摘要
本文采用反相液相色谱法测定蜂王浆及其制品中10-HDA的含量。色谱柱为KromasilC18柱,流动相为V(甲醇):V(水):V(磷酸)=55:45:0.2,流速1.0ml/min,对羧基苯甲酸乙酯作内标,检测波长210nm。本法简单、快速、准确,重现性好,回收率高(97.6%～101.8%)。
The contents of 10-hydroxy-2-decenoic acid in royal jelly and its products were determinded by RP-HPLC. 10-HDA could be separated on C18 column by using CH3OH-H2O-H3PO4 ( 55:45:0.2, V/V/V) as the mobile phase at a flow-rate of 1.0ml/ min,Ethyl-P-hyaroxybenzoate was used as the internal standard and then detected at UV 210 nm ,This method was simple, rapid and accurate, the results were reproducible. The recoveries were 97.6%～101.8%.
