Chemical constituents from Abies ernestii var.salouenensis

Thirteen compounds were isolated from the branches and leaves of Abies ernestii var. salouenensis by silica gel, Sephadex LH-20 and ODS column chromatographies. Their structures were identified by physicochemical properties and spectral techniques as(7S, 8S)-3-methoxy-3′, 7-epoxy-8, 4′-oxyneoligna-4, 9, 9′-triol( 1 ), isomassonianoside B( 2 ), 8, 8′-dihydroxypinoresinol( 3 ), shikimic acid n-butyl ester( 4 ), 4-hydroxy benzoic acid( 5 ), shikimic acid( 6 ), caffeic acid( 7 ), hexacosyl ferulate( 8 ), benzoic acid( 9 ), apigenin-8-C-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside( 10 ), syringetin-3-O-rutinoside( 11 ), 5-hydroxy-3, 4′, 7-trimethoxyl flavone( 12 ), 4′, 5-dihydroxy-3, 7-dimethoxy-6-methyl flavone( 13 ). All compounds were isolated from this plant for the first time, and compounds 1 - 4 , 6 , 10 - 12 were isolated from this genus for the first time.
