摘要
目的:对马齿苋(Portulaca oleracea L.)地上部分的化学成分进行研究。方法:采用多种色谱手段进行分离,通过波谱分析确定化合物结构。结果:从马齿苋中分得1个化合物为(2S,3S,4R)-2-[(2′R,4E)-2′-羟基-二十六碳烯酰胺]-3,4-二羟基-十六碳-1-O-β-D-葡萄糖苷,命名为马齿苋脑苷A。结论:该化合物为未见文献报道的新化合物,也是马齿苋中首次分离获得此类化合物。
AIM： To study the chemical constituents of the aerial part of Portulaca oleracea L.. METHODS： Several chromatographic methods were applied to isolate purify compounds and their structures were elucidated by spectroscopic methods. RESULTS： A compound named as portulacerebroside A was isolated and their structures were identified as （2S,3S,4R）-2-[（2′R,4E）-2′-hydroxy-hexacosenoylamino]-3,4-dihydroxy-hexadecane-1-O-β-D-glucopyranoside. CONCLUSION： The compound was new and such kind of compounds were never obtained in Portulaca oleracea L..
