Three diterpene dilactone glycosides from Podocarpus nagi.
Three water-soluble constituents, nagilactosides C-E, were isolated from Podocarpus nagi. Their structures were determined by chemical and spectroscopic methods, respectively. Nagilactoside C was identified as 1-deoxy-nagilactone A-2 alpha-O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranoside, nagilactoside D as 1-deoxy-nagilactone A-2 alpha-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside, and nagilactoside E as nagilactone A-1 beta-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyransoide.
