A triterpenoid saponin have been isolated from n-butanol fraction of the seeds of kolowe (Chydenanthus excelsus). The structure was determined as 3-O-[β-D-glucopyranosyl(1→3)-β-D-xylopyranosyl(1→3)- β - D-glucuronopyranosyloxy]- 22α -O-(2-methylbutiroyloxyolean-12-en-15α,16α,28-tri-hydroxy. Structure elucidation was accomplished by NMR (HMBC, HMQC/HSQC, ROE, ROESY, TOCSY) methods, ESIMS, and IR spectroscopic.

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-{[β-D-galactopyranosyl(1→3)-β-D-glucopyranosyl (1→2)]-β-D-glucuronopyranosyloxy}-22-O-[2-(E)-methyl-2-butenyloyloxy]-15, 16,28-trihydroxy-(3β,15α,16α,22α)-olean-12-ene. This compound showed antifeedant activity towards Epilachna sp larvae

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-{[β-D-galactopyranosyl(1→3)-β-D-glucopyranosyl(1→2)]-β-D-glucuronopyranosyloxy}-22-O-[2-methylbutyroyloxy]-15,16,28-trihydroxy-(3β,15α,16α,22α)-olean-12-ene.

ISOLATION AND STRUCTURE DETERMINATION OF BISDEMTHYLAAPTAMINE FROM BUNAKEN MARINE PARK SPONGE Aaptos, sp. Wilson AR Rombang; Rymond J Rumampuk; Ponis Tarigan; Anthony J Herlt; Lewis N Mander

Bisdemethylaaptamine, an alkaloid naphtyridine with molecular weight 200 and formulae molecule C11H8N2O2 has been isolated from Bunaken Marine Park sponge Aaptos sp. Isolation was done by using several stages of column chromatography and high performance liquid chromatography. Molecular weight of this naphtyridine alkaloid was determined by electron ionization (EI) and electrospray ionization (ESI) mass spectroscopies and its structure assigned to be 8,9-dihydroxy-1H-benzo[d,e][1,6]naphtyridine by proton and carbon nuclear magnetic resonances (1H and 13C-NMR).

IDENTIFICATION AND SEQUENCING BY NMR SPECTROSCOPY OF THE CARBOHYDRATE MOIETY IN A SAPONIN FROM Barringtonia asiatica Rymond J Rumampuk

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 correlation NMR spectroscopy. The 1H and 13C NMR signals of the sugar residues can be determined and distinguished from one other by use of the HMQC-TOCSY technique. Anomeric configurations were unambiguously assigned from the vicinal coupling constants 3JH-1,H-2 of the anomeric protons. Inter-glycosidic linkage assignments were elucidated using HMBC.

CHEMICAL CONSTITUENTS FROM THE STEM BARK OF Alangium kurzi, Craib Sofyan M Nur; Soetijoso Soemitro; Husein Hernandi Bahti; Ponis Tarigan; Yue Mao Shen; Rymond J Rumampuk

Three new chemical constituents have been isolated from the stem bark of Alangium kurzii Craib. The structures were respectively determined to be 4-cyclohexene-1,2,3-triol 1, 3-β-stigmast-5-en-3-ol (β-sitosterol 2), and 3-O-β-D-glucopyranosyl-stigmast-5-ene (daucosterol 3). These compounds are preliminary isolated from this plant.
