• 論文の詳細を見る

• The petroleum ether extract of dried ground whole fruits of Piper nigrum L. afforded 20 compounds (1-20) including two new insecticidal amides named as pipnoohine (1), and pipyahyine (2), seven reported for the first time from this plant (12, 13, 15-17, 19, 20), and eleven known compounds (3-11, 14, 18). The structure of 1 has been elucidated as (2E, 4E, 12Z)-N-(4-methylpentyl)octadeca-2, 4, 12-trienamide and that of 2 as (2E, 4E, 11E)-12-(benzo[1, 3]dioxol-5-yl)-N-(3-methylbutyl)dodeca-2, 4, 11-trien-amide through extensive ID-, 2D-NMR spectral studies and chemical reactions. The known compounds have been identified through comparison of their spectral data with those reported in literature. 1 and 2 exhibited toxicity at 35.0 and 30.0 ppm respectively against fourth instar larvae of Aedes aegypti L. by WHO method.
