Abstract

Two new limonoids, trichilins F and G, have been isolated from the root bark of Trichilia roka and identified as antifeedant against some pest insects. Their structures were determined from spectral data and chemical means, in which the treatment of trichilin A with zinc borohydride induced an acyl migration to yield trichilin F.
