Chemical investigation of the dichloromethane extract of the the edible young stems of Gundelia tournefortii L. var Armata yielded β-sitosteryl-3β-glucopyranoside-6̾-O-fatty acid esters (1); mixtures of β-sitosterol (2a) and stigmasterol (2b) in a 1:2 ratio; phytyl fatty acid esters (3a), α-amyrin fatty acid esters (3b); lupeol fatty acid esters (3c) and β-amyrin fatty acid esters (3d) in a 3:2:2:1 ratio; α-amyrin (4a) and β-amyrin (4b) in a 1:3 ratio; oleic acid (5a) and linoleic acid (5b) in a 1:2 ratio; and long-chain fatty alcohols (6). The structures of 1-6 were identified by comparison of their NMR data with literature data.
