In order to study the influence factors of aoa of rose flowers, the effects of drying and extraction methods on the aoa of rose flowers were investigated. the results indicated that drying after high - temperature short - time pretreatment was rather effective to maintain their aoa ; the aoa of water extracts was stronger when the temperature was raised from 25 to 100 ; by using orthogonal test, the optimum extraction conditions of rose flowers were : solvent - 75 % ethanol ; ratio of material and solven - 1 : 10 ; extraction times - three times with 24 h at one time, at the room temperature. the extracts obtained by 75 % ethanol were fractionatedly extracted with petroleum, diethyl ether, ethyl acetate and n - butanol in turn, and the various fractions " aoa were analyzed
為了探討玫瑰花抗氧化活性的影響因子，比較了不同乾燥方法、提取方法對其抗氧化活性的影響，發現：經短時高溫處理后再進行乾燥有利於較好地保持玫瑰花的抗氧化活性；以水作溶劑提取時， 25 100范圍內水提液的抗氧化活性隨著溫度的升高而增強；通過正交實驗篩選得到常溫下玫瑰花抗氧化活性物質的最佳提取方法為： 75乙醇為溶劑，液料比1 ： 10 ，提取3次，每次24h ； 75乙醇提取物依次用石油醚、乙醚、乙酸乙酯、正丁醇等有機溶劑進行兩相分部萃取，發現玫瑰花的抗氧化活性物質主要存在於乙酸乙酯部，說明玫瑰花抗氧化活性主要成分可能是單寧類、黃酮苷類和原花色素類化合物； 4
