文摘建立了一种可同时测定11种酚类物质的高效液相色谱(HPLC)法,并对枣果中的酚类物质进行了分析测定。色谱条件为:Waters Symmetry C_(18)柱(4.6 mm×150 mm,5μm),流动相为甲醇和磷酸水(pH 2.6),280 nm和320 nm双波长紫外检测,柱温30℃,进样量5μL,流速0.6 mL/min,梯度洗脱程序:0 min 15%A,15～25 min 25%A,65 min 75%A,70 min 15%A,梯度线性变化。经测定,新鲜梨枣果内中含有儿茶素、表儿茶素、没食子酸、原儿茶酸、绿原酸和芦丁等酚类物质,其中儿茶素和表儿茶素占检测到的酚类物质总量的85%以上,未成熟果含量远高于成熟果。
