芫荽茎叶精油成分及清除DPPH自由基能力研究
Study on Chemical Constituents of Coriander Leaf Essential Oil and Scavenging Capacity Against the DPPH Radical
【摘要】 以乙醚为溶剂,采用索式萃取法萃取新鲜芫荽茎叶,以0.252%产率获得芳香精油。利用GC-MS分析仪对精油进行了分析,检测出60种成分,解析了占精油94.200%的41种成分,其中,酯类化合物57.755%,烷烃类化合物11.300%,醛类化合物16.168%,芳香族化合物8.077%。该精油对DPPH(1,1-D:phenyl-2-picrylhy-drazyl)自由基的清除率最高达62.7%,水蒸气蒸馏获得精油的清除率为84.2%。
【Abstract】 The essential oil was obtained from the fresh aerial parts of coriander(Coriandrum sativum L.) by the method of Soxhlet’s extraction with 0.252% yield and the oil was analyzed by GC-MS.A total of 60 constituents were detected,among them,41 compounds identified accounting for 94.200% of the total.Esters are the most abundant which was up to 57.755%,and hydrocarbons was 11.300%.Aldehydes and aromatic compounds was 16.168% and 8.077%,respectively.The scavenging capacity of essential oils was studied against the DPPH(1,1-Diphenyl-2-picrylhydrazyl) radical,the result indicated that the maximum scavenging rate was 62.4% and water steam distillation could reach up to 84.2%
