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( 4 ) the neat cement paste fluidity of copolymer would augment and the cohesiveness of cement would increase along with augmentation of pea dosage, but if the dosage was too big, the dosage of aa would be reduced, so it would reduce the carboxylic content of copolymer, and performance of water reduce would weaken, the dosage of pea23 can not more than 25 %. ( 5 ) the effect of water reduce would increase if the copolymer time increase
而與x40 ;比較，減水率、凝結時間、保坍性、抗壓強度比等綜合性能還有一定的差距，有待進一步的改進和研究。從合成pc23一6的工業性分析: pea23的酷化和pc23一6的共聚的放大試驗看，其混凝土試驗結果較為理想，且其合成工藝流程較為簡單，具備高分子的合成條件:而從經濟性分析， 30 % pc23一6水溶液的原料成本低於fdn ，其性能具有較大的優勢，具有廣闊的工業化的前景。
