| 摘要 | Seven compounds were isolated from the EtOH extraction of the twig of Carapa guianensis Aubl. (Meliaceae). On the basis of spectroscopic methods, their structures were elucidated as (-)-epicatechin-3-O-(3" , 5"-di-O-methyl) gallate (1), (-)-catechin (2), sciadopitysin (3), cleomiscosin B (4), photogedunin (5), chisocheton compound F (6) and odoratone (7), respectively. Among them compound 1 was a new flavane, compounds 2-7 were firstly obtained from this plant, and compound 5 was assigned the C-13-NMR data for the first time. Compound 7 exhibited strong antifeedant activity against Pieris brassicae, and compound 2 exhibited moderate activity, while the n-BuOH portion showed weak activity. |
