中文摘要：
本实验用不同剂量的紫外光（UV-C和UV-B）对采后葡萄进行照射处理,并于不同的暗处理时间收集葡萄果皮,采用HPLC法分析其中白藜芦醇的含量。结果表明：UV-B对白藜芦醇的诱导作用不是很大,用UV-C照射20min暗处理48h后,白藜芦醇含量可提高15倍以上,鲜重达到155μg/g。因此可以考虑采用UV-C照射处理采后葡萄,把其作为高白藜芦醇含量的食物源。
英文摘要：
The effects of UV fights （UV-C and UV-B）on the radiation of resveratrol in the harvested grape peelings were examined. The resveratrol content was analyzed by HPLC. The results showed that UV-B has little effects on the content of resveratrol in grape peelings, whereas maximum resveratrol content （15-fold higher than untreated grapes） is achieved when irradiated 20 rain with UV-C with 48 h darkness treatment. Therefore, the controlled UV-C irradiation pulses are useful as a simple postharvest treatment to obtain possible ＂functional＂ grapes with a dietary source of high resveratrol content.
