摘要
采用硅胶、ODS和葡聚糖凝胶LH-20柱层析方法,从大叶紫珠(马鞭草科)70%乙醇提取物的乙酸乙酯萃取部位得到一个新的苯丙素类衍生物。采用包括电喷雾离子化高分辨质谱和一维、二维核磁共振等多种光谱学手段鉴定该化合物结构为2-甲氧基对苯二酚-4-O-[(5-O-反式-咖啡酰)-β-D-呋喃芹菜糖]-(1→2)-β-D-吡喃葡萄糖苷。
A new phenylpropanoid derivative was isolated from EtOAc fraction of 70% ethanol extract of Callicarpa macrophyUa Vahl (Verbenaceae) with various chromatographic methods on silica gel, ODS and Sephadex LH-20 eohmms. Its structure was identified to be methoxyquinol 4-0- [ (5 -O-trans-p-eaffeoyl) -β-D-apiofuranosyl- ( 1→2 ) -β-D-glucopyr- anoside] (1) by extensive spectroscopic methods,including HR-ESI-MS, 1D and 2D NMR.
