Abstract
The present study was carried out to isolate and identify of antioxidants from makgeolli. Makgeolli (3 L) was
filtered and the residue was extracted by MeOH. The combined filtrates and MeOH extracts were successively solventfractionated
by n-hexane, EtOAc, and BuOH. In the antioxidative activity against DPPH and ABTS+ radicals of each
fraction obtained after solvent-fractionation, EtOAc and BuOH layers showed higher activities than other fractions.
Therefore, the two layers were respectively purified by column chromatography and HPLC. The isolated compounds were
subjected to NMR and MS analyses and identified as 4-hydroxybenzaldehyde (1, 2.0 mg), 2-(4-hydroxyphenyl)ethanol (2,
tyrosol, 15.3 mg), trans- and cis-ferulic acids (3 and 4, 1.2 mg), 1H-indole-3-ethanol (5, tryptophol, 3.4 mg), dimethyl
succinate (6, 14.9 mg), succinic acid (7, 7.4 mg), and mono-methyl succinate (8, 7.8 mg). The presence of 1-5 in makgeolli
have never before been reported.
