ABSTRACT
    The present study highlights the extraction of essential oils from C. citratus and O. americanum using Microwave 
    Hydrodiffusion and Gravity method (MHG) and Hydrodistillation Method (HD), the qualitative and quantitative screening along 
    with determination of antibacterial potential. For the study, extraction of essential oils was performed using Microwave 
    Hydrodiffusion and Gravity method and Hydrodistillation Method. Comparative study was performed to check the total flavonoid 
    content (TFC), total phenolic content (TPC), biochemical test, thin layer chromatography (TLC) and determination of 
    antibacterial activity of the essential oils. The results of the study depicted that the MHG method for extraction of 
    essential oils was much better compared to extraction by HD method as supported by the biochemical tests, TFC, TPC and TLC 
    results. However, the essential oils did not show antibacterial activity. More study related to the antimicrobial activity 
    needs to be performed. Essential oils form an integral part of the pharmaceutical and healthcare industry hence, detailed 
    study regarding the isolation and application of essential oils is required. The present study suggests the use of MHG method 
    for extraction of essential oils.
Key words :   Antibacterial activity, Cymbopogon citratus, Essential oils, Ocimum americanum, Phytochemicals.
