A New Lignan Glucoside from the Whole Plants of Salvia Scapiformis

Phytochemical investigation of the whole plants of Salvia scapiformis Hance afforded eight compounds, including one new lignan, (+)-8 α-hydroxypinoresinol-8- O-[6′′- O-(4′′′-hydroxybenzoyl)]- β-d-glucopyranoside ( 1), four known lignans, (+)-8 α-hydroxy-pinoresinol-8- O- β-d-glucopyranoside ( 2), (+)-8 α-hydroxypinoresinol ( 3), (+)-pinoresinol ( 4), and (+)-medioresinol ( 5), and three known triterpenoids, ursolic acid ( 6), 4- epi-niga-ichigoside F1 ( 7), and niga-ichigoside F1 ( 8). Their structures were determined on the basis of extensive spectroscopic analyses and comparison with spectroscopic data in the literature. The absolute configuration of the new compound 1 was determined by chemical transformation and GC analysis.
