Pheonolic Compounds from the Fruits of Viburnum sargentii Koehne
AbstractSeven phenolic compounds were isolated from the fruits of Viburnum sargentii Koehne by silica gel column chromatography and preparative HPLC. On the grounds of chemical and spectroscopic methods, their structures were identified as (−)-Epicatechin (1), 5,7,4′-trihydroxy-flavonoid-8-C-β-D-glucopyranoside (2), 1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-α-L-rhamnopyranoxypropyl)-2-methoxyphenoxy]-1,3-propane-diol (erythro) (3), 1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-α-L-rhamnopyranoxypropyl)-2-methoxyphenoxy]-1,3-propanediol (threo) (4), (R)-4-hydroxylphenol O-(6-O-oleuropeoyl)-β-D-glucopyranoside (5), (R)-3-methoxy-4-hydroxylphenol O-(6-O-oleuropeoyl)-β-D-glucopyranoside (6), quercetin-3-O-rutinoside (7). Compounds 5 and 6 are new monoterpene phenolic glycosides, compounds 1, 3 and 4 were isolated from the Viburnum genus for the first time, and compounds 2 and 7 from the Viburnum sargentii Koehne for the first time. Compounds 1–7 were also assayed for their antioxidant activities with DPPH free radicals. View Full-Text
