To study the chemical constituents of the root of Inula cappa.
The compounds were isolated and purified by recrystallization and chromatography with silica gel column and Sephadex LH-20 column. Their structures were identified by physico-chemical properties and spectral analysis.
Seven compounds were isolated as scopolin (I), octacosanoic acid (II), tritriacontane (III), (2S,3S,4R,8E)-2-[(2'R)-2'-hydroxydocosanosylamino]-octadecane-1,3,4-triol(IV),(2S,3S,4R,8E)-2-[(2'R)-2'-hydroxytricosanosylamino]-octadecane-1,3,4-triol(V), (2S,3S,4R,8E)-2-[(2'R)-2'-hydroxytetracosanosylamino]-octadecane-1,3,4-triol(VI), (2S,3S,4R,8E)-2-[(2'R)-2'-hydroxypentacosanosylamino]-octadecane-1,3,4-triol(VIII), (2S,3S,4R,8E)-2-[(2'R)-2'-hydroxyhexacosanosylamino]-octadecane-1,3,4-triol(VIII).
All compounds were isolated from Inula cappa for the first time.
研究羊耳菊根的化学成分。
通过重结晶以及硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱对化合物进行分离和纯化。通过理化性质和光谱分析鉴定其结构。
分离得到7种化合物,分别为东莨菪苷(I)、二十八烷酸(II)、三十三烷(III)、(2S,3S,4R,8E)-2-[(2'R)-2'-羟基二十二烷氨基]-十八烷-1,3,4-三醇(IV)、(2S,3S,4R,8E)-2-[(2'R)-2'-羟基二十三烷氨基]-十八烷-1,3,4-三醇(V)、(2S,3S,4R,8E)-2-[(2'R)-2'-羟基二十四烷氨基]-十八烷-1,3,4-三醇(VI)、(2S,3S,4R,8E)-2-[(2'R)-2'-羟基二十五烷氨基]-十八烷-1,3,4-三醇(VII)、(2S,SS,4R,8E)-2-[(2'R)-2'-羟基二十六烷氨基]-十八烷-1,3,4-三醇(VIII)。
所有化合物均为首次从羊耳菊中分离得到。
