Abstract :

The aim of the present study is phytochemical screening and the ultraviolet absorption properties of ethanolic
herbal extracts of some commonly used vegetable sources by determining the sun protection factor (spf) number.
The invitro SPF number is determined according to the spectrophotomertic method described by Mansur et.al.,.
Ethanolic herbal extracts were prepared and after dilution with alcoholic solutions the absorbance were recorded
between 290-320 using uv-vis spectrophotometry. It was observed that all of the ethanolic herbal extract showed
some UV protection capability.
Keywords: sun protection factor, spectrophotomertic , ethanolic extract
