In the last few decades, field of herbal medicine is gaining importance in developing and developed countries due to its natural origin, lesser side effects and many other advantages. The scientific evidence has brought about the possibility of utilization of herbal plant in the treatment of fungal and bacterial infections and the development of anti-bacterial and anti-fungal products.
Objective: To evaluate the in vitro antimicrobial activity of Emblica officinalis bark extracts against dental caries pathogens namely Streptococcus mutans, Streptococcus salivarius, Streptococcus mitis and Lactobacillus species, Prevotella intermedia which is a periodontal pathogen and a fungal organism Candida albicans.
Methods: The barks of E. officinalis were collected and different solvents were used for the preparation of the extract namely petroleum ether, dichloro methane, ethyl acetate, methanol and aqueous solvent. The antibacterial potential was evaluated using the agar well diffusion assay.
Result:The largest zone of inhibition was obtained with the methanol extract of Emblica officinalis against Lactobacillus species (16mm) followed by Prevotella intermedia(14mm) and Streptococcus mitis(12mm). Antifungal activity was exhibited by methanol and ethyl acetate extract with zone of inhibition of 10mm and 8mm respectively.
Conclusion: Emblica officinalis enjoys good antimicrobial activity and can be used as a potential source of antimicrobial agents against pathogens effecting oral health.
