Abstract

Abstract: Guajadials C-F (1-4), four sesquiterpenoid-based meroterpenoids with unprecedented skeletons were isolated from the leaves of Psidium guajava. Their structures and relative configurations were established by extensive spectroscopic analysis. A possible biosynthetic pathway for 1-4 was also proposed.

Key words: Psidium guajava, meroterpenoid, guajadial
