description

Three new triterpenoid saponins, 1-3, were isolated from the roots of Acanthophyllum squarrosum. Their structures were established mainly by 2D NMR techniques as 3-O-beta-D-galactopyranosyl-(1--2)-[beta-D-xylopyranosyl-(1--3)]-beta-D-glucuronopyranosyl-gypsogenin-28-O-beta-D-xylopyranosyl-(1--3)-beta-D-xylopyranosyl-(1--4)-beta-D-xylopyranosyl-(1--4)-3-O-acetyl-alpha-L-rhamnopyranosyl-(1--2)-3,4-di-O-acetyl-beta-D-fucopyranoside (1), 3-O-beta-D-galactopyranosyl-(1--2)-[beta-D-xylopyranosyl-(1--3)]-beta-D-glucuronopyranosyl-gypsogenin-28-O-beta-D-xylopyranosyl-(1--4)-alpha-L-rhamnopyranosyl-(1--2)-[5-O-acetyl-alpha-L-arabinofuranosyl-(1--3)]-4-O-acetyl-beta-D-fucopyranoside (2), and 3-O-beta-D-glucopyranosyl-quillaic acid-28-O-alpha-L-rhamnopyranosyl-(1--2)-alpha-L-arabinopyranosyl-(1--2)-[beta-D-glucopyranosyl-(1--6)]-beta-D-glucopyranoside (3).
