ABSTRACT
Medicinal plants are natural gift to human lives to promote disease free healthy life. The phytochemicals present in leaf, fruits and vegetables could reduce various risks of diseases owing to prevent the oxidative damage produced by free radicals. The plant seed also contain many active molecules responsible for various medicinal properties. N.nucifera, E,officinalis, M. oleifera, T.chebula, T.bellerica and flax seed oils are tested for SPF determination by in vitro method. The seed oils had shown very good SPF values. E.officinalis seed showed 25.77 as Sun Protection Factor (SPF) value and N.nucifera seed Cotyledon had 21.45 SPF values which was quite high when comparing other seed oils. This study supports the usage of seed oil as a UVB sun screen protector, an alternative source of nutrition and as well as renewable resources.
