摘要
从云南产蝉翼藤 ( Securidaca inappendiculata)茎的乙醇提取物中分离得到 3个蔗糖酯类成分 .采用化学方法和现代光谱分析技术 (包括 UV,IR,ESIMS,FABMS,1 D和 2 D NMR等 )鉴定其结构分别为β-D-( 3,4 -O-disinapoyl) fructofuranosyl-α-D-( 6 -O-sinapoyl) glucopyranoside( 1 ) ,β-D-( 3-O-feruloyl) fructofura-nosyl-α-D-( 6 -O-sinapoyl) glucopyranoside( 2 )和 β-D-( 3-O-feruloyl) fructofuranosyl-α-D-( 6 -O-feruloyl) gluco-pyranoside( 3) .其中 ,化合物 3为新的阿魏酸蔗糖酯 ,命名为蝉翼藤糖酯 A( Securoside A) .
Three sucrose esters, β-D-(3,4-O\%-disinapoyl)fructofuranosyl-α-D-(6-O-sinapoyl)gluco-pyranoside(1), β-D-(3-O-feruloyl)fructofuranosyl-α-D-(6-O-sinapoyl)glucopyrano-side(2), and β-D-(3-O-feruloyl) fructofuranosyl-α-D-(6-O-feruloyl)glucopyranoside(3) were isolated from the stems of Securidaca inappendiculata collected from Yunnan Province. Among them, compound 3 was a new sucrose ester and was named as securoside A . All structures were elucidated on the basis of chemical and spectroscopic evidence, especially 13C, 1M NMR and ESI-MS experiments.
