摘要:目的 建立HPLC同时测定三果汤水提物中没食子酸、柯里拉京及鞣花酸含量的方法。方法 采用Agilent ZORBAX SB-C18色谱柱(4.6 mm×250 mm,5 ?m),流动相为乙腈-0.1%磷酸水溶液,梯度洗脱,检测波长为260 nm,柱温30 ℃,流速为1.0 mL/min。结果 没食子酸、柯里拉京及鞣花酸3种成分有较好的基线分离,且峰形较好,分别在0.174~2.61 ?g、0.04~0.60 ?g、0.052~0.78 ?g范围内线性关系良好;平均加样回收率分别为99.98%、99.81%、100.12%,RSD均小于2.0%。结论 本方法快速、准确、重复性好,可为三果汤水提物的质量控制提供依据。

Abstract: Objective To establish an HPLC method for the simultaneous determination of contents of gallic acid, corilagin and ellagic acid in aqueous extract from Sanguo Decoction. Methods The analysis was carried out on an Agilent C18 column (4.6 mm × 250 mm, 5 ?m), and the mobile phase was composed of acetonitrile and 0.1% phosphoric acid aqueous with gradient elution. The detection wavelength was 260 nm. The flow rate was 1.0 mL/min at column temperature of 30 ℃. Results Gallic acid, corilagin and ellagic acid were completely separated and the peak shape was good. It showed a good linearity in the concentration range of 0.174–2.61 ?g, 0.04–0.60 ?g, and 0.052–0.78 ?g, respectively. The average recoveries of gallic acid, corilagin and ellagic acid were 99.98%, 99.81% and 100.12%, respectively. The RSD were less than 2.0%. Conclusion This method is rapid, accurate and repeatable, which can provide references for the quality control of Sanguo Decoction.

三果湯由诃子、毛诃子、余甘子3味药组成,为藏医学的重要基础方,具有清热、调和气血、化解坏血功效[1]。《四部医典》称其“主治瘟疫,紊乱热症,促使热症成型”。研究表明,三果汤主要含鞣质酚酸类成分,具有抗氧化、降糖调脂、抗病原微生物、抗炎、抗肿瘤等多种药理作用[2-3]。诃子与毛诃子均为使君子科植物的干燥成熟果实。有报道,二者活性成分均为以没食子酸为主的鞣质类物质,并对诃子中没食子酸含量进行了测定[4-7]。而鞣花酸则在植物界中

广泛分布,在诃子中含量较高,有报道将鞣花酸作为诃子的质控指标[8-9]。余甘子为大戟科叶下珠属植物的干燥成熟果实,有机酸类物质是其主要成分[10-12],2015年版《中华人民共和国药典》规定以没食子酸为指标评价余甘子质量。目前有较多报道增加了多酚类成分柯里拉京作为余甘子的质控指标[13]。
中药及其制剂质量标准的研究与建立已由单一成分向多种成分甚至有效物质群发展。……
