Abstract


Aim: The present study aimed to evaluate the in vitro antimicrobial activity of hydroalcoholic and aqueous extracts from leaves of P. guajava on two bacterial samples to determine the range of minimum inhibitory concentration of the extracts. Material and Methods: The antimicrobial activity of extracts of different polarities was compared using the agar dilution method. Differences in susceptibility to the active ingredient could be observed. Result: The results showed that the hydroalcoholic extract was active against Escherichia coli (1024µ gƒml) and Bacillus cereus (900µgƒml). The aqueous extract showed no antimicrobial activity. Conclusion: Despite demonstrating antimicrobial efficiency, the P. guajava extract may be insufficient or may require a higher concentration to be fully effective. KEYWORDS: Ethnomedicinal, Antibacterial, Psidium guajava extracts
