Use
It is also known as 1, 2-benzopyrone, cis ortho-caberillin, o-hydroxy cinnamon lactone and coumarin. It is contained in many natural plants in the form of glycosides and esters as vanillin instead of free-form. Coumarin will come out when certain plants are fermented and processed. Coumarin is found in the seeds of Dayton beans (Riccinechoides) in 1820 and is widely distributed in the plant kingdom, especially in plant species including Umbelliferae, Soybean, Rutaceae and Calyx. Seeds contain about 1.5% of the coumarin. In addition, coumarin is also contained in lavender oil, cinnamon oil and Peru balsam. Coumarin is spicy with sweet and lemongrass aroma. The aroma is emitted from the pink gum in the leaves of the fragrant beans, and the gum is made from the breakdown of the coumarin glycosides in the leaves. The aroma emitted by Sweet alfalfa is actually from the release of coumarin due to fermentation and decomposition during the stacking process. Precipitate from the ether appears as orthorhombic white pyramid or oblique sheet-like crystals with Lemongrass-type smell. It can subject to sublimation.
