Abstract

The first monoterpene-based meroterpenoid (1) and two novel sesquiterpene-based ones (2 and 3) with unprecedented skeletons were isolated from the leaves of Psidium guajava. Their structures with absolute configuration were elucidated by extensive spectroscopic studies. A plausible biosynthetic pathway for all meroterpenoids from the title plant is also proposed. Compounds 2 and 3 showed significant cytotoxicity toward HepG2 and HepG2/ADM cells.
