摘　　要：为研究木棉Bombax ceiba 鲜花的挥发性成分,采用顶空固相微萃取-气相色谱-质谱联用法(HS-SPME-GC-MS)进行鉴定分析。通过GC-MS,采用面积归一法从木棉花中鉴定了56 个主要组分及其相对含量。结果表明,主要组分为模菲(13.74%)、(1R,3aS,5aS,8aR)-1,3a,4,5a 四甲基-1,2,3,3a,5a,6,7,8-八氢环戊二烯并[c]环戊二烯(10.95%)、2-亚甲基-4,8,8-三甲基-4-乙烯基-双环[5.2.0]壬烷(10.36%)等。其中萜烯类化合物占55.24%,烷类化合物占29.72%,还有少量的醛类、酮类和酯类化合物。The volatile components of Bombax ceiba flower were analyzed by HS-SPME-GC-MS method. Fifty-six volatile organic compounds were identified by GC-MS and their relative contents were also calculated by area normalization method. It was found that the main volatile components of B. ceiba flower were Modephene (13.74%),(1R,3aS,5aS,8aR)-1,3a,4,5a-tetramethyl-1,2,3,3a,5a,6,7, 8-octahydrocyclopenta[c]pentalene (10.95%) and 2-methylene-4,8,8-trimethyl-4-vinyl-bicyclo[5.2.0] nonane (10.36%). Among these components, terpene and alkyl compounds were accounted for 55.24%, 29.72%, respectively, as well as small quantities of aldehyde, ester and ketone constituents. The results of this study could provide an experimental basis for development and utilization of B. ceiba flower.
