What is Methyl cinnamate?
Description
Methyl cinnamate is the methyl ester of cinnamic acid and is a white or transparent solid with a strong, aromatic odor. It is found naturally in a variety of plants, including in fruits, like strawberry, and some culinary spices, such as Sichuan pepper and some varieties of basil. Eucalyptus olida has the highest known concentrations of methyl cinnamate (98 %) with a 2 - 6 % fresh weight yield in the leaf and twigs.
Methyl cinnamate is used in the flavor and perfume industries. The flavor is fruity and strawberry-like; and the odor is sweet, balsamic with fruity odor, reminiscent of cinnamon and strawberry.
It is known to attract males of various orchid bees, such as Aglae caerulea.
Methyl cinnamate crystals extracted using steam distillation from Eucalyptus olida.
Chemical properties
Methyl cinnamate has a fruity, balsamic odor similar to strawberry and a corresponding sweet taste.
Occurrence
Reported found in the oil from rhizomes of Alpinia malaccensis, in the oil from leaves of Ocimum canum Sims.; in the oil of Narcissus jonquilla L.; in the oil from rhizomes of Gastrochilus panduratum Ridl.; two isomers (cis- and trans-) exist in natural. Also reported found in cranberry, guava, pineapple, strawberry fruit and jam, cinnamon leaf, Camembert cheeses, cocoa, avocado, plum, prune, cloudberry, starfruit, plum brandy, rhubarb, beli (Aegle marmelos Correa), loquat and Bourbon vanilla.
The Uses of Methyl cinnamate
Methyl cinnamate is used as a fragrance ingredient in cosmetics and household products.
The Uses of Methyl cinnamate
Methyl cinnamate was used to inhibit monophenolase and diphenolase activity of mushroom tyrosinase and it also has antimicrobial ability. It is mainly is used in the flavor and perfume industries. It is known to attract males of various orchid bees, such as Aglae caerulea.
Preparation
Methyl cinnamate is synthesized by esterification of cinnamic acid with methanol using HCl as catalyst, or by adding HCl to a boiling solution of cinnamyl nitrile in methanol.
Definition
ChEBI: Methyl cinnamate is a methyl ester resulting from the formal condensation of methyl cinnamic acid with methanol. It is found naturally in the essential oils of Alpinia and Basil leaf oil, and widely used in the flavor and perfume industries. It has a role as a flavouring agent, a fragrance, an insect attractant, a volatile oil component and an anti-inflammatory agent. It is a methyl ester and an alkyl cinnamate.
