Chemical Constituents of Trichilia hirta (Meliaceae)

Abstract

A novel oleanane-type triterpene, 15-chloro-β-amyrone (1), was isolated from Trichilia hirta, together with the known compounds taraxer-3-one (2) and β-taraxerol (3), along with two novel esters, 3-(isobutyryloxy)-2,2,4-trimethylpentyl palmitate (4) and 3-(isobutyryloxy)-2,2,3-trimethylpentyl stearate (5), and the known 3-hydroxy-2,2,4-trimethylpentyl isobutyrate (6). These compounds were characterized on the basis of their spectroscopic and HRSEIMS data and by comparison with literature data.
