New furanoid diterpenes from Caesalpinia pulcherrima.
Four new cassane-type furanoditerpenoids (1-4) were isolated from the air-dried leaves of Caesalpinia pulcherrima. Their structures were elucidated by spectral data interpretation. The exocyclic methylene compound 1 readily isomerized and oxidized to the benzofuran 4. Benzyl 2,6-dimethoxybenzoate (5) was also identified in this study. Antimicrobial tests on 1-5 indicated that they were active a...
متن کاملStructures and binding specificity of galactose- and mannose-binding lectins from champedak: differences from jackfruit lectins.
Galactose-binding and mannose-binding lectins from the champedak fruit, which is native to South-east Asia, exhibit useful potential clinical applications. The specificity of the two lectins for their respective ligands allows the detection of potential cancer biomarkers and monitoring of the glycosylated state of proteins in human serum and/or urine. To fully understand and expand the use of t...
متن کاملAntioxidant and cytotoxic activities of Caesalpinia pulcherrima wood.
Antioxidant and cytotoxic activities of the methanolic and aqueous extracts of Caesalpinia pulcherrima wood were studied in in vitro models. Both extracts exhibited strong antioxidant activity, as evidenced by the low IC50 values in both 1,1-diphenyl-2-picryl hydrazyl (DPPH), nitric oxide and superoxide scavenging methods; the values were found to be less or comparable to those of gallic acid, ...
متن کاملAntimicrobial, Antioxidant and Cytotoxic Potential of Caesalpinia pulcherrima Flower
Most of the world’s populations residing in developing countries depend on alternative medicine and use of plant ingredients. Caesalpinia pulcherrima (Fabaceae) is used in folk medicine for the treatment of various diseases including asthma, bronchitis, cholera, diarrhea, dysentery and malarial infection. The present study was undertaken to determine antimicrobial, antioxidant and cytotoxic act...
متن کاملEvaluation of Antioxidant and Free Radical Scavenging Capacities of Polyphenolics from Pods of Caesalpinia pulcherrima
Thirteen polyphenolics were isolated from fresh pods of Caesalpinia pulcherrima using various methods of column chromatography. The structures of these polyphenolics were elucidated as gallic acid (1), methyl gallate (2), 6-O-galloyl-d-glucoside (3), methyl 6-O-galloyl-β-d-glucoside (4), methyl 3,6-di-O-galloyl-α-d-glucopyranoside (5), gentisic acid 5-O-α-d-(6'-O-galloyl)glucopyranoside (6), gu...
