Another two diterpene dilactone glycosides, nagilactosides F and G were isolated from the polar fraction of Podocarpus nagi. Their structures were determined as 1-deoxy-nagilactone A-2α- O-β-D -glucopyranosyl - (1–3) -β-D-glucopyranosyl- (1–6) -β-D-glucopyranoside and 1-deoxy - nagilactone A-2α -O -β -D -glucopyranosyl - (1–6) - β - D -glucopyranosyl - (1–3)-β-D-glucopyranoside respectively by chemical and spectroscopic methods.
