In-vitro Sun Protection Activities of different Solvent Extracts of Pistia stratiotes leaves

Ageing is a normal, expected, and natural aspect of life. Ageing causes a body to change gradually or sequentially, increase health problems. The changing nature of our lifestyle has made ageing a prevalent issue. There are numerous chemical formulations available on the market today, but they all have drawbacks. Plant extracts those have antioxidant properties and rich source of flavonoids have ability to absorb UV rays these plants drawn attention as potential sunscreen ingredients recently. The aim of the current work is to examine the Sun Protection Factor (SPF) activity of various Pistia stratiotes leaf extracts. Sunscreens also contain chemical bases protect the skin from ultraviolet radiation, or light beams from the sun. Sometimes, exposure to these synthetic materials may result in skin hypersensitivity. Using plant-based creams and lotions is used to protect skin from chemical and photoallergic reactions. Using the Mansur formula, the Sun Protection Factor (SPF) of chloroform, ethanol, and aqueous extracts of Pistia stratiotes leaves was measured between 290 and 320 nm. The SPF values that were computed fell between 1.225 to 3.567. The ethanol extract of Pistia stratiotes leaves exhibited the highest SPF activity among the three extracts employed in this investigation, surpassing that of the other two extracts. The result may be due to the pro-oxidant effect of these chemicals, rather than their antioxidant effect. This study suggests that different ratios and combinations of the extracts could be utilized to create photoprotective products with synergistic or additive effects.
