摘  要:
基于气相色谱质谱联用技术对含瘤疤油梨木材进行鉴定,采用顶空进样方式,探究其主要特征峰及化学成分.结果表明,含瘤疤油梨主要有6个特征峰,出峰时间集中在20~25min之间;其主要化学成分为烯炔类物质,同时根据其主要特征峰构建对应的指纹图谱,为含瘤疤油梨准确快速鉴定提供理论基础..

摘  要:
Dalbergia odorifera(youli)with burl have been identified using headspace sampling method based on gas chromatography mass spectrometry technique,and its main characteristic peaks and the chemical compositions were explored aimed at providing the theoretical foundation for identification rapidly and accurately. Results showed that six main characteristic peaks existed in Dalbergia odorifera(youli),and the peak time concentrated between 20 ~25 min. Meanwhile its main chemical compositions were alkene and acetylene chemicals. Also,the fingerprint has been built according to its main characteristic peaks.
