There are two isomers of myrcene: Alpha myrcene and B- myrcene, and B myrcene is mainly found in nature. In the distillate of Phellodendron amurense leaves and Bursa rugosa leaves, the content can reach 50% and 40%, respectively. In addition, in cinnamon oil, maple grass oil, cedar oil, spruce oil, turpentine, verbena oil, lemon grass oil, lemon oil is also present. B- myrcene is a colorless or yellowish liquid with a light balsam aroma. Soluble in ethyl acetate, benzene, ether, petroleum ether and other organic solvents. Molecular weight 136. 24, boiling point 166~168 ℃, relative density of 0.8013, refractive index of 1. 4650.
The distillate from the leaves of Phellodendron amurense L. Or sofumox leaves was separated by distillation. Or from B- pinene pyrolysis.
can be used for the preparation of food flavor. Or for the synthesis of linalool, geraniol, nerol, citronellol, citronellal, ionone and other compounds of raw materials.
