Chemical Constituents from Acorus tatarinowii

Eighteen compounds were isolated from the rhizome of Acorus tatarinowii.Their structures were identified by spectroscopic data as(7S,8R)-4,9′-dihydroxyl-3,3′-dimethoxyl-7,8-dihydrobenzofuran-1′-propylneolignan(1),(7S,8R)-4,9′-dihydroxyl-3,3′-dimethoxyl-7,8-dihydrobenzofuran-1′-propylneoligan-9-O-β-D-glucopyranoside(2),7′-hydroxylariciresinol-9-acetate(3),5-hydroxy-3,7,4′-trimethoxyflavone(4),rhoifolin(5),astragalin(6),pinocembrin-7-O-rutinoside(7),kaempferol-3-O-rutinoside(8),rhodionin(9),isoschaftoside(10),5-hydroxymethyl-2-furaldehyde(11),trans-cinnamic acid(12),3,7-dihydroxy-11,15,23-trioxo-lanost-8,16-dien-26-oicacid(13),3,7-dihydroxy-11,15,23-trioxo-lanost-8,16-dien-26-oic acid methyl ester(14),cycloartenol(15),daucosterol(16),lupeol(17),(22E,24R)-ergosta-5,7,22-trien-3β-ol(18).Except for compounds 4,11,and 16,all the other substances were obtained from this plant for the first time.
