Abstract

[Objective] To establish the determination method of oleanlic acid in Shuganling(dispersing the stagnated liver-QI)capsules using HPLC.[Methods] The determination was carried out on ODS column(4.6 mm×250 mm,5 μm)with mobile phase of methol-0.2% phosophoric acid(85:15)and detection wave-length at 210 nm.[Results] The oleanolic acid sample showed a good linear relationship at the range of 0.304～2.432 μg and the average recovery rate was 98.73%.RSD was 0.33%.The recovery is 98.3%.[Conclusions] The method is simple,accurate,reproducible and can be used for content determination of oleanolic acid in this preparation.
