After every harvest, the C. asiatica plant material from both VIETGAP and ORGANIC fields were dried at 45-50 °C in an oven, until a humidity of 8 -10% is reached and then ground with ethanol/water (80:20 v/v) to obtain the total extract, which includes the free and glycosidic forms of the triterpenes. The total extract was hydrolysed with aqueous NaOH solution at reflux to obtain the total triterpenoic acids (madecassic, asiatic, and terminolic). HPLC analysis with an addition of βcyclodextrin to the mobile phase was used for the determination of the content of madecassic, asiatic and terminolic acid in the extracts before and after the alkaline hydrolysis of the ethanol/water extracts. With this HPLC method, the triterpenoic acids can be quickly and accurately identified and quantified ).
