In 1985, the records of the modern Chinese forestry show that in the southwest forest region, the broadleaf trees in Minjiang watershed have a large number of species, and the broad distribution of the species is provided with valuable tree species such as nanmu, camphor wood and the like. In 1974, by the research and identification of Zhao Liang in forest classification experts of scientific research institute of forestry, Sichuan province, the camphor trees specially produced in Sichuan province and western Shaanxi are new species, namely Cinnamomum camphora, the scientific name of the Cinnamomum longipanifolium (Gamble) N.Chao ex H.W.Li, the Cinnamomum camphora has the advantages of fast growth, strong germination, more leaves, straight and dry shape, beautiful tree shape, fresh leaves with fresh and cool fragrance and stuffy flavor, and rich aromatic oil.
The oil extracted from Cinnamomum camphora is Cinnamomum camphora oil, which is extracted from the leaves of Cinnamomum camphora (such as fresh leaves) without water loss by steam distillation, and is composed of dozens of chemical substances, and is a mixture. The extraction device is as shown in fig. 1, after fresh sassafras leaves are put into an extraction tank 1 from a feeding port 2, high-temperature water vapor enters the extraction tank 1 from a water vapor inlet 6 to flow upwards to be fully combined with the sassafras leaves for distillation, the distilled gas flows into a condenser separation system 4 from a gas outlet 3 at the top for condensation separation and then enters a collection tank 5 for collection, and the distilled condensed water is discharged from a condensed water outlet 7 at the bottom. The steam distillation of fig. 1 for extracting camphor oil has the following defects: the yield of the refined camphor oil is low.
The oil camphor oil extracted by steam distillation can be used for medicine, spice and the like after being refined, for example, the oil camphor oil can be used as a raw material of high-grade spice to synthesize various types of fragrance types such as lilac type, lilac type and the like. When the cinnamomum camphora oil extracted by steam distillation is provided as a raw material of medicines and spices, the following defects exist in the customer reaction: (1) the fragrance is far from the fresh camphor leaves, and the fragrance lacks the fresh and stuffy fresh camphor leaf taste. (2) After being applied to the skin, the absorption is poor.
