Abstract:

A rapid and easy assay method for four triterpenoic acid isomers in Eriobotryae folium was established. The sample was extracted with methanol, then separated on a C30 column (250 mm×4.6 mm, 5 μm) at 20 ℃ using acetonitrile-water (95:5, v/v) as the mobile phase at a flow rate of 1.0 mL/min. The target compounds were simultaneously detected at 210 nm, and the injection volume was 10 μ L. The validation was carried out and the resolution (R≥2.2), the precision (RSD≤1.1%), the linearity (r≥0.9992), the repeatability (RSD≤4.4%), and the recovery (range from 95.4% to 101.7%, RSD≤4.8%) were acceptable. The method is reliable for the quantification of the four triterpenoic acid isomers by HPLC on C30 column.
