[0014] Shell and separate camellia oleifera fruit, weigh 300g of camellia oleifera seeds, put them in an oven and dry for 1h, and obtain 293.8g of camellia oleifera seeds after cooling, crush the dried camellia oleifera seeds to 50 mesh, add to the extraction kettle, and extract under supercritical CO? It is: temperature 45 ℃, pressure 30 MPa, CO flow rate 120 L / h, extraction 2h, the light yellow transparent camellia oil obtained by supercritical extraction is collected in the separation tank, its mass is 88.9 g, and the extraction rate of camellia oil is 29.63%.
[0015] Adjust the supercritical extraction conditions, the pressure is 20 MPa, and the temperature is constant, add 70% ethanol aqueous solution to the extraction kettle at a rate of 0.03 L / h, extract for 1.5 h, and collect the extract in the separation tank. The method of rotary evaporation was used to remove the entraining agent in the extract at 55 °C to obtain a light yellow powdery solid of camellia oleifera po...
