Abstract
Phytochemical investigation on the leaves of Rabdosia serra led to the isolation of two new abietane diterpenoids, raserranes A (1) and B (2), and four known phenylpropanoids (3–6). Their structures were determined by spectroscopic data. Compound 1 represented the rare examples of abietane diterpenoids featuring a 16-methoxycarbonyl group.
