Abstract: Nelumbo nucifera flower petals and seed extracts were evaluated for phytochemical constituents (flower petals and seeds) such as primary (carbohydrate, protein, fat) and secondary metabolites, flavonoids, phenols, tannins, steroids and glycosides. In addition, the nutritive value of the seeds were evaluated. The healing properties of the lotus plant is due to the presence of active principles such as phenolics, tannins, alkaloids, and flavanoids that are constitutents of many pharmacologically active compounds. The Flower petals and seeds were extracted in solvents used for the extraction viz., ethanol, ethylacetate, hexane, chloroform, Acetone and aqueous for phytochemical screening. Lotus fower petals and seeds extract recorded the presence of primary metabolites viz., carbohydrates, proteins and lipids and secondary metabolites such as phenols, flavanoids, tannins, alkaloids, sterols, terpenoids, cardiac glycosides, coumarin (Petals) and quionone (Petals). The quantification of primary metabolites of the extract indicates its nutritive value while the secondary metabolites are responsible for the medicinal properties of the lotus seeds and flower petals. Quantification of phytochemicals revealed that ethanolic extract of flower and seed has the maximum phenols, flavanoids and tannin content compared to other solvents. This study indicates that lotus seeds can serve as an alternate protein source as it possess potential nutritional and medicinal properties.
