Secondary metabolites from the leaves of Feijoa sellowiana Berg.

Abstract

The investigation of the lipid extract of leaves of Feijoa sellowiana cultivated along the east coast of Sicily has yielded in addition to the widespread secondary metabolites: α-tocopherol, flavone, stigmasterol and β-carotene, an inseparable mixture of tyrosol esters of lignoceric ( 1a), cerotic ( 1b) and montanic ( 1c) acids, and a novel galactolipid identified as (2 S)-1,2,6′-tri- O-[(9 Z,12 Z,15 Z)-octadeca-9,12,15-trienoyl]-3- O-β- d-galactopyranosyl glycerol ( 2).
