【摘要】 从连香树（CercidiphyllumjaponicumSieb.etZucc.）树皮中分离到8个化合物。其中7个为黄酮醇，l个为酚酸类成分。经理化测定和波谱解析，分别鉴定为：5，7-二羟基-3，8，4’-三甲氧基黄酮（Ⅰ）、3，5，7-三羟基-8，4’-二甲氧基黄酮（Ⅱ）、5，7，4’-三羟基-3，8-二甲氧基黄酮（Ⅲ）、3，5，7，4’-四羟基-8-甲氧基黄酮（Ⅳ）、3，5，7，4’-四羟基黄酮（Ⅴ）、5，7-二羟基-8，4’－二甲氧基黄酮-3-O-葡萄糖甙（Ⅶ）、5，7，4’-三羟基-8-甲氧基黄酮-3－O-葡萄糖甙（Ⅷ）和没食子酸乙酯（Ⅵ）。其中化合物Ⅶ为未见报道的新化合物。除化合物Ⅴ外，其余化合物均为首次从该属植物中分得。更多还原

【Abstract】 Eight compounds were isolated from the bark of Cercidiphyllum japonicum Sieb. et Zucc. Theirstructures were identified with spectral and chemical methods as 5, 7-dihydroxy-3, 8, 4’-trimethoxyflavone(Ⅰ), 3, 5, 7-trihydroxy-8, 4’-dimethoxyflavone (Ⅱ), 5, 7, 4’-trihydroxy -3, 8-dimethoxyflavone (Ⅲ), 3, 5,7, 4’- tetrahydroxy- 8 - methoxyflavone (Ⅳ), 3, 5, 7, 4’ - tetrdhydroxyflavone (Ⅴ), 5, 7 - d ihydroxy- 8, 4’ dimethoxy- 3 - O- glucoside (Ⅶ), 5, 7, 4’ - trihydroxy-8- methoxyflavone- 3 - O-glucoside (Ⅷ). One phenol acidcompound was identified as ethyl gallate (Ⅵ). AInong them, compound Ⅶ is a new compound that has neverbeen reported. Except compound Ⅴ, all the other compounds were isolated from this genus for the first time.更多还原
