Description:
Synthesis and preliminary evaluation of 4,4�-dihydroxy-3,3�-dimethoxydibenzylideneacetone (DDB) as
sunscreen and antioxidant have been successfully conducted. The compound was prepared through an acid
catalyzed condensation reaction between vanillin and acetone using saturated HCl solution in glacial acetic
acid. Pre-evaluation of sunscreen active compound candidate was performed by determining electronic
absorbance profile, max, , c, UVA/UVB ratio, and photostability while antioxidant activity test was
performed using DPPH radical scavenger method. Based on the results, the compound obtained has very
good protective effect in UVA region with high antioxidant activity.
