Litchi chinensis

Phytochemical techniques played a significant role in searching raw materials and resources for pharmaceutical industry. Preliminary Phytochemical tests are helpful in finding and locating chemical constituents which are source of pharmacologically active principles.  were carried out by employing standard methods for conducting Qualitative phytochemical analysis for studying the presence of active compounds like alkaloids, glycosides, phenols, saponins, tannins flavonoids, volatile oils, reducing sugars and steroids. Aqueous pericarp extract of Litchi chinensis showed presence of phenolic compounds, except flavonoids, volatile oils alkaloids, glycosides, saponins, tannins, reducing sugars and steroids. The antimicrobial activity of aqueous pericarp extract of Litchi chinensis was studied by agar well diffusion method in vitro.   The effect of antimicrobial potential was examined Salmonella typhi, Vibrio cholerae, Shigella dysenteriae, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus and Candida albicans. The aqueous extract of the fruit pericarp has showed consistently significant inhibitory activity on different bacterial species tested and found the significance of antimicrobial activity of Litchi chinensis.
