目的：研究云南西双版纳景洪哥纳香（Ｇｏｎｉｏｔｈａｌａｍｕｓｃｈｅｌｉｅｎｓｉｓ）茎皮的化学成分。方法：利用各种色谱技术进行分离纯化，根据理化性质和光谱数据等进行结构鉴定。结果：从景洪哥纳香茎皮的乙醇提取物中分离得到１０种化合物，其中５个化合物结构分别鉴定为：５，７二羟基双氢黄酮Ⅰ、５，６２Ｈ６苯乙烯吡喃２酮Ⅱ、（５Ｒ，６Ｓ，７Ｒ，８Ｒ）７羟基８苯基四氢呋喃并［３，２ｂ］２Ｈ吡喃２酮Ⅲ、（６Ｒ，７Ｒ，８Ｒ）６（７，８二羟基苯乙基）５，６２Ｈ５羟基２吡喃酮Ⅳ、（６Ｒ，７Ｒ，８Ｒ）６（７，８二羟基苯乙基）５，６２Ｈ吡喃２酮Ⅴ。结论：５种化合物均首次从该植物中获得。 Objective: To study the chemical constituents of the bark of Gonoothalamuscheliensis in Xishuangbanna, Yunnan. Methods: Separation and purification were performed by various chromatographic techniques. Structure identification was performed based on physicochemical properties and spectral data. RESULTS: Ten compounds were isolated from the ethanol extract of the scented bark of Jinghong Gona, 5 of which were identified as: 5,7dihydroxyflavone I,5,62H6benzene Ethylene pyran-2-ketone II, (5R,6S,7R,8R)-7-Hydroxy-8Phenyltetrahydrofuran and [3,2-b]-2H-pyran-2-ketone III, (6R, 7R,8R)-6(7,8-dihydroxyphenethyl)5,6-2H-5-hydroxy-2-pyrone-4-(6R,7R,8R)-6(7,8 Dihydroxyphenylethyl) 5,6 2H-pyran-2-ketone V. Conclusion: Five compounds were obtained from this plant for the first time.
