摘要
在磷酸二氢钠-乙酸钠-硼酸钠溶液中,齐墩果酸有一灵敏的二阶导数极谱峰,峰电位为E_p=-1.600V(vs、SCE),线性范围为2.0×10^(-5)~1.0×10^(-3)mol/L,检测下限为10^(-7)mol/L。该方法操作简单、灵敏,可用于实际样品测定。
In this paper, a polarography method has reported for analyzing oleanolic acid in samples. The oleanolic acid gives a sensitive second derivative polarographic wave which range of linearity between 2.0×10-5-1.0×10-3mol/L in sodium dihydrogan phosphate - sodium acetate - boric acid sodium, and its detection limit is 5 × 10 -4 mol/L. The method has applied successfully to the analysis of oleanolic acid for drug.
