摘要/Abstract

摘要： 用剂量3.6 kJ·m^-2的紫外线C（Ultraviolet C，UV-C）辐射处理‘京蜜’葡萄成熟果实，25 ℃条件下避光孵育24 h后，控制温度为25 ℃和0 ℃贮藏，贮藏后0、0.5、1、2、3、7、10、14、24、34 d取样，HPLC法分析果皮白藜芦醇（Resveratrol，Res）及其糖苷含量。结果表明：UV-C辐射后25 ℃条件下孵育24 h能显著提高反式白藜芦醇（trans-Resveratrol, trans-Res）和顺式白藜芦醇苷（cis-Piceid, cis-PD）的含量，不能提高反式白藜芦醇苷（trans Piceid，trans PD）含量。贮藏温度对UV-C辐射葡萄果皮Res及其糖苷含量具有重要影响。无论是对照果实还是UV-C辐射处理果实，果皮中均未检测到顺式白藜芦醇（cis-Resveratrol, cis-Res）。25 ℃和0 ℃贮藏条件下对照果皮(trans-Res trans-PD、cis-PD含量低，变化幅度很小，而UV-C处理果皮中变化幅度很大，绝大部分时间显著高于对照。

Abstract:

The mature fruits of post-harvest ‘Jingmi’grape were irradiated by the dosage of 3.6 kJ·m^-2ultraviolet C (UV-C) and then incubated 24 hours in dark at 25 ℃. The UV-C irradiated berries and control berries were stored at 0 ℃ and 25 ℃. The berries was sampled at 0, 0.5, 1, 2, 3, 7, 10,14, 24 and 34 d. Resveratrol and piceid content in grape berries was determined by HPLC. The results showed: Trans-resveratrol (trans-Res) and cis-Piceid (cis-PD) content in grape berries skin was significantly increased when treated by UV-C irradiation and then incubated 24 h in dark at 25 ℃, but trans-Piceid (trans-PD) content in grape berries skin was not significantly increased. Storage temperature played an important role on the level of Res and its glycosides by UV-C irradiation treatment. cis-Resveratrol (cis-Res)could not detected in skin of UV-C irradiated berries and control berries.trans-Res, trans-PD and cis-PD content of control grape berries skin was low and stable under 25 ℃ and 0 ℃, while UV-C irradiated berries skin was higher than control at mostly sampling time and changed sharply.
