ABSTRACT
Aims:
Camellia sinensis ( green t ea) is known for its therapeutic properties (anti - inflammatory, anti - oxidative and anti - ageing). The aim of this study was to determine the in vitro inhibitory activity of gree n tea extract on some odorous skin commensal bacteria. Methodology andresults:
Tea leaves were collected from MARDI Agro Technology Park, Cameron Highlands. A standardised protocol was used to obtain green tea extract. Aqueous green tea extracts were tes ted for antibacterial activity by well diffusion method. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) assays were performed by broth microdilution assays using green tea extract concen trations from 16 to 0.0313 mg/ mL . Green tea extract showed antibacterial activity against skin microbiota. The high antimicrobial effect was achieved against Micrococcus luteus with MIC and MBC of 0.125 and 0.25 mg/μL respectively, followed by Staphylococcus epidermidis with MIC and MBC o f 0.25 and 0.25 mg/μL respectively, Bacillus subtilis with MIC and MBC of 0.5 and 0.5 mg/μL respectively and lastly, Corynebacterium xerosis with MIC and MBC of 0.5 and 1.0 mg/μL respectively. Conclusion, significance and impact of study The results obta ined from the study confirm the in vitro anti - microbial activity of green tea extracts against skin microbiota. The antibacterial effects of green tea against skin bacteria with its anti - oxidant and anti - aging properties will help in keeping skin healthy, fresh and reducing unpleasant odo rs .
