999 9,平均回收率为芍药苷97.63%(RSD=0.82%)、马钱苷97.66%(RSD=0.74%)、丹皮酚96.22%(RSD=1.21%)。[结论]该方法简便、准确、重复性好,可用于六味地黄胶囊的质量控制。

Abstract [Objective] To establish RPHPLC method for simultaneous determining paeoniflorin, loganin and paeonol in Liuwei Dihuang Capsule. [Method] RPHPLC assay was carried out using a Waters ODS C18 (4.6 ×250 ,5 ) column.The mobile phase was consisted of methanol -0.1% phosphoric acid in gradient elution.The flow rate was 1.0 ml/min.The UV detection wavelength was set at 230 for paeoniflorin and loganin,and 274 for paeonol.The column temperature was 40 ℃. [Result] The linear ranges of paeoniflorin, loganin and paeonol were 0066 5-1.663 2 (r=0.999 4 ), 0.107 9-2.697 7 (r=0.9998 ), 0.122 4-3.060 0 (r=0.999 9 ), respectively. The average recoveries of paeoniflorin, loganin and paeonol were 97.63% (RSD was 0.82%) , 97.66% (RSD was 0.74%) , and 96.22% (RSD was 121%) , respectively. [Conclusion] The method is simple, accurate and reproducible. It can be used for the quality control of Liuwei Dihuang Capsule.

六味地黄胶囊是由滋阴补肾的经典代表方剂六味地黄丸改进制剂方法而成的,是《中国药典》2010版一部收載的常用复方制剂。六味地黄胶囊依然由熟地黄、酒萸肉、山药、牡丹皮、茯苓和泽泻六味中药组成,只是改进了制备方法,减少了服用量,易于保存和增加病人的依从性。所以六味地黄胶囊同样具有滋阴补肾的功效,可用于肾阴亏损、头晕耳鸣、腰膝酸软、骨蒸潮热、盗汗遗精的治疗[1]。喻箴等通过临床研究表明六味地黄胶囊总疗效明显优于传统剂型六味地黄丸[2];韦咏莲也通过临床研究发现六味地黄胶囊治疗2型糖尿病有助于控制血糖,减轻病情[3]。
2010版《中国药典》记载采用高效液相色谱法测定六味地黄胶囊中丹皮酚的含量,用薄层扫描法测定熊果酸的含量[1];迟富杰等采用HPLC法测定六味地黄胶囊中熊果酸含量[4-5]和丹皮酚的含量[6-7];水彩红等采用HPLC法测定六味地黄胶囊中马钱苷的含量[8-9]和芍药苷的含量[10]。……
