不同海拔酿酒葡萄一年生枝条酚类物质含量的测定

         

摘要

为有效利用葡萄园中修剪产生的葡萄枝条,减少资源的浪费,获得高附加值的产品。以四川省横断山脉北麓不同海拔高度赤霞珠、美乐葡萄一年生枝条为材料,比较测定了其酚类物质的含量。结果表明,赤霞珠一年生枝条中共测得有8种单体酚,且随着海拔的升高,其中的表儿茶素、水杨酸、芦丁、绿原酸,香豆素5种酚类单体含量呈现先升高再降低的趋势;美乐一年生枝条共测得了9种单体酚,随着海拔高度的不断上升,枝条中的芦丁、山柰酚、咖啡酸、香豆素4类酚类单体物质均呈整体上升趋势,而桑色素、表儿茶素、槲皮素、绿原酸整体均是呈现下降的趋势。在总类黄酮方面,随着海拔升高,赤霞珠和美乐一年生枝条均呈增加的趋势,但是差异不显著;在原花青素方面,赤霞珠枝条呈现先减少后增加的趋势,而美乐枝条呈现先增加后减少的趋势。%In order to use effectively the waste branches from vineyard, the phenols content of annual wine grape branches from different altitudes in Hengduan mountains of Sichuan province were investigated as materials. The results showed that eight phenolic monomers were detected in annual branched of Cabernet Sauvignon, and the contents of epicatechin, salicylic acid, rutin, chlorogenic acid, coumarin showed firstly increase gradually, then decreased as the altitude rises. Nine phenolic monomers were detected in annual branches of Merlot, and the contents of rutin, kaempferol, caffeic acid, coumarin were increased as the altitude rises, the contents of morin, epicatechin, quercetin, chlorogenic acid showed decrease. Total flavonoid content in annual branches of Cabernet Sauvignon and Merlot showed the tendency of increase, but the differences were non-significant. The contents of proanthocyanidins in annual branches of Cabernet Sauvignon firstly decreased then increased, and firstly increased then decreased with altitude increase in annual branches of Merlot.
