New cerebroside from leaves of pineapple

目的:研究菠萝叶中的化学成分。方法:采用硅胶,Sephadex LH-20及大孔吸附树脂等色谱分离技术,用波谱学方法确定结构。结果:从菠萝叶80%乙醇提取物中分离得到1个酰胺类化合物,利用NMR,IR,MS等波谱和光谱技术,确定了它的结构为1-O-β-D-葡萄糖-N-正二十二碳酰基-正十六碳-4,10(E,E)-二烯鞘胺醇苷。结论:该化合物为一新化合物。

Objective： To study the chemical constituents of the leaves of pineapple. Method： Chromatographic methods were used to isolate compounds from the leaves of pineapple and spectral methods were used to identify the structures of the isolated compounds. Result： Compound 1 was isolated from the leaves of pineapple. It was identified as 1-O-β-D-glucopyranosyl-（2S, 3R, 4E, 11E ） -2-E （2 （R） -hydroxydocosanoyl） amido] -4, 11-hexadecanediene-1, 3-diol. Conclusion： Compound 1 was a new compound.
