摘　　要：从白蔹Ampelopsis japonica(Thunb.)Makino的乙酸乙酯提取物中分离出5个单宁化合物。经光谱分析和化学方法鉴定,它们为没食子酸(gallic acid,1),1,2,6-三氧-没食子酰基-β-D-吡喃葡萄糖(1,2,6—tri-O-galloyl-β-D-glucopyranoside,2),1,2,3,6-四氧-没食子酰基-β-D-吡喃葡萄糖(1,2,4,6-tetra-O-galloyl-β-D-glucopyranoside,3),1,2,4,6-四氧-没食子酰基-β-D-吡哺葡萄糖(1,2,4,6-tetra-O-galloyl-β-D-glucopyranoside,4),1,2,3,4,6-五氧-没食子酰基-β-D-吡喃葡萄糖(1,2,3,4,6-penta-galloyl-β-D-glucopyranoside,5),1～5均为首次从该属植物中分离得到。Five tannin compounds were isolated from the AcOEt extraction of Ampelopsis japonica (Thunb. )Makino. By means of spectral analyses and chemical methods, they were identified to be gallic acid (1). 1,2, 6-tri-O-galloyl-β-D-glucopyranoside (2), 1,2, 3,6-tetra-O-galloyl-β-D-glucopyra-noside (3) ,1,2,4,6-tetra-O-galloyl-β-D-glucopyranoside ,(4),1,2,3,4,6-penta-O-galloyl-β-D-glu-copyranoside(5).
