ISOLASI DAN ELUSIDASI STRUKTUR TRITERPENOID KULIT BATANG SURIAN Toona sinensis DAN UJI TERHADAP HAMA Crosidolomia pavonana
ABSTRACT: Tryterpenoid
compound (3-hydroxyeupha-7-ene) were isolated from hexane fraction the steam
bark of Toona sinensis (Meliaceae). The structures of these compounds were
established base on spectroscopic evidence, including UV, IR, 3C-NMR, 1H-NMR,
HMBC, HMQC and COSY spectra and literature survey this is new compound in
family Meliaceae. Insect activity of the hexane fraction (1.0%) and against
Crosidolomia pavonana were tested. The activity of hexane were mortality
(37.5%), antifeeding (75.5%). The activity of the 3-hydroxyeupha-7-ene showed
mortality (52.0%), Lc50; 0.39847 and Lt50; 5.53931.
