Abstract

Objective: To study the chemical constituents of the root of Inula cappa.

Method: 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.

Results: 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).

Conclusion: All compounds were isolated from Inula cappa for the first time.
