基于GC-IMS对不同花期金银花挥发性成分的对比分析
Comparative analysis of volatile components of honeysuckle at different flowering periods based on GC-IMS
摘要
Abstract
Objective To identify the volatile components of honeysuckle and compare the differences in volatile components among samples at different flowering stages.Methods Gas chromatography-ion mobility spectrometry(GC-IMS)was used to analyze the volatile organic compounds in honeysuckle samples at different developmental stages.The OPLS-DA analysis method was employed to screen representative differential characteristic components.A systematic study was conducted on five varieties of honeysuckle at five different flowering stages.Results A total of 72 volatile compounds were detected by GC-IMS.The silver flower stage and the golden flower stage contained rich components such as benzaldehyde dimer,and some components(such as benzaldehyde monomer,trans-2,4-heptadienal monomer,etc.)gradually increased with development.The OPLS-DA results showed a clear distinction among honeysuckle samples at different flowering stages,and 28 differential characteristic components were screened out,including cis-3-hexenol monomer,n-hexanol monomer,cis-3-hexenol dimer,etc.Conclusion For the first time,the similarities and differences of volatile components in different flowering stages and varieties of honeysuckle were quickly and comprehensively presented,and the 28 volatile components screened out could be distinguished as their characteristic components.关键词
