The leaf Perilla is of specific aroma and of biological activitie. The similarities and differences of the volatile organic compounds in the fresh leaves of P. frutescens (NMZS), P. frutescens var. frutescens (BS) and P. frutescens var. frutescens (ZS) were studied. Solid phase microextraction (SPME) was used to enrich and extract the volatile compounds. The volatile components were isolated and identified by GC-MS. The volatile components were significantly different in three Perilla plants. The three plants could be clustered into a single group by principal component analysis. The high matching (≥90%) and relatively high content (≥2%) volatile componets of three plants were different. The high matching and high content compounds of NMZS were 3,7-dimethyl-2,6-octadienal, (Z)- 3,7- dimethyl-2,6-octadienal, 1-octen-3-ol etc., while those of ZS were α-caryophyllene, β-caryophyllene, apiol etc., and those of BS were β-caryophyllene, 1-octen-3-ol, 3,7-dimethyl-1,6-octadien-3-ol etc. A total of 19 specific volatile components were fould in NMZS (3,7-dimethyl-2,6-octadienal, (Z)-3,7-dimethyl-2,6-Octadienal etc.), eight in BS (Apiol etc.), and six in ZS (3,7-dimethyl-1,6-octadien-3-ol and so on). Common volatiles were also found, which were β-elemene, germacrene D, β-caryophyllene and 1-octen-3-ol. Cluster analysis result showed that BS and ZS could be clustered into one group, while NMZS was clustered into another group. The study would provide a basis for the further development and utilization of Perilla plants.
