摘要
The in vivo hepatoprotective potential of methanolic extract of Ceasalpinia bonduc (CBLM) has been explored against carbon tetrachloride (CCl4) induced acute liver injury in rats. Treatment of plant extract on CCl4 intoxicated liver significantly reduced the hepatoxicity, along with serum enzymes GPT and GOT. To explore the chemical constituents from CBLM extract, it was fractionated into non-polar to moderately polar fractions (CBLM-H, CBLM-HEt, CBLM-Et, CBLM-EtM, CBLM-M) and subjected to GC/GC-MS analysis. Altogether twenty seven (similar to 71%) phytochemicals were identified from different fractions by using Electronic Mass Spectral Library GC-MS (NIST 20). Out of which twenty one are first time reported from Ceasalpinia bonduc, fourteen from genus Caesalpinia and ten from family Fabaceae. The identified phytochemicals 2-ethyl-2-hydroxy-1,3-dimethylcyclopentanecarboxylic acid, ethyl ester (21) and 1,3,5-triazine-2,4-diamine, 6-hydroxy-N,N-dicyclohexyl (23) are first time identified as plant metabolites. To explore the antimicrobial potential four strains of Gram-positive and eight strains of Gram-negative bacteria were used along with pure cultures of five saprophytic fungus (molds) and two strains of yeast were utilized. CBLM-H and CBLMHEt were exhibited praiseworthy antimicrobial potential. CBLM-H showed complete growth inhibition of P. mirabilis and V. cholerae at the concentration of 0.1 mu g/mL while CBLM-HEt at 0.05 mu g/mL halted the growth of S. aureus.
