Cinnamic acid, a naturally occurring aromatic fatty acid of low toxicity, has a long history of human exposure. trans-Cinnamic acid is an α,β-unsaturated aromatic acid that can be used as a flavoring agent. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. It is mainly used in flavor and fragrance, food additives, pharmaceutical industry, beauty, pesticides, organic synthesis, etc. It is an organic acid isolated from cinnamon bark or benzoin. Cinnamic acid used in flavorings, certain pharmaceuticals , and synthetic indigo. The acid can exist as both trans and cis isomers; however it is the cis form that most people use today as it can be easily derived from a chemical reaction between benzaldehyde and acetic anhydride. Moreover, some currently investigated natural and synthetic derivatives of cinnamic acid have shown skin lightening and anti-ageing properties. Code : #4756 S 20 mg TLC and 1H NMR analysis confirm the purity of final product, without any cinnamic acid contamination, and thus it is not necessary to make any recrystallization. We now show that cinnamic acid induces cytostasis and a reversal of malignant properties of human tumor cells in vitro.

Accordingly, oral cinnamic acid also normalized striatal neurotransmitters and improved locomotor activities in MPTP-intoxicated mice. The oldest commercially used route to cinnamic acid involves the Perkin reaction, which is given in the following scheme[5], Cinnamic acid is used in flavorings, synthetic indigo, and certain pharmaceuticals. Cinnamic acid deriv. The lack of data on cinnamic acid makes identifying the body systems that it supports difficult. Rosmarinic acid (RosA) ( 3 ), a secondary metabolite in rosemary and basil, is used in the traditional treatment of inflammatory disorders such as arthritis. Cinnamic acid uses. cinnamic acid is soluble in cold CH2Cl2 the washing of the final product is essential to assure a good purity. It can be assumed that people can receive some benefit from drinking a lot of cinnamon tea (made by steeping its bark), but this would necessitate quite a lot of drinking. Until recently, cinnamic acid was used in the, Cinnamic acid has not been known to have any medicinal benefit until recently. Cinnamic acid is a derived compound that has been used as a flavor enhancer or as a crucial component in perfumes. It is used in the manufacture of methyl, ethyl, and benzyl esters for perfume industry. In the present work, we evaluated its effects on growth, indole-3-acetic acid (IAA) oxidase and cinnamate 4-hydroxylase (C4H) activities and lignin monomer composition in soybean (Glycine max) roots. Cinnamic acid is used in the flavors, synthetic indigo and certain pharmaceuticals. Needless to say, it is possible according to the invention to use cinnamic acid or its derivatives alone or as a mixture. It exists as both a cis and a trans isomer, although the latter is more common. Cinnamic acid is helpful in providing flowers with their bright colors, butterflies with their colorful wings, and gives fall leaves their distinguishable color. Research into this area, though, is limited and nothing can be conclusively stated regarding this supposed effect. The acid is also a precursor to the sweetener aspartame. Cinnamic acid has a honey-like odor;[2] it and its more volatile ethyl ester (ethyl cinnamate) are flavor components in the essential oil of cinnamon, in which related cinnamaldehyde is the major constituent.

[4] Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. Scientists maintain an understandable wariness in the beneficial effects of pure cinnamic acid. Cinnamic acid. Here, we add cis-cinnamic acid (c-CA) to the small portfolio of existing plant growth stimulators. Another study which used mice models saw that cinnamic acid improved glucose tolerance by promoting insulin secretion. Molecular Weight 148.16 . Its uses for medicine have only been studied recently.

Cinnamic acid (CA) and its hydroxy-derivatives are aromatic building blocks whose structural peculiarities (unsaturation, hydroxylic and/or carboxylic groups) have driven them to a prominent position in polymer science. [5], Cinnamic acid is a central intermediate in the biosynthesis of a myriad of natural products including lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. Based on the available literature, this broad range of usage of cinnamic acid derivatives might be extended by skin lightening and anti‐ageing functions. [7] Another way of preparing cinnamic acid is by the Knoevenagel condensation reaction. They have a wide distribution among fruits, vegetables, and beverages (e.g., tea, coffee) ( Lende et al., 2011 ).
