This invention relates to novel resveratrol analogs of the formula given below; wherein R, R1, R2 and R3 are: 1. R=OH, R1=R2=R3=H; 2. R=0H, R1=Br, R2=R3=H; 3. R=R1=0H, R2=R3=H; 4. R=R1=R3=H, R2=3,4,5-trihydroxybenzoyl; 5. R=R1=H, R2=R3=3,4,5-trihydroxybenzoyl; 6. R=R1=R3=H, R2=3,4-dihydroxycinnamoyl; 7. R=R1=R3=H, R2=3,4,5-trihydroxycinnamoyl; 8. R=R1=R3=H, R2=-CH2CH2N(CH3)2; 9. R=R1=R3=H, R2=-COCH2NH2.HC1. These compounds exhibited high antioxidant properties and are useful in food industry and in cosmetics. The compounds may be used in pharmaceutical composition as an antioxidant or free radical scavenger.
