실험 절차
Hydrolysis of corilagin with 0.1N HCl was performed for 1 hr and the solution was chromatographed over Sephadex LH-20 using (H2O -MeOH, 10:0-3:7) to give ellagic acid (1H-NMR in DMSO-d6 : δ 7.45, 2H, s), gallic acid (1H-NMR in acetone-d6 : δ 7.14, 2H, s) and glucose (Rf=0.45, cellulose plate, n-BuOH:pyridine:H2O=6:4:3, under aniline hydrogen phthalate spray as brown spot)
