Lignans of Trachelospermum asiaticum. var. intermedium. V. Isolation of Nortrache1ogenin-4, 4'-di-O-β-D-glucopyranoside

Abstract

A new lignan diglucoside was isolated from the stems of Trachelospermum asiaticum NAKAI var. intermedium NAKAI (Apocynaceae) and its structure was established as nortrachelogenin-4, 4'-di-O-β-D-glucopyranoside (I). Also the presence of α-conidendrin glucoside was suggested.
