(-)-Catechin 및 배당체의 환원력 및 α-glucosidase저해 활성 = Reducing Power and α-Glucosidase Inhibitory profiles of (-)-Catechin and Its glycoside

다국어 초록 (Multilingual Abstract)

the EtOAc fraction of the MeOH extract of Ulmus davidiana, (-)-catechin (1), (-)-catechin-7-O-β-D-api-ofuranoside (2), and (-)-catechin-7-O-β-D- xylopyranoside (3) were isolated and characterized on the basis of 1H-and 13C-NMR,and FABMS spectral data. Compounds 1-3 showed more strong reducing power activities than α-tocopherol, a positive control.Key wordsUlmus davidiana, (-)-catechin, (-)-catechin-7-O-β-D-apiofuranoside, (-)-catechin-7-O-β-D-xylopyranoside,reducing power.... (Ulmus davidiana var. japonica). .. ...
