RESUMO
Four new triterpenoid saponins, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-11alpha-methoxy-23-hydroxylongispinogenin, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-11alpha-methoxy-23,29-dihydroxylongispinogenin, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-29-hydroxysaikogenin F and 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-saikogenin F, have been isolated from Atriplex semibaccata. The structures were determined primarily by NMR spectroscopy. The assignment of NMR signals was performed by means of 1H-1H COSY, ROESY, HMQC and HMBC experiments.
