[HPLC determination of oleanolic acid and llrolic acid in Chinese medicinal herbs].
OBJECTIVE
To develop a new method for simultaneous determination of oleanolic acid and llrolic acid in Chinese medicinal herbs at the same time.


METHODS
HPLC was carried out on a Shim-pack CLC-ODS column using MeOH-H2O-HOAc-TEA (83:17:0.04:0.02).


CONCLUSIONS
The average recovery of oleanolic acid and llrolic acid was 103.3 +/- 2.07% and 102.7% +/- 0.65% respectively.
