Xanthones and polyisoprenylated benzophenones (PIBs) are two significant classes of plant secondary metabolites with a wide range of bioactivities. Garcinia species synthesize numerous xanthones and PIBs. Till now no method available claiming simultaneous identification and quantification of three xanthones, α-mangostin, β-mangostin, γ-mangostin, and two PIBs, xanthochymol, isoxanthochymol. Methodology & Theoretical Orientation: A validated ultra-HPLC (UHPLC)- photodiode array (PDA) method for the simultaneous identification and quantification of five compounds in different extracts of eight Indian Garcinia species was developed. The compounds were separated on a Waters ACQUITY™ UPLC H-Class column using a mobile phase consisting of solvents 0.1% formic acid in water (A) and methanol (B) in gradient elution mode. The total run time was 9 min. Conclusion & Significance: From fruit rinds of eight Indian Garcinia species, namely Garcinia cambogia, G. cowa, G. indica, G. loniceroides, G. mangostana, G. morella, G. pedunculata, and G. xanthochymus, extracts were prepared using solvents of varying polarity.
