[0029] A preparation method of Caoguo volatile oil antiemetic spray, comprising the following steps:
[0030] Step 1. Soak the grass fruit in a starch solution with a concentration ratio of 1% by mass for 2 hours, then soak it in clean water for 30 minutes, freeze-dry the grass fruit soaked in clean water and crush to obtain the grass fruit freeze-dried powder, and make the grass fruit jelly After passing through a 40-mesh sieve, the dry powder is put into the extraction kettle of a supercritical carbon dioxide extraction device. After extraction for 90 minutes under the conditions of extraction temperature of 45°C, extraction pressure of 18MPa, and carbon dioxide flow rate of 88L / h, the extract is released from the separation kettle , to obtain Tsaoguo volatile oil;
[0031] Step 2. Wash the ginger and cut it into slices of 2 cm in thickness. Soak the slices in culture solutions with initial concentrations of 800 CFU / ml and 300 CFU / ml of Citrobacter fischeri and Lactobacillus...
