Abstract

This study was carried out to improve the analysis method of gingerol compounds from ginger (Zingiber officinale Roscoe). Pungent components of ginger were extracted by acetone and lisolated by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) with LiChrosorb RP-18 column. Three homologues of gingerols were identified by HPLC-mass spectrometry (LC/MS) and nuclear magnetic resonance (NMR). The contents of [6]-, [8]- and [10]-gingerols in three homologues identified were 635.3 mg%, 206.6 mg% and 145.7 mg% in raw ginger, and were 418.2 mg%, 142.6 mg% and 103.3 mg% in ginger paste, respectively.

본 연구에서는 생각의 매운맛을 주요성분인 gingerol 화합물의 분석방법을 개선할 목적으로, 원료 생각을 아세톤으로 추출한 후 그 추출물을 TLC 및 LiChrosorb RP-18 column으로 장착된 HPLC를 사용하여 3가지 gingerol 동족체 화합물을 분리하였고, LC/MS 및 NMR로 확인한 결과 생강의 동족체 화합물은 [6]-, [8]-, [10]-gingerol로 확인되었다. 본 방법으로 추출한 gingerol 표준품을 사용하여 시판 원료생강 및 생각 페이스트 중의 gingerol 함량을 측정한 결과, 전자의 경우 [6]-, [8]-, [10]-gingerol 함량은 635.5 mg%, 206.6 mg%, 145.7 mg%이었고, 후자의 경우는 418.2 mg%, 142.6 mg%, 103.3 mg%로 각각 구성되어 있었다.
