Abstract

Garcinia mangostana fruit rinds contain high concentration of xanthones such as α-, and γ-mangostin. The α-mangostin-rich extracts have been used widely in nutritional supplements, herbal cosmetics and pharmaceutical preparations. This study aims to develop a reverse phase HPLC method for the quantification of α-, β- and γ-mangostin in G. mangostana fruit rind extracts. The method was validated at 244, 254, 316 and 320 nm. Selectivity was determined by comparing the retention time and the UV-Vis spectra of α-, β- and γ-mangostin in G. mangostana extracts with those of the reference compounds. Linearity was in the range 0.2 to 200 µg/ml at R2 > 0.9999. The intraday and interday precision was determined as a relative standard deviation, and was found to be (0.4±0.4) and (0.3 ± 0.3)%, respectively. The percentage recovery was in the range (96.3 ± 2.5) to (100.5 ± 3.4)%. The limits of detection and quantification were in the range 0.06 to 0.12 and 0.14 to 0.37 µg/ml, respectively. The reported method was applied for the determination of α-, β- and γ-mangostin concentration in 7 extracts of G. mangostana fruit rinds, and it could be considered as an important analytical tool for quality control, stability studies, pharmacokinetics, and standardization purposes.
