Abstract:AIM: To study the chemical constituents from the stem of Caesalpinia decapetala. METHODS: The compounds were isolated by column chromatography using silica gel and Sephadex LH-20, and their structures were identified on the basis of spectral analysis. RESULTS: Seven compounds were obtained from the ethanol extract and their structures were elucidated as 6′-hydroxy-3, 4-( 1″-hydroxy-epoxy propane) -2′, 3 ′-(1″′β-hydroxy-2″′-carbonyl-cyclobutane) -1, 1 ′-diphenyl (1), octacosyl 3, 5-dihydroxycinnamate (2), 2′, 4, 4′- trihydroxychalocone (3) , bonducellin (4), 7, 3′, 5′-trihydroxyflavanone (5), daucosterin (6), and β- sitosterol (7). CONCLUSION: Compounds 1 and 2 are new compounds and 3-6 were obtained from this plant for the first time.
