  9. 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
