A new ester, armatuside (1), along with 13 known compounds (2-14), were obtained from the ethanolic extract of the heartwoods of Osmanthus armatus. The structures of all compounds were deduced using 1D, and 2D NMR spectroscopic methods. The absolute configuration of 1 was deduced by chemical correlation with a known compound. Compounds 2-14 were isolated from the plant for the first time.
