Embodiment 1
[0031] The invention provides a method for extracting camphor leaf essential oil, which is carried out in the following steps:
[0032] (1) Drying: put the camphor leaves at room temperature and dry them in the shade out of light until the water content is 3%.
[0033] (2) Pulverization: pulverize the dried camphor tree leaves with a pulverizer, and pass through a 20-mesh sieve to obtain camphor camphor leaf powder.
[0034] (3) Enzymolysis: Add appropriate amount of water and cellulase to the camphor leaf powder obtained in step (2), the mass ratio of the added water to the camphor leaf powder is 8:1, and the consumption of the cellulase is 0.5 %, after stirring evenly, place it in a water bath at 45°C for 1 h, and keep stirring during this period.
[0035] (4) Simultaneous distillation and extraction: the connection is as good as figure 1 The simultaneous distillation and extraction device shown in the figure performs simultaneous distillation and extraction on the mixture...

[0040] The invention provides a method for extracting camphor leaf essential oil, which is carried out in the following steps:
[0041] (1) Drying: place the leaves of the camphor tree at room temperature and dry in the shade out of light until the water content is 4%.
[0042] (2) Pulverization: pulverize the leaves of camphor oleifera dried in the shade with a pulverizer, and pass through a 40-mesh sieve to obtain camphor leaf powder.
[0043] (3) Enzymolysis: Add appropriate amount of water and cellulase to the camphor leaf powder obtained in step (2), the mass ratio of the added water to the camphor leaf powder is 9:1, and the consumption of the cellulase is 0.6 %, after stirring evenly, place it in a water bath at 45°C for 1 h, and keep stirring during this period.
[0044] (4) Simultaneous distillation and extraction: the connection is as good as figure 1 The simultaneous distillation and extraction device shown, the specific steps are the same as in Example 1. The mixtu...
Embodiment 3
[0049] The invention provides a method for extracting camphor leaf essential oil, which is carried out in the following steps:
[0050] (1) Drying: place the leaves of camphor oleifera at room temperature and dry in the shade out of light until the water content is 5%.
[0051] (2) Pulverization: pulverize the dried camphor tree leaves with a pulverizer, and pass through a 60-mesh sieve to obtain camphor camphor leaf powder.
[0052] (3) Enzymolysis: Add appropriate amount of water and cellulase to the camphor leaf powder obtained in step (2), the mass ratio of the added water to the camphor leaf powder is 10:1, and the consumption of the cellulase is 0.6 %, after stirring evenly, place it in a water bath at 45°C for 1 h, and keep stirring during this period.
[0053] (4) Simultaneous distillation and extraction: the connection is as good as figure 1 The simultaneous distillation and extraction device shown, the specific steps are the same as in Example 1, the mixture obtain...
