GENERAL DESCRIPTION & APPLICATION
Polyphenols are referred to a group of phenolic compounds which have at least two hydroxy groups in one molecules found in plants. At a lower concentration than that of the oxidizable substrate, polyphenols act as primary antioxidants which inhibit or delay the oxidative processes by the donation of an electron or hydrogen atom, resulting in the protection of cells and body before cell damage caused by highly reactive free radicals and atoms. Polyphenols are components of flavonoids, plant pigments, flavours of plants. Polyphenols are taken application of free radical scavenging properties and chelating capacities for anti-aging and cancer prevention. Ferulic Acid, having two isomers: the cis form is a yellow oily liquid, and the trans form is crystalline, is a powerful membrane antioxidant to prevent free radicals in muscle tissue. It cab be used as an UV protection agent in skin-care products for anti-aging and anti-wrinkling.

cinnamic acid  is a key intermediate in shikimate and phenylpropanoid pathways. Shikimic acid is a precursor of many alkaloids, aromatic amino acids, and indole derivatives. Phenylpropanoid are a class of plant metabolites based on phenylalanine. They are widely distributed in plants fulfilling many functions including plant defense mechanism, pigmentation and external signaling system. Phenylalanine is first converted to cinnamates, coumarines, caffeic acids, ferulic acids, and sinapic acids. Cinnamic acid is the precursor of these acids. Cinnamic acid is the parent compound of its esters which are more volatile to be transported to other parts easily. Commercial cinnamic acid, a phenylacrylic acid structure compound, is used in converting to its esters such as methyl, ethyl, and benzyl cinnamate for the perfume and flavour application. Cinnamic acid and Its derivatives including esters and carboxylic functional derivatives are used as important components in flavours, perfumes, synthetic indigo and pharmaceuticals. Cinnamate can act as optical filters or deactivate substrate molecules that have been excited by light for the protection polymers and organic substances. They, cosmetic grades, are used as sunscreen agents to reduce skin damage by blocking UV-A, B. Cinnamic acid is an odorless white crystalline powder; slightly soluble in water; melting point 133 C and boiling point 300 C.
