摘  要:目的:研究广南天料木Homalium paniculiflorum茎的化学成分。方法:应用硅胶柱色谱、Sephadex LH-20柱色谱、反相柱色谱及重结晶等分离纯化,根据理化性质和光谱数据鉴定化合物结构。结果:从广南天料木茎的乙酸乙酯部位分离鉴定了13个化合物,它们的结构分别鉴定为:4-羟基-3-甲氧基苯甲醛(1),2,4-二羟基苯甲醛(2),3-苯基异香豆素(3),4-羟基苯丙烯醛(4),4-羟基-3,5-二甲氧基苯甲酸(5),kaempferol(6),arimadendrin(7),4-羟基-3,5-二甲氧基苯丙烯醛(8),2-羟基-苯甲酸(9),28-O-acetylbetulin(10),胆固醇(11),苯甲酸(12),木栓酮(13)。结论:化合物3,5,7-11,13为首次从该科植物中发现,所有化合物均为首次从该属植物中分离得到。Objective: To study the chemical constituents of the stems of Homalium paniculiflorum. Method: The compounds were isolated by many kinds of chromatography methods and identified on the basis of physico-chemical characters and spectroscopic analysis. Result: Thirteen compounds were obtained from the EtoAc extracts of the stems of H. paniculiflorum, and their structures were identified as 4-hydroxy-3-methoxybenzaldehyde (1), 2, 4-dihydroxybenzaldehyde (2), 3- (phenyl) isocoumarin (3), 4-hydroxy styrene aldehyde (4), 4- hydroxy-3, 5-dimethoxy-benzoic acid (5) , kaempferol (6), arimadendrin (7), 4-hydroxy-3, 5-dimethoxy styrene aldehyde (8), 2-hydroxy-benzoicacid (9), 28-O-acetylbetulin ( 10), cholesterol ( 11 ), benzoic acid (12) and 5a-cholestan-3-one (13). Conclusion: Compounds 3, 5, 7-11, 13 were isolated from the family Flacourtiaceae for the first time. All compounds are firstly isolated from the genus H. paniculiflorum.
