Salvadora persica, Miswak, Antimicrobial, Antioxidant


Herbal medicine is an effective treatment for many diseases that are intractable to traditional
medicine. Salvadora persica L. is an extensively utilized plant by many Arab populations
worldwide due to its varied medical benefits. The study looks at plant roots' antimicrobial and
free radical scavenging properties of flavonoid, glycoside, and alkaloid extracts. The activity of
the extracts was evaluated for Escherichia coli, Staphylococcus aureus, Pseudomonas
aeruginosa, and Candida albicans. Based on the findings, the three extracts recorded no activity
towards the selected microorganisms except the flavonoid extract which showed an efficacy
close to that of amoxicillin against Staphylococcus aureus and Escherichia coli growth with
inhibition zones 14mm and 15mm respectively. Inhibiting lipid peroxidation was more
successfully accomplished by flavonoid extract which recorded 50% compared to standard
compound BHT (60%), the glycoside and alkaloid extracts exhibited noticeable activity as
antioxidant with 27% and 18.4 % inhibition.
