Phytochemical investigation on the concentrate of Huangjing wine, resulted in the isolation of three new tyrosol derivatives 4-hydroxyphenethyl 2-(R)-hydroxy-3-phenylpropionate (), 4-hydroxyphenethyl(4-hydroxy-3-methoxyphenyl)propionate () and 4-hydroxyphenethyl ethyl succinate (), together with 5 known compounds, ferulic acid (), L-phenyllactic acid (), hydroxytyrosol (), dihydroferulic acid (), cyclo(L-Pro-D-Tyr) (). 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 exhibited obvious antioxidant effect, and new compounds and exhibited medium antioxidant effect.
黄精酒浓缩液的植物化学研究,分离得到三个新的酪醇衍生物:4-羟基苯乙基 2-(R)-羟基-3-苯丙酸酯()、4-羟基苯乙基(4-羟基-3-甲氧基苯基)丙酸酯()和 4-羟基苯乙基丁二酸酯(),以及 5 种已知化合物:阿魏酸()、L-苯乳酸()、羟基酪醇()、二氢阿魏酸()、环己基(L-Pro-D-Tyr)()。它们的结构通过光谱分析和与文献数据的比较来阐明。所有化合物在 DPPH(2,2-二苯基-1-苦基肼)自由基中均显示出抗氧化作用。其中,新化合物 表现出明显的抗氧化作用,新化合物 和 表现出中等的抗氧化作用。
