Sterols and triterpenes from Gundelia tournefortii L. var Armata
Chemical investigation of the dichloromethane extract of the the edible young stems of Gundelia tournefortii L. var Armata yielded β-sitosteryl-3β-glucopyranoside-6-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 fa...
