Two New Lactones from Cephalotaxus fortunei var. alpnia

Two New Lactones from Cephalotaxus fortunei var. alpnia

Two new lactones, fortunolides A (1) and B (2), together with three known compounds, hainanolidol,32 acetylcephalotaxine, and wilsonine, were isolated from the needles and stem of Cephalotaxus fortunei. Their structures were elucidated on the basis of MS and NMR data.
