Abstract: Leaves of six kinds of tree that planted extensively in south China as well as fruit pomaces of 5 kinds of conventional fruit were selected to be extracted with 50%(vol) ethanol aqueous solution under ultrasonic wave assistance.The extracts were blended based upon their UV absorbing spectra and to be used in formulating sunscreen creams.Test results showed that in case the mass concentration is 0.2 g·L^-1,average UV absorbance of the leaves of mango tree achieves 1.248 while that of both orange pomaces and grape pomaces achieves near or more than 1.0.The blend was formulated in accordance with m(grape pomaces) : m(orange pomaces) :m(mango tree leaves) = 1:4:5,and blend dosage in the sunscreen cream product is 10 mL of extract blend in 100 g of cream base.The product displays good sunscreening efficacy.
