Two new sesquiterpenoids with glycosides from the leaves and stems of Schisandra chinensis (Turcz.) Baill

Abstract

Two previously undescribed glycosidic bisnorsesquiterpenoids A − B (1 − 2), together with two known compounds (3 − 4), were isolated from the leaves and stems of Schisandra chinensis. Their structures were elucidated by extensive spectroscopic data (1D, 2D NMR, and HRESIMS). The anti-inflammatory activity, ABTS+ radical scavenging activity, and DPPH radical scavenging activity of compounds 1 − 4 were tested. However, all of these compounds showed only weak anti-inflammatory or antioxidant effects.
