생물학적 활성
Dibenzylideneacetone (DBA) showed inhibitory activity against Botrytis cinerea Chitinase with an IC50 of 13.10 μg/mL. The MIC of DBA against B. cinerea was 32 μg/mL, and the EC50 values for inhibition of hyphae growth and spore germination were 16.29 and 14.64 μg/mL, respectively. DBA was able to significantly extend the shelf life of cherry tomato shelf life and is a promising antifungal agent for fruit preservation[1].Purification Methods
Crystallise the ketone from hot ethyl acetate (2.5mL/g) or EtOH. [Beilstein 7 IV 1747.]Dibenzylideneacetone 준비 용품 및 원자재
