采用微波法从大瓣玫瑰花蕾和小瓣玫瑰花蕾中提取黄酮类化合物,并测定了黄酮含量,分别为71.4736mg/g、71.0636mg/g,RSD(n=9)分别为0.5972%、0.5852%。利用了Fe2+-H2O2-罗丹明B分析体系,研究了两种玫瑰花蕾提取物清除羟自由基能力,实验结果表明,两种玫瑰花蕾提取物都具有较强的清除·OH的能力。
Flavonoids were extracted from petals rosebuds and petals rosebuds by microwave method and their flavonoids contents were determined as 71.4736mg / g and 71.0636mg / g, respectively. RSD (n = 9) were 0.5972% and 0.5852% . The Fe2 + -H2O2-Rhodamine B system was used to study the ability of two rose buds to scavenge hydroxyl radicals. The experimental results show that both rose bud extracts have a strong capability of scavenging OH radicals.
