| Popis: | Phytochemical investigation of the whole plants of Salvia scapiformis Hance afforded eight compounds, including one new lignan, (+)-8α-hydroxypinoresinol-8-O-[6''-O-(4'''-hydroxybenzoyl)]-β-d-glucopyranoside (1), four known lignans, (+)-8α-hydroxy-pinoresinol-8-O-β-d-glucopyranoside (2), (+)-8α-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. |
