How is cinnamic acid produced?
It is obtained from oil of cinnamon, or from balsams such as storax. It is also found in shea butter. Cinnamic acid has a honey-like odor; 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.
What plants contain cinnamic acid?
In addition, cinnamic acid can be generally obtained from cinnamon (Cinnamomum cassia (L.) J. Presl), citrus fruits, grape (Vitis vinifera L.), tea (Camellia sinensis (L.) Kuntze), cocoa (Theobroma cacao L.), spinach (Spinacia oleracea L.), celery (Apium graveolens L.), and brassicas vegetables [18].

What is cinnamic acid derivatives?
The common cinnamic acid derivatives include p-coumaric acid, caffeic acid, and ferulic acid. Chokeberry is abundant in hydroxycinnamic acid derivatives represented mainly by chlorogenic acid and neochlorogenic acid. Ellagic acid and its conjugates form the majority of phenolic acids in red raspberries.
What foods contain cinnamic acid?
Cinnamic acid is found in a variety of plant sources, including cinnamon bark and its products, ginseng, fruits, vegetables, honey, and whole grains such as rice, wheat bran, and cereal grains.
Is cinnamic acid a fatty acid?
Cinnamic acid, a naturally occurring aromatic fatty acid of low toxicity, has a long history of human exposure. We now show that cinnamic acid induces cytostasis and a reversal of malignant properties of human tumor cells in vitro.
Is cinnamic acid toxic?
Cinnamic acid is a compound of low toxicity, but its molecular structure and the known toxicity of similar molecules, such as styrene, have brought it to the toxicologist’s attention.
Why is cinnamic acid acidic?
These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. Cinnamic acid can exist in both the cis and trans form, with the trans-form being most common. Trans-cinnamic acid is a weakly acidic compound (based on its pKa).
What is the use of cinnamic acid?
trans-Cinnamic acid is used in the manufacture of flavors, dyes, and pharmaceuticals; but its major use is for the production of its methyl, ethyl, and benzyl esters. These esters are important components of perfumes. The acid is also a precursor to the sweetener aspartame.
Does cinnamic acid dissolve in water?
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.
What is structure of cinnamic acid?
Is cinnamic acid aliphatic or aromatic?
trans-Cinnamic acid, also known as (e)-cinnamic acid or phenylacrylic acid, belongs to the class of organic compounds known as cinnamic acids. These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid.
What element is present in cinnamic acid?
Cinnamic acid is a monocarboxylic acid that consists of acrylic acid bearing a phenyl substituent at the 3-position. It is found in Cinnamomum cassia. It has a role as a plant metabolite. It is a member of styrenes and a member of cinnamic acids.
How do you identify cinnamic acid?
Cinnamic acid is a white crystalline acid with a molecular formula C9H8O2. It is a crystalline compound that is white in colour and is slightly soluble in water. It is collected from the oil of cinnamon and is also found in shea butter. It has a honey-like odour.
What does cinnamic acid smell like?
The olfactory examination of the compounds showed that all compounds smell like cinnamon, but hold also an amber note; they are fruity and to some extend balsamic.
Is cinnamic acid saturated or unsaturated?
Cinnamic acid, an unsaturated carboxylic acid, is the chief constituent of the fragrant balsamic resin storax.
Is cinnamic acid soluble in ether?
Its biosynthesis is performed by action of the enzyme phenylalanine ammonia lysase (PAL) on phenylalanine. Cinnamic acid is soluble in diethyl ether, insoluble in hexane.
What is Colour of benzoic acid?
Benzoic acid /bɛnˈzoʊ. ɪk/ is a white (or colorless) solid with the formula C6H5CO2H. It is the simplest aromatic carboxylic acid.
What is the melting point of cinnamic acid?
How do you make benzoic acid?
Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. The process is catalyzed by cobalt or manganese naphthenates. The process uses cheap raw materials proceeds in high yield, and is considered environmentally green.
What does cinnamic mean?
: a white crystalline odorless acid C9H8O2 found especially in cinnamon oil and storax.
How cinnamic acid is synthesis from benzaldehyde?
Cinnamic acid was prepared by oxidation of benzalacetone which was synthesized by condensing benzaldehyde and acetone. For producing benzalacetone, benzaldehyde was reacted with acetone in 1% NaOH solution. The yield was 88.8% of the theoretical.
Is benzoic acid an organic compound?
benzoic acid, a white, crystalline organic compound belonging to the family of carboxylic acids, widely used as a food preservative and in the manufacture of various cosmetics, dyes, plastics, and insect repellents.
Is cinnamic acid soluble in Naoh?
trans-Cinnamic acid contains two functional groups, a carboxylic acid and an alkene. Carboxylic acids undergo acid base reactions to form water soluble carboxylate salts with bases such as sodium hydroxide.
Is cinnamic acid soluble in ethanol?
It is soluble in ethanol, methanol, petroleum ether and chloroform; it is easily soluble in benzene, ether, acetone, acetic acid, carbon disulfide and oils but insoluble in water. Cinnamic acid was first isolated as crystals from cinnamon oil by Trommsdorf in 1780.
What is the density of cinnamic acid?

Where is benzoic acid used?
Benzoic acid is most commonly found in industrial settings to manufacture a wide variety of products such as perfumes, dyes, topical medications and insect repellents. Benzoic acid’s salt (sodium benzoate) is commonly used as a pH adjustor and preservative in food, preventing the growth of microbes to keep food safe.
Who discovered benzoic acid?
The sixteenth century saw the discovery of benzoic acid with Nostradamus (1556) first describing the dry distillation of gum benzoin, followed by Alexius Pedemontanus (1560) and Blaise de Vigenère (1596), but it was Justus von Liebig and Friedrich Wöhler determined the chemical structure.
Are you pack name of cinnamic acid?
The cinnamic acid IUPAC name is (2E)-3-Phenylprop-2-enoic acid.
Where is benzoic acid found in nature?
Benzoic acid naturally occurs in cranberries, prunes, strawberries, apples and yogurts (Chipley, 1993). In certain foods, benzoate may impart a disagreeable taste described as ‘peppery’ or burning.
What is benzoic acid good for?
As a kind of antibacterial and antifungal preservative, benzoic acid is widely used in foods and feeds. Recently, many studies showed that it could improve the growth and health, which should, at least partially, be derived from the promotion of gut functions, including digestion, absorption, and barrier.
Is benzoic acid good for skin?
Benzoic acid helps prevent infection caused by bacteria. Salicylic acid helps the body shed rough or dead skin cells. Benzoic acid and salicylic acid topical (for the skin) is a combination medicine used to treat skin irritation and inflammation caused by burns, insect bites, fungal infections, or eczema.
