Abstract

Sun light is the major source of U.Vradiation; it extends to the earth’s atmosphere and helps our body to synthesize vitamin D, which promotes the bone growth. But due to high exposure to U.V radiation from sun may cause sunburns, wrinkles etc. The UV-A penetrates the skin and causes premature ageing of skin, UV-B mostly causes sunburns and damage to DNA in skin. The present study was aimed to evaluate the U.V absorption ability of aqueous extracts of fresh and dry leaves of crossandra infundibuliformis as an Anti-solar agent. U.V visible spectrophotometer is used to perform this method. The results shown that aqueous fresh leaves extract of C. infundibuliformis has better Anti-solar activity than dry leaves extract. As it contains natural flavanoids and polyphenols they are considered as excellent sunscreen agents. Therefore it was concluded that C.infundibuliformis leaves extract can be used in preparation of various highly effective sunscreen formulations as it provides the better advantage of avoiding the harmful effects of synthetic sunscreen preparations.

Keywords: Anti-solar, crossandra infundibuliformis, UV radiation, U.V visible spectrophotometer.
