The structure of the tetrasaccharide unit of camellidins, saponins possessing antifungal activity
Abstract
By successful application of recently developed 1H n.m.r. techniques, the structure of the tetrasaccharide unit of camellidin-I (1) and -II (2), saponins having antifungal activity, was elucidated as β-D-glucopyranosyl-(1→2)-β-D-galactopyranosyl-(1→4)-[α-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranoside, without degradation of the glycosidic linkages.
