摘要
以新疆野苹果(Malus sieversii)30个单株的成熟果实为试材,对果实多酚物质的组成、含量及遗传多样性进行了研究,结果表明:新疆野苹果30个单株多酚物质含量存在广泛的遗传变异,变异系数均在36.12%以上,遗传多样性极为丰富;鉴定出原花青素、没食子酸、绿原酸、对羟基苯甲酸、儿茶素、表儿茶素、香草醛、阿魏酸、苯甲酸、根皮苷、槲皮素、肉桂酸、根皮素等13种多酚物质,其中原花青素、表儿茶素、根皮苷和绿原酸是野苹果的主要多酚组分,总酚及主要多酚物质含量显著高于栽培苹果(Malus domestica)品种红星。
Experiments were conducted in ripened fruits of Malus sieversii obtained from 30 seedlings to study composition, content and genetic diversity of phenolic compounds. The results indicated that variation coefficients of phenolic compounds in M. sieversii seedlings were more than 36. 12%, which revealed wider variation range and rich genetic diversity. Proanthocyanidin, gallic acid, chlorogenic acid, ρ-hydroxybenzoic acid, catechin, epicatechin, vanillin, ferulic acid, benzoic acid, phloridzin, quercetin, cinnamic acid, phloretin were identified in the study, in which proanthocyanidin, epicatechin, phloridzin and chlorogenic acid existed in high concentraions. Comparision of phenolic compound contents in M. sieversii with those in M. domestica showed that total phenolic compounds and main constituents in M. sieversii were higher than that in M. domestica significantly.
