ABSTRACT
The ethyl acetate soluble fraction of the aqueous alcoholic extract of Chorisia speciosa St. Hil. flowers yielded three flavonoids; quercetin, kaempferol-3-0-beta-D-[6"-P-coumaroyl]-glucoside [tribuloside] and apigenin-7-0-neohesperidoside [rhoifolin]. Their chemical structures were established using UV, MS,1H-,13C-and 2D-NMR spectral data as well as by direct comparison with authentic reference samples. The mucilage content [1.12%] was studied both qualitatively and quantitatively. The antibacterial study of the different extracts revealed significant activities. Tribuloside exhibited substantial antibacterial effect with MIC 1.96 mug/ml against Bacillus subtilis. Moreover, detailed macro- and micromorphological characters of the flower parts have been studied in order to find out the diagnostic features which can help in the identification of the plant flower in both entire and powdered forms
