Lime peel essential oil is use as an aroma and flavour enhancer. The present study deals with the pharmacognostic and preliminary phytochemical evaluation of Citrus aurantifolia (Christm) Swingle peel extract including macroscopic, microscopic characters, physiochemical evaluation and preliminary phytochemical study. Thin layer chromatography has also been performed. Microbial load of dried powder material was determined to avoid the contamination and for safety of crude drug. The present work will provide referential information for the correct identification and standardisation of the crude drug and will ensure the use of only genuine and uniform material in preparation of herbal formulation.
