Figure 1: High-performance liquid chromatography profiling of ursolic acid and oleanolic acid presented in the crude extracts of Lepechinia caulescens wild plant and callus tissues. Chromatographic conditions: C18 column (4.6 mm × 75 mm), methanol: acid water (H3PO4) 83:17 (v/v), flow rate of 0.9 mL/min, and 205 nm detection. L: Natural leaves; S: Natural stems
