In vitro Evaluation of Sun Protection factor and Diffusion study of Hibiscus rosa-sinensis L. flower Extract Gel

In the present study, to investigates the in vitro sun protection factor (SPF) of Hibiscus rosa-sinensis Linn flower extract in a gel formulation. Due to its antioxidant and photo protective properties, Hibiscus rosa-sinensis Linn is a promising candidate for use in cosmetic and pharmaceutical formulations. The sun protection factors were analyzed by ultraviolet (UV) spectrophotometry using samples irradiated with UVB lamp. It is screened for In vitro sun protection factor in the Hibiscus rosa-sinensis Linn extract and of its gel formulation and determines Photo stability of the isolated Hibiscus rosa-sinensis Linn extract and SPF. This study has shown that the Hibiscus rosa-sinensis Linn fruit extract gel is stable for at least 2 to 3 months when stored at 5 and 25°C. The diffusion studies of the prepared gels can be carrying out in Franz diffusion cell for studying the dissolution release of gels through a cellophane membrane. This proved activity of plant showed its importance and prophylactic utility in anti-solar formulation. This will be a better, cheaper and safe alternative to harmful chemical sunscreens that used now a day in the industry.
