Antioxidant and antimicrobial of three extracts of Caralluma deflersiana Laver

الملخص

This study focused on one traditional herb used in Yemen, Caralluma deflersiana. The antioxidant activity of the
extracts was examined using the bipyridine-ferric reducing antioxidant capacity assay, as well as the antibacterial
activity against S. aureus, P. aeruginosa, E. coli, and C. albicans microbial strains using the agar diffusion method.
The highest antioxidant activity was observed for the ethyl acetate extract. 370 µg ASA/mg ascorbic equivalent
µg ASA/mg (p< 0.05). Acetone and chloroform extracts showed decreased activity and 340 and 305 ascorbic
equivalents µg ASA/mg, respectively. The three extracts inhibited the growth of the three bacterial and one fungal
species, with MIC values ranging from 55.0 80.7 µg/ml. The selected extracts may be developed to explore new
pharmacological possibilities for their application.
