【摘要】 本文采用顶空固相微萃取和气相色谱质谱联用(HS-SPME-GC-MS)技术比较分析了连翘花蕾和花的挥发性成分。从连翘花蕾和花中共鉴定了83个化合物,其中40个化合物是共有的。连翘花蕾的挥发性成分以烃类(41.04%)为主,而连翘花的挥发性成分以醇、醛和酮类化合物(26.46%)为主;酯类化合物在花蕾中的含量为8.11%,在花中下降到2.12%;而酸类化合物则从3.56%上升到5.18%。结果表明,随着花蕾的开放,酯类成分逐渐被水解为酸。更多还原

【Abstract】 The volatile constituents from the buds and flowers of Forsythia suspense were analyzed by head-space solid phase microextraction,coupled with GC-MS.Eighty-three compounds were identified from the buds and flowers of F.suspense,and 40 compounds were mutual.Hydrocarbons(41.04%) were the main constituents in the buds and alcohols,aldehydes and ketones(26.46%) were dominant in the flowers.Esters decreased from 8.11% in buds to 2.12% in flowers,and acids increased from 3.56% in buds to 5.18% in flowers.It indicated that esters were hydrolyzed into acids with blooming.更多还原
