Cucurbita maxima peel contains carotenes and Curcuma Longa rhizomes contain curcumin as natural pigments. Curcumin has numerous health benefits such as antioxidant, anti-inflammatory, anti-diabetic, immune boosting capacity, anti-cancer activities etc. Curcumin is a bioactive compound, and it has strong medicinal properties. Carotenes have different biological roles like strong antioxidant properties, helps in maintaining proper vision and good skin health, support in improving immune function, etc. Curcumin and carotenes are used as natural dye in fabrics and food materials. This study mainly focused on the extraction of natural pigments from peel of Cucurbita maxima and rhizome of Curcuma longa using an ultrasonic extraction technique. Cucurbita maxima peel contained significant amount of carotenoids. The principle-coloured component in dyestuff extracted from pumpkin peel is β-carotene. Extraction was done by using sunflower oil as green solvent. The extracted pigment was analysed by FTIR and UV Visible Spectroscopy. Copyright@ International Science Community Association
