摘要
目的分析降香及其伪品挥发性成分的异同点,为降香的真伪优劣鉴别提供科学依据,并为降香的进一步研究提供参考。方法采用顶空固相微萃取法(HS-SPME)结合气质联用(GC-MS)技术对降香及其伪品挥发性成分进行分析鉴定,并用面积归一化法计算各成分的相对百分含量。结果共检测出70种成分,鉴定出38种成分,主要为烯类、醇类和醛酮类,从降香挥发性成分中检测出42个峰,鉴定出25个成分,占挥发性成分的96.54%;从其伪品中检测出28个峰,鉴定出19种成分,占挥发性成分的80.7%。结论降香及其伪品的挥发性成分差异较大,两者共有的成分有6种,含量差异大,降香的主要成分为橙花叔醇,占挥发性成分的61.47%,其伪品的主要成分为β-芹子烯,占总挥发性成分的59.04%。本实验为降香真伪优劣的鉴别提供科学指导,同时为降香的进一步开发提供参考依据。
Objective To analyze similarities and differences of volatile components of Dalbergiae Odoriferae Lignum（DOL） and its adulterants,so as to provide a scientific basis for the identification of the authenticity of the pros and cons of DOL,and offer the reference for the further study of DOL. Methods With headspace solid phase microextraction（HS-SPME）combined with gas chromatography-mass spectrometry（GC-MS）,volatile components of DOL and its adulterants were analyzed and identified,and the relative content of each component was calculated by area normalization method. Results There were 70 compounds detected,in which 38 compounds were identified. They were mainly alkenes,alcohols,aldehydes and ketones. A total of 42 compounds were de？tected from DOL volatile components,and 25 components were identified,accounting for 96.54% of the volatile components;28 peaks were detected from its adulterants,and 19 compounds were identified,accounting for 80.7%of the volatile components. Con？clusion There were huge differences in volatile components between DOL and its adulterants. Only 6 common components were de？fected both in the DOL and it＇s adulterants,with their quite different contents. The main component of DOL was nerolidol,accounting for 61.47%of volatile components;the main component of its adulterants was beta selinene,accounting for 59.04%of total volatile components. The present result provides a scientific guidance for the identification of true or false DOL and also a reference for the fur？ther development of Dalbergia wood.
