Abstract

Two new sesquiterpenoids, named dalodorin A (1) and dalodorin B (2), together with four known sesquiterpenoids, were isolated from the heartwood of Dalbergia odorifera. Their structures were elucidated on the basis of spectroscopic analysis including 1D and 2D NMR techniques and HR-ESI-MS. Evaluation of the isolated compounds for cytotoxicity against two human cancer cell lines (Hela and HepG-2) showed moderate activities (25.22–60.45 μM).
