摘要
为开发利用新疆葡萄,分析了新疆葡萄中生物活性物质的构成及其含量。采用超声法和回流法分别提取葡萄皮、籽中的齐墩果酸、白藜芦醇和原花青素,用高效液相色谱法和比色法分别测定葡萄皮、籽中齐墩果酸、白藜芦醇和原花青素的含量。葡萄中齐墩果酸主要存在于葡萄皮中,含量可高达1%左右,符合工业化提取要求;地产葡萄品种的齐墩果酸含量相对高于欧洲引进品种;齐墩果酸含量比较:人工发酵葡萄皮>自然发酵葡萄皮>新鲜葡萄皮。葡萄皮白藜芦醇的含量高于葡萄籽;欧洲引进葡萄品种白藜芦醇含量相对高于地产葡萄;白藜芦醇含量比较:人工发酵葡萄皮>自然发酵葡萄皮>新鲜葡萄皮>陈旧葡萄皮。葡萄籽原花青素含量高于葡萄皮;地产与欧洲引进葡萄品种的原花青素含量比较接近;原花青素含量比较:新鲜葡萄籽>自然发酵葡萄籽>人工发酵葡萄籽。由结果可以看出新疆葡萄富含齐墩果酸、白藜芦醇及原花青素等多种具有营养保健功能的生物活性物质。
The compositions and content of bioactive substances in Xinjiang grapes were analyzed. Oleanolic acid, resveratol and procyanidins were extracted from grape skins, grape seeds and waste residue of grape wineries by ultrasonic wave or reflux method, and then analyzed by high-performance liquid chromatographic method or colorimetric method. The content of oleanolic acid in grape skin was about 1% and satisfied the demands of industrial production. The content of oleanolic acid in the breeds of Xinjiang local grapes was higher than that in grapes introduced from Europe. When arranged in order of oleanolic acid content： the artificial fermented skin in waste residue from wineries 〉 the natural fermented skin in waste residue from wineries 〉 the fresh grape skin. The content of resveratol was higher in grape skins than in grape seeds and abundant in introduced Europe grapes than in Xinjiang local grapes. When arranged in order of resveratol content： the artificial fermented skin in waste residue from wineries 〉 the natural fermented skin in waste residue from wineries 〉 the fresh grape skin 〉 the stale grape skin. The content of procyanidins was higher in grape seed than in grape skin and similar between introduced Europe grapes and Xinjiang local grapes. When arranged in order of procyanidins content ： the fresh grape seeds 〉 the natural fermented seeds in waste residue from wineries 〉 the artificial fermented seeds in waste residue from wineries. Xinjiang grapes were rich in bioactive substances such as oleanolic acid, resveratol and procyanidins, which were beneficial to human health.
