为了测定红酒中鞣酸和白藜芦醇的质量浓度,确定红酒中关于“法兰西悖论”的主要功效物质,采用高效液相色谱法,对市售4种不同品牌红酒进行了质量浓度测定. 结果显示红酒中鞣酸质量浓度为0.81~1.44 mg/mL,白藜芦醇质量浓度为0.14~2.49 mg/L,鞣酸质量浓度比白藜芦醇高约103倍. 随着对鞣酸心血管活性药理学研究的不断深入,提示鞣酸也可能是解释“法兰西悖论”的主要功效物质.
To determine the content of tannic acid and resveratrol in red wine, and to identify the main functional substances in red wine about the “French paradox”, the high performance liquid chromatography(HPLC)was used to quantitative determine the contents of tannic acid and resveratrol in four different brands red wine. The results showed that the content of tannic acid in red wine was 0.81~1.44 mg /mL, and the content of resveratrol was 0.14~2.49 mg /L, that is to say, the content of tannin was about 103 times higher than resveratrol. Considering the more and more pharmacological studies on the cardiovascular activity of tannic acid, the results suggested that tannic acid may also be the main functional substance to explain the French paradox.
