荚果蕨贯众化学成分研究

Chemical constituents of the rhizome of Matteuccia struthiopteris

摘要: 目的对荚果蕨贯众的化学成分进行研究。方法用色谱法分离化合物，根据理化性质和光谱数据鉴定结构。结果分离鉴定了4个化合物：1-O-β-D-葡糖基-(2S,3R,4E，8Z)-2-N-(2′-羟基二十二碳酰)-二十碳鞘氨醇-4,8-二烯(1)，1-O-β-D-半乳糖-(6→1)-α-D-半乳糖-2,3-O-十六烷酸甘油二酯(2)，丁二酸(3)，D-甘露糖醇(4)。结论化合物1和2为新化合物，3和4为首次从该植物中分离得到。

Abstract: AimTo study the chemical constituents of the rhizome of Matteuccia struthiopteris (L.) Todaro. MethodsThe constituents were separated and purified by column chromatography with normal phase silica gel and Sephadex LH-20. Their structures were identified on the basis of physical and spectral data(MS, NMR, HMBC and HMQC). ResultsFour compounds were isolated and identified as 1-O-β-D-glucopyranosyl-(2S,3R,4E,8Z)-2-N-(2′-hydroxydocosanoyl) eicosasphinga-4，8-dienine (1), 1-O-β-D-galactosyl-(6→1)-α-D-galactosyl-2,3-O-dihexadecanoyl-glycerol (2), succinic acid (3), D-mannitol (4). ConclusionCompounds 1 and 2 are new compounds. Compounds 3 and 4 were isolated from this plant for the first time.
