ESTIMATION OF PHYTOCHEMICALS AND SUN PROTECTION FACTOR (SPF) NUMBER IN COMMONLY USED ETHANOLIC HERBAL EXTRACTS

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.
