Evaluation of the antimicrobial activity of Gooseberry and Wild Apple fruit juices of the northeast region of India

Abstract

A large number of wild fruits belonging to the north eastern region of India are considered to be nutritionally abundant and traditionally used for the treatment of various ailments. In the present study, juices of gooseberry and wild apple have been evaluated for their antimicrobial activity in its consumable form as a potential source of natural anti-infective agent. The fruit juices were screened for their antibacterial and antifungal activities qualitatively, using the agar well diffusion method followed by quantitative assessment by determining the minimum inhibitory concentration and minimum bactericidal concentration. The study revealed that both the fruit juices exhibited broad spectrum antibacterial activity. Considerable activity against drug-resistant pathogens such as methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and extended spectrum β-lactamases producing Gram-negative bacteria was observed. Thus, this study highlights the antibacterial efficacy of wild apple and gooseberry fruit juices and augments the beneficiary properties of highly nutritional fruit juices that are specific to Indian region.

Emblica officinalis (Amla) with a Particular Focus on Its Antimicrobial Potentials: A Review

“…The result suggests that the fruit extract produces maximum inhibition against Gram-positive rather than Gram-negative bacteria, again confirming superior antibacterial effectiveness of EO for Gram-positive bacteria. Screening the juices of gooseberry and wild apple for antibacterial and antifungal potentials revealed significant levels of antibacterial action for drug-resistant microbes (methicillin-resistant S. aureus, vancomycinresistant Enterococci, β-lactamases producing Gram-negative bacteria) 76 . The antimicrobial evaluation of Indian gooseberry and galangal (Alpinia galanga) extracts for S. aureus revealed MIC values of 13.97 and 0.78 mg/ml, and minimum biocidal concentration (MBC) of 13.97 and 2.34 mg/ml, respectively 77 .…”
