| 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306 nm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. 631 9～1. 881 8 mg/L,高于干白葡萄酒中白藜芦醇的含量(0. 127 1～0. 255 9mg/L)。 |

| Abstract: |
| The content of resveratrol in wines was dedermined by HPLC.After being
ultrafiltrated (0. 45μm), 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 8mg·L-1, higher than that of white wine (0. 127 1～0. 255 9
mg·L-1). |
