[Objective]To research on the volatile chemical components in the seeds of Perilla frutescens(L.)Britt.,and to provide scientific references for their development and utilization.[Methods]Solid phase micro-extraction(SPME)technology was used to extract the volatile chemical components from P.frutescens seeds.And the volatile chemical components were analyzed by GC-MS.[Results]A total of 60chromatographic peaks were isolated.And 47 chemical components were identified,accounting for 89.73%of the total content of volatile components.The main components were octanoic acid(8.94%),caproaldehyde(8.31%),nonyl aldehyde(6.27%)and(E,E)-3,5-octadien-2-one(5.19%).[Conclusions]P.frutescens seeds were rich in volatile chemical components;and SPME-GC/MS method could obtain the component information rapidly and comprehensively.
