ABSTRACT

Lemon (Citrus) are acidic fruits of family Rutaceae. Lemon is called the tree of life because of its many medicinal properties. Almost all parts of the fruit can be used against different diseases due to its wide range of medicinal property. Other than medicinal property they also have antioxidant, antimicrobial, insect repellent, nutritional and many other properties. Different bio-compounds of lemon can replace the function of synthetic drugs which are available in market. In the present study, the antimicrobial extent of crude juice, different extracts of leaf (matured and young), peel in methanol and standards streptomycin and tetracycline (1mg/mL) was determined against E. coli by agar diffusion method. The highest and minimum inhibition zone was found in crude juice (more than the standard) and matured leaf respectively. MIC for the crude juice was recorded as 0.01μL/mL (v/v) and for streptomycin and tetracycline was recorded as 0.1μg/mL and 0.01μg/mL respectively. The study clearly points out the antimicrobial potential emphasizing the importance of incorporating lemon as a regular component in diet.

Keywords: MIC, inhibition zone, streptomycin, tetracycline, therapeutic treatments.
