Embodiment 1
[0046] The preparation method of embodiment 1 and embodiment 3 is:
[0047] (1) Preparation of green bamboo essential oil
[0048] S1: drying and pulverizing the bamboo leaves to obtain bamboo powder with a particle size of 10 mesh;
[0049] S2: adding the bamboo powder into water at a weight ratio of 1:20 for soaking for 2 hours to obtain a mixture to be extracted;
[0050] S3: adding the mixture to be extracted into a distillation pot filled with n-hexane for distillation, the distillation time is 4 hours, and the distillation temperature is 55°C to obtain oil-water mixed steam;
[0051] S4: Condensing the oil-water mixed steam through a condenser to obtain an oil-water mixture;
[0052] S5: After the oil-water mixture is dried and dehydrated with anhydrous sodium sulfate, the anhydrous sodium sulfate is filtered to obtain a filtrate;
[0053] S6: Concentrate the filtrate under reduced pressure to remove the organic solvent by rotary evaporation at a temperature of 35° C....
