Abstract

Two new neolignans, dolominol A (1) and dolominol B (2), together with 12 known Lignans, erythro-(7S,8R)-guaiacyl-glycerol-β-O-4'-dihydroconiferyl ether (3), threo-(7R,​8R)-1-​(4-​hydroxy-​3-​methoxyphenyl)​-​2-{4-[(E)-​3-​hydroxy-​1-​propen​yl)​]-​2-​methoxyphenoxy}-1,​3-​propanediol (4), (-)-dihydrodehydrodiconiferyl alcohol (5), (-)-massoniresinol (6), vladinol D (7), syringaresinol (8), prinsepiol (9), medioresinol (10), (+)-pinoresinol (11), 2α-guaicyl-4-oxo-6α-catechyl-3,7-dioxabicyclo [3.3.0]octane (12), cycloolivil (13), isolariciresinol (14) were isolated from Dolomiaea souliei (Franch.) C.Shih. Their structures were determined by UV, CD, HR-ESI-TOFMS, 1 D and 2 D NMR experiments. Their hepatoprotective effect against LPS-induced L-02 cells injury was also studied. Result revealed that compound 4 showed best protective effect on LPS-induced L-02 cells.
