In an attempt to study the chemical constituents from the twigs and leaves of Flueggea virosa, a new terpenoid, 9(10→20)-abeo-ent-podocarpane, 3β,10α-dihydroxy-12-methoxy-13- methyl-9(10→20)-abeo-ent-podocarpa-6,8,11,13-tetraene (1), as well as five known compounds were characterized. Their structures were elucidated on the basis of spectroscopic analysis. In addition, the structure of dehydroc...
