四种新的阿魏酸蔗糖酯,β-D-(1-O-乙酰基-6-O-反式-阿魏酸基)呋喃果糖基-a-D-2',6'-O-二乙酰吡喃葡萄糖苷(1),β-D-(1-O-乙酰基-6-O-反式-阿魏酸基)呋喃果糖基-a-D-2',4'-O-二乙酰吡喃葡萄糖苷(2),β-D-(6-O-反式-阿魏酸基)呋喃果糖基-a-D-2',4\',6'-O-三乙酰吡喃葡萄糖苷(3),β-D-(1-O-乙酰基-6-O-反式-阿魏酸基)呋喃果糖基-a-D-4',6'-O-二乙酰吡喃葡萄糖苷(4),从Sparganiumstoloniferum(Graebn。)布奇。-火腿.前Juz.通过化学证据和光谱分析阐明了它们的结构。化合物1~8对ADP诱导的血小板聚集有明显的抑制作用。
Four new ferulic acid sucrose esters, β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-2\',6\'-O-diacetylglucopyranoside (1), β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-2\',4\'-O-diacetylglucopyranoside (2), β-D-(6-O-trans-feruloyl)fructofuranosyl-a-D-2\',4\',6\'-O-triacetylglucopyranoside (3), β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-4\',6\'-O-diacetylglucopyranoside (4), together with four known phenylpropanoids (5-8) were isolated from the rhizome of Sparganium stoloniferum (Graebn.) Buch.-Ham. ex Juz. Their structures were elucidated by chemical evidence and spectral analysis. Compounds 1-8 exhibited obvious inhibitory effects on ADP-induced platelet aggregation.
