摘要
以丙酮、乙酸乙酯、85%乙醇作溶剂,用超声法提取诃子中的抗氧化成分。用ESR法检测香烟烟气自由基含量的变化。结果显示,85%乙醇作溶剂的得率最高(16.4%)。在香烟滤嘴和烟丝中分别添加50μL 0.2%诃子的3种提取物时,85%乙醇提取物对香烟烟气自由基的清除率最高(34.1%)。
The antioxidant of Terminalia chebula Rotz are distilled by the ultrasonic extraction method with acetone, ethyl acetate and 85% ethanol. The content of free radical in cigarette smoke is tested by electron-spin resonance（ESR） method. The results showed that the extract rate of 85% ethanol as solvent is the highest（ 16.4% ） . when 50μ L 0. 2% three extracts of Terminalia chebula Rotz were respectively added in filters and caporal of cigarette, the scavenging percentage of 85% alcohol extracts from Terminalia chebula Rotz is the highest（34. 1% ）.
