국화(C. morifolium)품종인 ‘백마’ 줄기를 80% MeOH 수용액으로 3회 반복 추출한 뒤, 감압농축한 추출물을 EtOAc, n-butyl alcohol과 H₂O층으로 계통분획을 실시하였다. EtOAc분획에 대하여 SiO₂ 및 ODS column chromatography를 반복실시하여 2종의 지방산 화합물을 분리 및 정제하였다. Nuclear magnetic resonance, infrared spectrometry, FAB-MS, GC-MS data를 해석하여, 화합물 1과 2를 각각 (2S)-1-O-β-D-galactopyranosyl-2,3-dilinoleoylglycerol과 (2S)-1-O-β-D-galactopyranosyl-2,3-dipalmitoylglycerol로 구조동정 하였다.

The stem of Chrysanthemum morifolium, ‘Baekma’, were repeatedly extracted with 80% aqueous MeOH and the concentrates was partitioned into ethyl acetate (EtOAc), n-butyl alcohol and H₂O fraction. The repeated silica gel and octadecyl silica gel column chromatographies for the EtOAc fractions led to isolation of two glycosyl glycerides. The chemical structures of the compounds were determined as (2S)-1-O-β-D-galactopyranosyl-2,3-dilinoleoylglycerol (1) and (2S)-1-O-β-D-galactopyranosyl-2,3-dipalmitoylglycerol (2) based on spectroscopic data anlyses including nuclear magnetic resonance, mass sperctrometry, and infrared spectrometry and gas chromatography mass spectrometry.
