Abstract

국내산과 중국산 시판 홍삼 농축액의 원산지 판별을 위하여 LC-MS/MS의 data를 통계 처리해 보았다. 국내산 시판 홍삼 농축액과 중국산 시판 홍삼 농축액은 LC-MS/MS의 ginsenoside 함량 비교 결과 특정 ginsenoside에서 함량 차이를 크게 보여주었고, 이를 토대로 의심시료를 선정할 수 있었다. 또한, LC-MS/MS data를 정준 판별 분석과 주성분 분석을 통하여 원산지가 의심되는 시료를 검출할 수 있었고, 그 혼합 비율까지 추정할 수 있었다. The geographical origin of commercial red ginseng concentrate was studied using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The ginsenoside content of domestic and Chinese red ginseng concentrates was determined. Four types of suspected origin samples could be selected this technique. The LC-MS/MS data were statistically analyzed on the basis of canonical function analysis and principal component analysis. Domestic and Chinese samples could be discriminated via canonical function analysis using posterior probability. In addition, the mixture ratio (Korean or Chinese origin) of the unknown origin specimen could be predicted based on the relationship between the mixing concentration of red ginseng concentrates and principal component 1.
