摘要：

Investigation of the green fruits of Clusia paralicola (Clusiaceae) led to the isolation and characterization of two 3,8 ''-biflavonoids, 2R, 35, 2 '' R, 3 '' R-GBI-7 ''-O-beta-glucoside (1) and 2R, 3S, 2 '' R, 3,8 ''-binaringenin-7 ''-O-beta-glucoside (2), together with four known compounds: beta-sitosterol, stigmasterol, beta-amyrin, and epicatechin. The structures were established from the IR, LC-ESI-MS and NMR spectral data, including 2D-NMR experiments. The absolute configurations of 1 and 2 were determined by CD spectra. The total extract and the biflavonoids demonstrated significant antioxidant activity in DPPH, ABTS, and beta-carotene/linoleic acid tests.
