摘要
采用高效液相色谱（ＨＰＬＣ）法测定葡萄酒中白藜芦醇（Ｔ－ＲＥＳＶＥＲＡＴＲＯＬ）的含量。葡萄酒样品经０．４５μｍ超滤后可直接进样测定；采用乙晴－水流动相进行１∶９～９∶１梯度洗脱，在波长３０６ｎｍ下检测。试验结果表明，供试酒样中干红葡萄酒中白藜芦醇含量为０．６３１９～１．８８１８ｍｇ／Ｌ，高于干白葡萄酒中白藜芦醇的含量（０．１２７１～０．２５５９ｍｇ／Ｌ）。
The content of resveratrol in wines was dedermined
by HPLC.After being ultrafiltrated (0.45 μm),the wine samples were gradiently eluted by
acetonitrile water from 1∶9-9∶1.Then the content of resveratrol was detected under 306
nm.The results showed that among the wine samples,the resveratrol content in red wine was 0.
631 9￣1.881 8 mg·L -1 ,higher than that of white wine (0.127 1￣0.255 9 mg·L -1 ).
