Objective: The aim of the present study was to evaluate the antioxidant activity and total phenol and flavonoid content of different parts (peel, pulp and aerial parts) of Lagenaria siceraria. Method: Successive extraction was done by cold percolation method using solvents of different polarity viz. petroleum ether, toluene, ethyl acetate, acetone, water. Total phenol content was determined by Folin-Ciocalteu\’s reagent method and flavonoid was determined by aluminium chloride colorimetric method. The antioxidant assays evaluated were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, 2, 2\’-Azino-bis-(3-ethyl) benzothiazoline-6-sulfonic acid (ABTS) radical cation scavenging activity and Ferric reducing antioxidant power. Results: L. siceraria peel possessed maximum phenol and flavonoid content in acetone and toluene extracts respectively. FRAP was maximum in acetone extract of peel. The peel extract demonstrated stronger DPPH activity with IC50 value of 111 \μg/ml followed by pulp extract. The same extract was effective in scavenging ABTS radical with an IC50 value of 39 \μg/ml while other parts were ineffective. Conclusion: This work demonstrated good antioxidant activity of L. siceraria vegetable cultivated in India and recommends that the peel of this vegetable may be of interest from a functional point of view as a major source of natural antioxidant.

Background: Lagenaria siceraria (LS) fruits belonging to Cucurbitaceae family is widely used in Indian traditional medicine for its various medicinal values. As per best of our knowledge there were no pharmacognostical reports, specifically to determine anatomical and other physicochemical standards required for its standardization. Material and Methods: In this study various standardization parameters like macroscopic and microscopic studies, physico-chemical constants, extractive values and preliminary phytochemical screening were studied and reported. Results: Different standardization parameters were reported, which would be of immense use to identify and establish the authenticity of the plant. Conclusion: Preliminary pharmacognostic evaluation of Lagenaria siceraria fruits can give some useful information, which will be further used for standardization.
