摘要:

以7个玫瑰品种干燥花蕾为试验材料,采用DPPH法、水杨酸法、邻苯三酚自氧化法、鳌合金属离子法测定供试材料的抗氧化性,并利用隶属函数法对供试材料抗氧化能力进行综合评价,为玫瑰的开发与利用提供理论参考。结果表明,各玫瑰品种的铁离子还原力都在70%以上,其中最高的是‘苦水’玫瑰(99.33%),最低的是‘和田重瓣红’玫瑰(77.66%);‘墨红’玫瑰羟基自由基清除率显著高于其他供试品种,‘法兰西’玫瑰(33.62%)和‘苦水’玫瑰(31.42%)显著低于其他品种;‘苦水’玫瑰的超氧阴离子清除率最高(82.13%),‘长白山重瓣红’玫瑰最低(26.53%),其他介于两者之间;各品种DPPH清除率均在90%以上,且彼此之间差异不显著,‘法兰西’玫瑰DPPH清除率最高(94.56%),‘苦水’玫瑰DPPH清除率最低(93.72%)。利用隶属函数法对供试玫瑰品种抗氧化性进行综合评价,抗氧化能力由高到低为‘墨红’玫瑰>‘苦水’玫瑰>‘金边’玫瑰>‘长白山重瓣红’玫瑰>‘法兰西’玫瑰>‘和田重瓣红’玫瑰>‘平阴’玫瑰。

Abstract:

To provide theoretical reference for the development and utilization of rose varieties, we used dry buds of seven rose varieties as the materials, and determined the antioxidant capacity of the tested materials by DPPH method, salicylic acid method, pyrogallol autoxidation method and chelating metal ion method. Then the antioxidant capacity of the materials was evaluated comprehensively by membership function method. The results showed that the ferric ion reducing power of all tested materials was more than 70%. The highest was found in Rosa rugosa ‘Kushui’ (99.33%), and the lowest was found in R. damascena ‘Hetian’ (77.66%). The scavenging rate of OH-· of R. ‘Crimson Glory’ was significantly higher than that of other tested varieties, and that of ‘France’ rose (33.62%) and R. rugosa ‘Kushui’ (31.42%) were significantly lower than that of other varieties. The scavenging rate of superoxide anion of R. rugosa ‘Kushui’ was the highest (82.13%), and that of Rosa rugosa Plena in Changbai Mountain was the lowest (26.53%), and that of the other varieties was between the above two. The DPPH clearance rate of all varieties was above 90%, and there was no significant difference among the varieties. The DPPH clearance rate of ‘France’ rose was the highest (94.56%), and that of R. rugosa ‘Kushui’ was the lowest (93.72%). The antioxidant activity of the tested materials was evaluated comprehensively by membership function method. The antioxidant capacity from high to low was: R. ‘Crimson Glory’> R. rugosa ‘Kushui’> R. forrestiana ‘Jinbian’> R. rugosa Plena in Changbai Mountain > ‘France’ rose> R. damascena ‘Hetian’ > ‘Pingyin’ rose.

Key words: Rosa rugosa, dry flower buds, antioxidant capacity, membership function method, comprehensive evaluation
