Recovery Optimization of Plant Derived Antioxidants And Their Incorporation in Cosmetic Creams to Enhance Antioxidant Potential

Abstract

Plants waste is enriched with valuable antioxidants. Extraction optimization, quantification of Total phenolic content (TPC) and evaluation of their anti-aging potential was the prime goal of this research study. Lime, Neem, Radish leaves, and carrot pulp were extracted with two types of solvents under various extraction conditions. The highest TPC were extracted through boiling water (2-3min) for all plant materials as follow: Neem leaves (112.3mg GAE/g), Lime leaves (108.5mg GAE/g), Radish leaves (76.02mg GAE/g) and Carrot pulp (65.84mg GAE/g); Highest free radical scavenging activities were achieved in Neem Leaves (92.82%), Lime leaves (92.34%), Radish leaves (87.4%) and Carrot Pulp (81.22%) under different extraction conditions. Water as extraction solvent yielded greater TPC values than ethanol. Upon the addition of phytoextracts, a substantial increase in the antioxidant activity of the cream samples was detected. Upon loading 2% lime extract, one cream sample exhibited a rise in TPC content from 1.8 to 54.05mg GAE/g and antioxidant activity from 19.34% to 95.35%. Cream samples infused with phytoextracts also showed notable antimicrobial activities. Conclusively, waste derived phytoextracts can be cost-effectively utilized in formulation of skin anti-aging creams.
