Abstract

This study was performed to analyze aroma pattern of Panax species (Korean Panax ginseng C.A. Meyer, Chinese Panax ginseng C.A. Meyer, Panax quinquefolium L, and Panax notoginseng F.H. Chen) by the PHGC (potable handheld gas chromatograph). Ratios of several peak areas in chromatogram of derivative parrtern were as follows. If ratio of Korean Panax ginseng was 1, Panax notoginseng was $0.030{\sim}0.674$, Chinese Panax ginseng was $0.005{\sim}0.212$ and panax quinquefolium was $0.241{\sim}0.871$. Ratios of peak area at $Rt_{20.02}$ were that if Korean panax ginseng was 1, Chinese Panax ginseng was 0.212, Panax quinquefolium was 0.343 and Panax notoginseng was 0.065. Ratios also of peak area at $Rt_{21.70}\;and\;Rt_{24.90}$ showed clear difference among aroma patterns of Panax specie cultivars. Flavor component at $Rt_{26.15}$ was not detected in Panax quinquefolium and Panax notoginseng but in Korean Panax ginseng and Chinese Panax ginseng. Ratios of peak area at $Rt_{26.15}$ were that if Korean Panax ginseng was 1, Chinese Panax ginseng was 0.185. And so habitat of Panax species cultivars was discriminated. Cultivar and habitat of dried panax species was remarkably distinguised by the chromatogram of frequency pattern, derivative pattern and visual pattern using olfactory images known as Vapor $print^{TM}$.

분말상태의 인삼속 식물들의 품종 및 원산지를 판별하기 위하여 SAW 센서가 내장된 PHGC를 이용하여 향기 패턴을 분석하였다. 한국 백삼을 1로 기준할 때 전체적인 Rt에 대한 frequency pattern의 면적비는 화기삼 $0.248{\sim}0.871$, 전칠삼 $0.030{\sim}0.674$, 중국산 백삼 $0.005{\sim}0.212$ 범위로 나타났다. 분명한 차이를 나타내는 몇 개의 특정 향기성분의 면적비를 보면 $Rt_{20.02}$에서 한국산 백삼 1일 때, 중국산 백삼 0.212, 화기삼 0.343, 전칠삼 0.065이었다. 또한 $Rt_{21.70}$$Rt_{24.90}$에서 검출되는 향기성분의 면적비도 품종간의 차이가 뚜렷하였다. 한국산 백삼과 중국산 백삼에서 검출된 Rt_26.15 향기성분의 면적비는 각각 1과 0.185로 나타나 원산지간의 차이도 분명히 나타났다. $Rt_{26.15}$의 향기성분은 화기삼과 전칠삼에서는 검출되지 않았다. Frequency pattern, derivative pattern을 Vapor $print^{TM}$을 사용하여 도형화하여 비교한 결과 한국 백삼(Korean Panax ginseng C.A. Meyer), 화기삼(미국삼, 서양삼, Panax quinquefolium L.), 전칠삼(Panax notoginseng F.H. Chen), 중국산 백삼(Chinese Panax ginseng)은 서로 다른 패턴을 보여주어 품종간의 차이는 물론 원산지의 차이도 뚜렷하게 나타났다.
