RESUMO

Phytochemical investigation on the concentrate of Huangjing wine, resulted in the isolation of three new tyrosol derivatives 4'''-hydroxyphenethyl 2-(R)-hydroxy-3-phenylpropionate (1), 4'''-hydroxyphenethyl(4'-hydroxy-3'-methoxyphenyl)propionate (2) and 4''-hydroxyphenethyl ethyl succinate (3), together with 5 known compounds, ferulic acid (4), L-phenyllactic acid (5), hydroxytyrosol (6), dihydroferulic acid (7), cyclo(L-Pro-D-Tyr) (8). Their structures were elucidated using spectroscopic analysis and by comparison with the literature data. All compounds displayed antioxidant effect in the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical. Among them, the new compound 2 exhibited obvious antioxidant effect, and new compounds 1 and 3 exhibited medium antioxidant effect.
