目的研究红树伴生植物山石榴Catunaregamspinosa的化学成分。方法利用柱色谱进行分离和纯化,通过光谱分析鉴定结构。结果分离到9个化合物,鉴定为香草醛(vanillin,Ⅰ)、原儿茶醛(3,4-dihydroxybenzal-dehyde,Ⅱ)、对羟基苯甲酸(p-salicylic acid,Ⅲ)、3,4-二羟基苯甲酸甲酯(methyl3,4-dihydroxybenzoate,Ⅳ)、3,4-二羟基苯甲酸乙酯(ethyl3,4-dihydroxybenzoate,Ⅴ)、4,5-二羟基-1,2-苯二甲酸甲酯(4,5-bis(hydroxy)phthalic aciddi methyl ester,Ⅵ)、异橙黄胡椒酰胺乙酸脂(diaaurantiamide acetate,Ⅶ)、2,6-二甲氧基苯醌(2,6-di methoxy-1,4-benzoquinone,Ⅷ)和单棕榈酸甘油酯(glycerol monopal mitate,Ⅸ)。结论9个化合物均为首次从该植物中分离得到,化合物Ⅶ是首次从陆生植物里分离得到。
Objective To study the chemical constituents of Catunaregamspinosa, a mangrove plant. The method was separated and purified by column chromatography and identified by spectral analysis. Results Nine compounds were isolated and identified as vanillin (Ⅰ), 3,4-dihydroxybenzal-dehyde (Ⅱ), p-salicylic acid (Ⅲ) Methyl 3,4-dihydroxybenzoate (Ⅳ), ethyl 3,4-dihydroxybenzoate (Ⅴ), 4,5-dihydroxy-1,2-benzenedioic acid (4,5-bis (hydroxy) phthalic aciddi methyl ester, Ⅵ), diaaurantiamide acetate (Ⅶ), 2,6-di methoxy- 1,4-benzoquinone, Ⅷ) and glycerol monopalmitate (Ⅸ). Conclusion All nine compounds were isolated from this plant for the first time. Compound Ⅶ was isolated from terrestrial plants for the first time.
