[0028] Put the camellia oleifera cake in a carbonization furnace, and fill the furnace with nitrogen gas at a rate of 60mL / min. At a temperature of 550°C and under the protection of nitrogen gas, keep warm for 30 minutes and then cool down to room temperature with the furnace to obtain carbonization. Camellia oleifera cake is placed in a pulverizer to pulverize carbonized tea oleifera cake, and passes through an 80-mesh sieve to obtain carbonized tea cake powder; in parts by weight, 40 parts of carbonized tea cake powder, 60 parts of dehydrated methanol, and 60 parts of dehydrated ethanol Place in a single-necked flask with a spherical condenser, heat to reflux and stir and mix at a temperature of 100°C and a rotational speed of 500r / min to obtain a mixed solution, then filter the mixed solution to obtain a filtrate, and then place the filtrate in a rotating In the evaporator, under the conditions of temperature 100°C, rotation speed 80r / min, and pressure 600kPa, concentrate un...
