5,5'-二羟基-2',4'-二甲氧基-7-[(6-O-β-d-呋喃糖基-β-d-吡喃葡萄糖基)-氧基]异黄酮 (1) 与四种已知化合物 5,7-二羟基-2',4',5'-三甲氧基异黄酮 (3) 一起作为牛痘黄檀根皮乙醇提取物的主要成分被分离出来， 5,7-二羟基-2',4'-二甲氧基异黄酮(4)、5-羟基-2',4',7-三甲氧基异黄酮(5)和7-羟基-2',4',5'-三甲氧基异黄酮(6)。通过对 1D 和 2D NMR 以及 MS 光谱的广泛分析，实现了化合物的鉴定。
5,5′-Dihydroxy-2′,4′-dimethoxy-7-[(6-O-β-d-apiofuranosyl-β-d-glucopyranosyl)-oxy]isoflavone (1) was isolated as the major constituent of Dalbergia vacciniifolia root bark ethanol extract together with the four known compounds 5,7-dihydroxy-2′,4′,5′-trimethoxyisoflavone (3), 5,7-dihydroxy-2′,4′-dimethoxy-isoflavone (4), 5-hydroxy-2′,4′,7-trimethoxyisoflavone (5) and 7-hydroxy-2′,4′,5′-trimethoxyisoflavone (6). Identification of compounds was achieved through extensive analysis of 1D and 2D NMR and MS spectroscopy.
