• Six compounds, Z- and E-fadyenolide (3, 4), 1-allyl-2, 3-(methylenedioxy)-4, 5-dimethoxy-benzene (5), 4-methoxy-3, 5-bis (3'-methyl-2'-butenyl)-benzoic acid (6), 2, 6-dihydroxy-4-methoxy-dihydrochalcone (7), and 5-hydroxy-7-methoxyflavanone (8) were isolated from three species of Jamaican Piper, Piper fadyenii, C.D.C., Piper aduncum L. and Piper hispidum Sw. Three amides (9〜11) of 3, 5-dimethoxy-4-oxo-5-phenylpent-2-enoic acid using piperidine, pyrrolidine and morpholine, respectively, were synthesized from compounds 3 and 4, and tested for insecticidal activity against the tick Boophilus microplus (Canestrini) and the flour feetle, Tribolium confusum Duval. In our experiment, compounds 9〜11 inhibited ovogenesis of B. microplus and were toxic to T. confusum. Compounds 3〜8 were found to have no activity.
