An in-vitro evaluation of skin protection factor of non-polar date seed extract from three different date varieties Ajwa, Aseel and Khapra by UV spectrophotometry

Abstract

Objective: Skin is the primary layer of human body which act as protective barrier against exogenous chemicals, UV radiations as well as microorganisms. Maintaining the skin morphology under regular environmental stresses and controlling age related skin changes is one of the biggest challenges for modern science, pharmaceutical and cosmetics industry. These environmental stresses, such as excessive exposure to UV radiations, can even lead to the devastating skin disorders such as skin cancer. Dates seed has capability to protect skin against the damages caused by solar radiations, which mostly appear in the forms of wrinkles and some other skin related issues. Methods: Therefore, current research is focused on to analyze sun protection factor (SPF) of two non-polar fractions obtained from crushed seeds of three different varieties of i.e., Ajwa, Aseel and Khapra. Results: Results indicate that the highest value of SPF was found in AEA i.e., 15.061 at 200ppm while no difference was observed in the SPF values of KPPE. Conclusion: Hence, it could be concluded that the ethyl acetate fraction of all date seed varieties could be potential Ajwa, Aseel and Khapra could be a promising source of cosmetic and pharmaceutical preparations due to the potential SPF value except petroleum ether of Khapra extract.
