Abstract
Seven novel saponins were isolated from a bark extract of Quillaja saponari a Molina, the compounds were characterized, using mainly NMR spectroscopy, mass spectrometry and chemical methods, as quillaic acid substituted at C-3 with oligosaccharides consisting of various compositions of D-glucuronic a cid D-galactose, D-xylose, and L-rhamnose and at C-28 with complex oligosac charide structures consisting of various compositions of D-xylose, L-rhamno se, D-apiose and a branched 4-O-acetyl-D-fucose residue.
