Abstract
Investigation of the constituents from the stem barks of Garcinia multiflora has yielded two new compounds, multiflorabiphenyl A (1) and 24-p-E-coumaroyl-tetracosanyl (E)-ferulate (2), along with 10 known compounds, friedelin (3), friedelan-3β-ol (4), α,β-amyrin (5), rheediachromenoxanthone (6), 1,7-dihydroxyxanthone (7), 9-hydroxycalabaxanthone (8), oblongifoliagarcinine B (9), 1,24-tetracosandiol diferulate (10), 30-epi-cambogin (11), and guttiferone F (12). The structures of these compounds were determined by detailed spectroscopic methods including HR-ESI-MS and 1D and 2D NMR.
