Constituents of Carapa guianensis Aubl. (Meliaceae).
Nine compounds were isolated from the EtOH extraction of the twig of Carapa guianensis Aubl. On the basis of spectroscopic methods, their structures were elucidated as 1,3-di-benzene carbon amine-2-octadecylic acid-glyceride (1), hexacosanoic acid-2,3-dihydroxy-glyceride (2), ursolic acid (3), naringenin (4), scopoletin (5), 3,4-dihydroxymethylbenzoate (6), 2,6-dihydroxymethylbenzoate (7), tetratriacontanoic acid (8), triacontanoic acid (9) respectively. Among them 1 was new, 2 was firstly isolated from nature, and 3-9 were obtained from this plant for the first time.
