Psidguajones A and B, a pair of complex meroterpenoid epimers from the leaves of Psidium guajava†
Abstract
Psidguajones A and B, a pair of dimeric sesquiterpene-based meroterpenoid epimers, have been isolated from the leaves of Psidium guajava for the first time. Their structures were confirmed by comprehensive spectroscopic techniques combined with a comparison of experimental and calculated ECD data.
