摘　　要：以延药睡莲(Nymphaea stellata)花瓣为原料,采用同时蒸馏萃取法(simultaneous distillation extraction,SDE)从中提取精油,再通过气相色谱-质谱(gas chromatography-mass spectrometry,GC-MS)手段鉴定精油中的主要化学成分,并对精油的体外抗氧化性进行初步研究。结果表明,NaCl含量、蒸馏时间、料液比皆会影响延药睡莲精油的含量,最佳提取率为0.101%。延药睡莲精油主要成分为羰基类化合物如2-十七烷酮等;延药睡莲精油具有一定的体外抗氧化性,但是抗氧化性要比2,6-二叔丁基对甲酚(2,6-Di-tert-butyl-4-methylphenol,BHT)弱。Essential oil from Nymphaea stellata was extracted by simultaneous distillation,GC-MS method was used to identify the main chemical constituents in essential oil,and a preliminary study on the antioxidant activity of essential oil. The results showed that Na Cl content,distillation time and material liquid ratio could affect the essential oil content of Nymphaea stellata,and the best extraction rate was 0.101 %. The main components of essential oil were carbonyl compounds,such as 2-Heptadecanone,etc. Essential oil content of Nymphaea stellata had antioxidant activity in vitro,but its antioxidant activity was weaker than that of BHT.
