Chemical constituents from the fruit of Schisandra Chinensis.

A new 18-norschiartane bisnortriterpenoid, 12-angeloyl wuweizidilactone I (1) and nine known compounds, wuweizidilactone I (2), wuweizidilactone G (3), deoxychizandrin (4), sasanquin (5), orcinol-O-β-D-glucopyranoside (6), okanin-4-methyl ether-3'-O-β-Dglucopyranoside (7), evemic acid (8), juglansol A (9) and 2-acetoxybenzyl benzoate (10), were isolated from the fruits of Schisandra Chinensis. Their structures were established by a combination of spectroscopic data analysis in addition to comparison with literature data. Compound 1 was new, and compounds 6–10 were isolated from Schisandrae Chinensis for the first time. [ABSTRACT FROM AUTHOR]
