HPLC에 의한 뽀리뱅이 플라본 배당체 화합물의 동시정량 = Simultaneous Quantitative Determination of Flavone Glycosides in Youngia japonica by High-performance Liquid Chromatography

다국어 초록 (Multilingual Abstract)

This research was attempted to determine the composition of flavone glycosides (luteolin 7-O-glucoside, luteolin 7-O-glucuronide, linarin) in addition to luteolin simultaneously in aerial part of Youngia japonica (Compositae) by high-performance liquid chromatography. The MeOH extract was further fractionated into the three parts, CHCl3 fraction,EtOAc fraction and BuOH fraction, to investigate the contents of the four flavones in the three fractions. The content of luteolin 7-O-glucuronide (10.07 mg/g) was highest in the MeOH extract among those of the flavones. These four compounds were observed to be less than 1.0 mg/g in CHCl3- and EtOAc fractions but relatively high in BuOH fraction.

국문 초록 (Abstract)

저자들이 국화과 식물의 플라보노이드 성분분석 연구 과정에서 뽀리뱅이(Y. japonica) 성분을 분석한 결과 luteolin,Lut-7-Glc, Lut-7-GlcU, linarin이 확인되며 그 중 Lut-7-GlcU가 10.07 mg/g MeOH extract 수준으로서 그 함량이 가장 높았다. 또, 이들 화합물은 CHCl3 분획과 EtOAc 분획 BuOH 분획 중 주로 BuOH 분획에 분포하는 것으로확인되었다. 따라서, 뽀리뱅이는 4종 플라본 화합물 중Lut-7-GlcU의 함량이 높으며, linarin이 낮은 함량으로관찰되는 식물로 특성화할 수 있었다.
