Abstract

This study was conducted to find the appropriate fiber for extraction of volatile compounds from Perilla frutescens var. acuta. by solid phase microextraction (SPME). Two SPME fiber, carboxen/polydimethylsiloxane (CAR/PDMS) and polydimethylsiloxane (PDMS) were used to determine the selectivity of the fibers to the different flavor compounds present in the Perilla frutescens var. acuta. Thirty-nine compounds were identified in the volatile compounds extracted by CAR/PDMS fiber, including 6 aldehyde, 1 alcohol, 10 hydrocarbons, 17 terpene hydrocarbons, 2 ketones and 3 benzenes. In PDMS fiber, 3 aldehydes, 2 alcohols, 13 terpene hydrocarbons and 2 miscellaneouses were identified. Perillaldehyde was found to be major volatile flavor component of fresh Perilla frutescens var. acuta. Perillaldehyde and terpene hydrocarbons were more identified in PDMS fiber. These results suggested that the selectivity of PDMS fiber was better than that of CAR/PDMS fiber in Perilla frutescens var. acuta..

우리나라의 고유한 향신료로 활용되고 있는 소엽의 휘발성 향기성분 분석에 적합한 solid phase microextraction(SPME) fiber를 선정하기 위하여 carboxen/polydimethylsiloxane(CAR/PDMS)과 polydimethylsiloxane(PDMS)의 2종류 fiber를 이용하여 향을 추출한 후 GC/MS로 분석하였다. CAR/PDMS fber에 소엽의 향을 흡착시켜 분석한 결과, 39종의 성분이 확인되었으며, PDMS fiber를 이용하였을 때는 20가지의 향기성분이 확인되었다. 특히 PDMS fiber를 사용하였을 때 CAR/PDMS fber를 이용하였을 때 보다 perillaldehyde (40.50%), limonene (27.32%), E,E-,${\alpha}-famesene$ (10.22%) 및 ${\beta}-caryophyllene$ (8.02%)의 소엽의 주요 향기성분이 선택적으로 많이 확인되었다. 따라서 방향성 식용식물인 소엽의 향기를 SPME법으로 추출할 때는 PDMS fiber가 적합하다고 판단된다.
