Abstract Propolis has been used as indigenous medicine for curing numerous maladies. The one that is of ethnopharmacological use is stingless bee propolis from Tetragonula pagdeni . A simultaneous high-performance liquid chromatography (HPLC) investigation was developed and validated to determine the contents of bioactive compounds: 3-isomangostin, gamma-mangostin, beta-mangostin, and alpha-mangostin. HPLC analysis was effectively performed using a Hypersil BDS C 18 column, with the gradient elution of methanol–0.2% formic acid and a flow rate of 1 ml/min, at 25 °C and detected at 245 nm. Parameters for the validation included accuracy, precision, linearity, and limits of quantitation and detection. The developed HPLC technique was precise, with lower than 2% relative standard deviation. The recovery values of 3-isomangostin, gamma-mangostin, beta-mangostin, and alpha-mangostin in the extracts were 99.98%, 99.97%, 98.98% and 99.19%, respectively. The average contents of these mixtures in the propolis extracts collected from different seasons were 0.127%, 1.008%, 0.323% and 2.703% (w/w), respectively. The developed HPLC technique was suitable and practical for the simultaneous analysis of these mangostin derivatives in T. pagdeni propolis and would be a valuable guidance for the standardization of its pharmaceutical products.
