Lotus is traditionally used as antibacterial, diuretic, uterotonic, antidiabetic, hematemesis, anti-inflammatory etc. The plant is rhizomatous aquatic herb widely distributed in temperate and tropical climates around the world. The family Nymphaeaceae consists of 8 genera, 100 species distributed all over the world of which 4 genera and 7 species occurring throughout India. In the present study, the two varieties of lotus (pink and white flowers) were compared. The preliminary phytochemical analysis revealed the presence of alkaloids, carbohydrates, saponins, phenols, flavonoids, amino acids, protein, diterpenes, tannins, terpenoids, steroids, oxalate, cardiac glycosides, anthocyanin, carboxylic acid, xanthoprotein, coumarin, quinines, glycosides and leucoanthocyanin.
