【摘要】 从羽叶鬼灯檠 (RodgersiapinnataFranch .)的根茎中分离得到 6个单萜二糖苷 ,它们的结构通过波谱方法分别鉴定为 :(E ) 3,7 dimethyl 1 O [α L rhamnopyranosyl (1→ 6 ) β D glu copyranosyl] oct 2 en 7 ol (1) ,(E ) 3,7 dimethyl 1 O [α L arabinofuranosyl (1→ 6 ) β D glucopy ranosyl] oct 2 en 7 ol (2 ) ,geranyl 1 O α L arabinofuranosyl (1→ 6 ) β D glucopyranoside (3) ,gera nyl 1 O α L rhamnopyranosyl (1→ 6 ) β D glucopyranoside (4 ) ,geranyl 1 O β D xylopyranosyl (1→6 ) β D glucopyranoside (5 ) ,geranyl 1 O α L arabinopyranosyl (1→ 6 ) β D glucopyranoside (6 )。其中化合物 1为新化合物 ,单萜二糖苷类化合物系首次在该属中发现。更多还原

【Abstract】 From the rhizomes of Rodgersia pinnata,six monoterpene disaccharide glycosides were isolated and their chemical structures were determined as (E)-3,7-dimethyl-1-O-[α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranosyl]-oct-2-en-7-ol (1),(E)-3,7-dimethyl-1-O-[α-L-arabinofuranosyl-(1→6)-β-D-glucopyranosyl]-oct-2-en-7-ol (2),geranyl-1-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (3),geranyl-1-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (4),geranyl-1-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (5),geranyl-1-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (6) by spectral methods.Among them,compound 1 is a new monoterpene disaccharide glycoside.It is the first time that monoterpene disaccharide glycosides were isolated from the genus Rodgersia.更多还原
