- Abstract: OBJECTIVE: To study the phenolic constituents from Caesalpinia decapetala (Roth) Alston. METHODS: The ethanol crude extract of C. decapetala was fractionalized by using petroleum ether and chloroform. The chloroform part was isolated by a series of chromatography methods, and the structures of purified compounds were elucidated by their physicochemical properties and spectroscopic data. RESULTS: Eleven phenolic compounds were isolated and identified as methyl 2,3,5-trihydroxybenzoate (1), protocatechuic acid methyl ester (2), N-trans-feruloyl tyramine (3), trichostachine (4), cinnamylpiperidine (5), gallic acid (6), methyl 3,4,5-trihydroxybenzoate (7), ethyl 3,4,5-trihydroxybenzoate (8), resveratrol(9), 3,4,3',5'-tetrahydroxydistyrene (10), and protosappanin A (11). CONCLUSION: Compounds 1-5 are isolated from this plant for the first time.
