Abstract
In the present day scenario perishable fruit peels are considered as a new era of pharmaceutical products as they are rich in phytochemicals and act as antioxidant agents. Lemon peel which is a good source of several bioactive compounds is usually discarded or thrown away after extracting the juice from it. The present study was carried out to determine the presence of various phytochemicals such as terpenoids, alkaloids, glycosides, phytosterols, diterpenes, phenols, tannins, flavonoids and saponins in lemon peel. Secondary derived plant metabolites such as phenols, flavonoids, diterpenes, phytosterols and cardiac glycosides were present in both methanol and acetone extract while saponins was present only in methanol extract. The presence of various phytoconstituents was further confirmed using thin layer chromatography technique. Hence the result of the present study indicates the use of lemon peel in various value added products thereby benefitting several industries.
