【 摘 要 】

From Portulaca oleracea which is widely distributed in Korea and has long been used as a folk medicine, two biophenolic glycosides, 3-hydroxy-1-(2-hydroxyethyl)phenyl-4-O-b-D-glucopyranoside (1) and 2-(3,4-dihydroxyphenyl) ethyl-O-b-D-glucopyranoside (2) were isolated using column chromatography and reversed-phase HPLC. 13C NMR spectral assignment for these compounds was revised by the extensive 2-D NMR experiments such as NOESY, HMQC, and HMBC. These compounds showed a considerable antioxidant effect in DPPH assay system.
