摘要

The present invention relates to an extraction method for a lacquer liquid of leaves and seeds of a lacquer tree. According to a first embodiment of the present invention, the extraction method for a lacquer liquid of leaves and seeds of a lacquer tree comprises: a depositing step of depositing 100 parts by weight of lacquer tree leaves harvested before the leaves turn red, including budding, in one steep water selected among a steep water group comprising purified water, a saline solution, and persimmon vinegar for predetermined time; a first drying step of removing the lacquer tree leaves wet enough after completing the depositing step and firstly drying the lacquer tree leaves in the shade of a room temperature or by a dryer so that the lacquer tree leaves becomes 100-120 parts by weight; a grinding step of grinding the lacquer tree leaves dried after completing the first drying step; a second drying step of mixing 5-40 parts by weight of a mixture or a liquid selected among the purified water or raw lacquer to 100-120 parts by weight of the lacquer tree leaves ground after completing the grinding step, and secondly drying the same in the shade of the room temperature or by the dryer; a first toxicity removing step of removing toxicity by placing 100-120 parts by weight of the lacquer tree leaves into a tray of a pressure container after completing the second drying step, and by steaming the lacquer tree leaves for 1-3 hours at a temperature range of 120-160°C; a third drying step of thirdly drying the lacquer tree leaves steamed after completing the first toxicity removing step, in the shade of the room temperature or by the dryer so that the lacquer tree leaves is in the range of 100-120 parts by weight; and an extraction step of extracting 90-350 parts by weight of a distilled extract by secondly removing the toxicity remaining by heating a distiller to maintain an inner temperature of 140-200°C after placing the lacquer tree leaves maintaining 100-120 parts by weight after completing the third drying step into the upper side of the distiller containing 100-380 parts by weight of the water.;COPYRIGHT KIPO 2018
