Adesmia aegiceras:: antimicrobial activity and chemical study

The antimicrobial activity of the ethanolic extract of Adesmia aegiceras was studied by the agar-well diffusion method. Antibacterial activity against Micrococcus luteus and eight pathogenic bacterial strains as well as antifungal activity against Candida albicans, was detected. Bacterial and fungal strains exhibited similar concentration-response curves (EC50 and R-max values) and similar MIC. The MBC/MIC was about 8. These data would indicate the potential usefulness of the A. aegiceras extract as a microbiostatic, antiseptic or disinfectant agent. Furthermore, chemical study of the bioactive alcoholic extract was performed, which revealed quercetin, isorhamnetin-3-rutinoside, isovitexin, pinitol and chlorogenic acid as its main components.
