法测定炒蒲黄中3种黄酮苷元的含量 - 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
为了探讨玫瑰花抗氧化活性的影响因子，比较了不同干燥方法、提取方法对其抗氧化活性的影响，发现：经短时高温处理后再进行干燥有利于较好地保持玫瑰花的抗氧化活性；以水作溶剂提取时， 25 100范围内水提液的抗氧化活性随着温度的升高而增强；通过正交实验筛选得到常温下玫瑰花抗氧化活性物质的最佳提取方法为： 75乙醇为溶剂，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、正丁醇等有机溶剂进行两相分部萃取，发现玫瑰花的抗氧化活性物质主要存在于乙酸乙酯部，说明玫瑰花抗氧化活性主要成分可能是单宁类、黄酮苷类和原花色素类化合物； 4
