[摘要]：Seven new compounds including three flavanone glycosides, visartisides A-C (1-3), three glycoside acyl esters, visartisides D-F (4-6), and one diphenylpropane glycoside. (4'-hydroxy-2',3',6',3 ''-tetramethoxy-1,3-diphenylpropane)-4 ''-O-beta-D-glucopyranoside (7), along with four known flavanone glycosides (8-11) were isolated from the leaves and stems of Viscum articulatum. The Structure elucidation Of 1-7 was based oil spectroscopic data analysis. Biological evaluation showed flat 1, 2, and 10 exhibited antioxidant activity using. a DPPH method and that compounds 1, 3, and 11 were active in a lipopolysaccharide-induced nitric oxide assay.
