Abstract

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. Keyword: Alangium kurzii, Alangiaceae, 4-cyclohexene-1,2,3-triol, β-sitosterol, daucosterol.

Abstract

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.   Keywords: Chydenanthus excelsus, Lecythidaceae, Triterpenoid saponin
