Description

Application

• 4-(Dimethylamino)cinnamaldehyde (DMAC) has been used in the serine protease inhibition assay.
• It has been used for the detection of (epi)-flavan-3-ols and proanthocyanidin polymers in Brassica napus seeds.
• It has been used for the determination of phenolic compounds in leaf samples.
• It has been used for the staining of flavan-3-ols in plant samples.

Biochem/physiol Actions

Reagent for assay of indole product of apotryptophanase and tryptophanase. DMAC produces colored adducts with flavanols for subsequent HPLC. It has been used in a chromogenic method for quantifying proanthocyandines in cranberry powder.
