How do you identify cinnamic acid?
Cinnamic acid is an organic compound with the formula C6H5CH=CHCOOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants.
Is cinnamic acid a polyphenol?
Cinnamic acids are one of the major classes of phenolic compounds found in nature, including common caffeic acid, p-coumaric acid and ferulic acid (Herrmann, 1989). They showed antibacterial activity against both gram-positive and gram-negative bacteria.
What happens when cinnamic acid is heated?
Pyrolysis of cinnamic acids led to the formation of styrenes. Heating of ethyl cinnamate in H2O at 220 °C led to the formation of styrene in good yield <1997JOC2505>. Decarboxylation of cinnamic acid derivatives was reported by using plant cell cultures.
Where can cinnamic acid be found?
Cinnamic acid is naturally found in the spice cinnamon, which is derived from the bark of trees from the genus Cinnamomum. The main aromatic compound responsible for the flavor of cinnamon is cinnamyl aldehyde.
What foods contain cinnamic acid?
