【Abstract】 Ten known compounds were isolated from the ethanolic extract of the roots of Cynanchum komarovii Al.Iljinski.(Asclepiadaceae)collected in Ningxia Hui Autonomous District. Their structures were determined by spectroscopic analysis to be β D fructofuranosyl (2→1) α D [6 O sinapoyl] glucopyranoside(1),β D (3 O sinapoyl) fructofuranosyl (2→1) α D [6 O sinapoyl] glucopyranoside(2),[6 O β D glucopyranosyl (1→6) β D glucopyranosyl 1,2 bis O (4 hydroxy 3,5 dimethoxycinnamoyl)([STFZ]3),7 demethoxytylophorine(4),9 hydroxylinalool 3 O β D xylopyranosyl (1→6) β D glucopyranoside(5),(2 E,6R ) 2,6 dimethyl 2,7 octadiene 1,6 diol(6),[(+) syringaresinol](7),4′ O demethylepiyangambin(8),4′ hydroxy 2′ methoxyl acetophenone(9),( 2S,3S,4R,12E) N [2′ ( R ) hydroxydocosanoate] 1,3,4 trihydroxy 2 amino eicosanoate 12 ene(10).Except for compounds 4 and 9,,the other eight compounds were first reported from this plant.更多还原
