title: Two new sesquiterpenes from endophytic fungus S49 of Cephalotaxus hainanensis.
abstract: Two new sesquiterpenes, 10,11,12-guaianetriol (1) and 1,10,11,12-guaianetetrol (2), were isolated from endophytic fungus S49 of Cephalotaxus hainanensis Li. Their structures were determined based on HR-ESI-MS and spectroscopic techniques (1D and 2D NMR).
