摘　　要：果实酚类物质质量分数及其组分是酿造优质葡萄酒的重要基础。以山西乡宁地区的‘赤霞珠’(Cabernet Sauvignon)、‘梅鹿辄’(Merlot)为供试品种,从盛花后到果实成熟连续采样分析果皮和种子内酚类物质的变化规律,为实施优质酿酒葡萄栽培技术奠定基础。结果表明:葡萄果实在发育过程中呈现单"S"曲线;种子与果皮内总酚、单宁及总类黄酮质量分数均逐渐下降,但在采收前略有升高,种子内质量分数明显高于果皮内;在果实成熟过程中,果皮内花色苷总量呈现先上升后下降的趋势;不同品种之间,酚类物质变化趋势有较大差异。Phenolic compounds play a critical role in determining the high quality of wine.The changes of phenolic content in skin and seeds of Vitis vinifera varieties（Cabernet Sauvignon,Merlot）grapes in Xiangning,Shanxi province during the whole growth period were evaluated by spectrophotometric analysis,which will provide the theoretical foundation for reasonable cultivation technology.The results were shown as follows,the development of grape fruit was a single＂S＂-type curve.Overall,the mass fraction of total phenolics,tannin and total flavonoid in skins and seeds gradually decreased with the development of grape berry,with the exception increase slightly before harvesting,and their mass fraction in seeds were significantly higher than in skins.The accumulation of total anthocyanins in skins presented an up-and-down trend during fruit ripening.There was various trends for phenolics mass fraction among different grape varieties.
