Chromone Glycosides and Hepatoprotective Constituents of Hypericum erectum

다국어 초록 (Multilingual Abstract)

Two chromone glycosides, hyperimone A [7-(β-D-glucopyranosyloxy)-5-hydroxy-2-(1-methylethyl)-4H-1-benzopyran-4-one (1)] and hyperimone B [7-(β-D-glucopyranosyloxy)-5-hydroxy-3-methyl-4H-1-benzopyran-4-one (2)], together with six known compounds were isolated from the methanolic extract of the whole plant of Hypericum erectum. 1,3,5,6-Tetrahydroxyxanthone
(5) and I3, II8-biapigenin (6) showed moderate hepatoprotective activity with EC50 values of 160.2 ± 0.6 μM and 217.7 ± 1.3 μM, respectively, against tacrine-induced cytotoxicity in HepG2 cells.
