Three new terpenoids, opaciniols A-C (1-3), were isolated from the barks of Garcinia opaca, together with malabarica-17,21-dien-3β,14-diol (4) and 13βH-malabarica-14,17,21-trien-3β-ol (5). Their structures were determined on the basis of NMR spectroscopic data. 3 and 4 showed moderate cytotoxicity against HL-60 cells.
