Chinese Journal of Experimental Traditional Medical Formulae, 2014 , 20 (20) :110-113. | Chemical Constituents of Anti-in Flammatory Fraction of Caesalpinia decapetala[Reference: WebLink] | To study the chemical constituents of the anti-inflammatory fraction of Caesalpinia decapetala. METHODS AND RESULTS: The compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography and their structures were determined by chemical evidence and pectral analysis. Nine compounds were obtained from C. decapetala and they were identified as( ±) protosappanin B( 1),scopoletin-7-O-β-D-glucopyranoside( 2),4-hydroxy-3-methoxypheny-1-O-β-D-glucopyranoside( 3),( 1' R,3' S,5' R,8' S,2Z,4E)-dihydrophaseic acid-3'-O-β-D-glucopyranoside( 4),( 1'R,3'S,5'R,8'S,2E,4E)-dihydrophaseic acid-3'-O-β-D-glucopyranoside( 5), liquiritigenin( 6), isoscopoletin( 7),
7-Hydroxy-3-(4-hydroxybenzylidene)chroman-4-one
( 8),3-deoxysappanchalcone( 9). CONCLUSIONS: Compounds 2-5,7 were isolatedfrom thegenus C. for the firs time,and compounds 6,8 were obtained from the C. decapetala for the first time. |
