Sesquiterpene lactones from Inula confertiflora A. Rich (Asteraceae) Leaf

Abstract

This study was aimed at the isolation of compounds present in the methanol extract of the leaves of the Ethiopian endemic plant Inula confertiflora A. Rich (Asteraceae). Phytochemical study on this extract led to first-time isolation and structural elucidations of reportedly bioactive sesquiterpene lactones, namely 4α, 5α-epoxyinuviscolide, graveolide, and carabrone, using spectroscopic methods.
