Salah satu tanaman yang berpotensi sebagai pestisida nabati adalah Bitung (Baringtonia asiatica) yang teruji mengandung terpenoid dan saponin. Penelitian ini bertujuan untuk  mengetahui toksisitas ekstrak kasar (B. asiatica) terhadap mencit putih (Mu... see more

An examination of insect resistance was determined by several steps, i.e. standard sensitivity, resistance diagnosis, and determination of resistance level. Each phase was tested with feeding and residue contact methods at glass tube. Resistance ratio (RR... see more

An antifeedant triterpenoid saponin has been isolated from the seed of Barringtonia asiatica and its structure elucidated mainly by two dimensional NMR spectroscopy is identified as 3-O-{[ß-D-galactopyranosyl(1?3)-ß-D-glucopyranosyl (1?2)]-ß-D-glucuronopy... see more

A trisaccharide chain in a saponin from the seeds of Barringtonia asiatica has been identified and sequenced as {[b-D-galactopyranosyl(1®3)- b-D-glucopyranosyl(1®2)]-b-D-glucuronopyranosyloxy} using a combination of homonuclear and heteronuclear correlati... see more

A triterpene ester saponin has been isolated from the seed of Barringtonia asiatica and its structure has been established by extensive application of high-resolution FABMS and two dimensional NMR techniques to be 3-O-{[ß-D-galactopyranosyl(1?3)-ß-D-gluco... see more
