摘要
Abstract
Simultaneous distillation and extraction was applied to handle cigarette mainstream smoke particles,and fractions containing megastigrnatrienone were prepared using Semi-preparation HPLC.Contents and odor threshold values of megastigmatrienone in tobacco smoke were determined by GC-MS/O respectively,and odor active values (OAV) were obtained.Results showed that:1) Odor threshold value of four isomers of megastigmatrienone was 0.81 ng/Ml,2.05 ng/mL,3.86 ng/mL and 0.88 ng/mL respectively.2) OAVs of four isomers of megastigmatrienone were in the order of megastigmatrienone d (75.58) ＞ megastigmatrienone b (35.35) ＞ megastigmatrienone a (23.01) ＞ megastigmatrienone c (2.36).3) Odor threshold values of flavoring substances which possessed unstable chemical properties or several isomers could be determined accurately by using GC-MS/O technology,and hence the odor active values (OAV) in the cigarette smoke.The technology boasted accurate determination of OAVs of flavoring substances compared with traditional methods.关键词
