Abstract
One new havanensin-type limonoid (1) named trisinlin A with two known compounds (4E,8E)-2-[2′-hydroxyhexadecanoyl amino]-4,8-octadecadiene-1,3-diol (2), 9-octadecenoic acid-2′,3′-dihydroxypropyl ester (3) were isolated from the roots of Trichilia sinensis. The structure of the new compound was unambiguously determined through comprehensive spectroscopic analyses including 1D and 2D NMR, and mass spectrometry, as well as by comparison with the literature. Trisinlin A showed significant insecticidal activity against newly hatched larvae of Spodoptera litura.
