| titleOfInvention | A kind of extracting method of betel oil |
| abstract | The present invention relates to a kind of extracting methods of betel oil.Its processing step includes: to weigh the raw material 10-20g of crushing to be put into filtration paper cylinder, then paper tube is placed in Soxhlet extractor, and 100mL organic solvent is added, Soxhlet extractor is mounted on thermostat water bath, bath temperature is set by different organic solvents, is condensed back, controls reflow's cycle in 12 times/h.After extraction, stops heating and after cooling, extract will be mixed and be transferred in rotary evaporator and be distilled to recover organic solvent, obtain betel oil after concentrate vacuum freeze drying.The method has the advantages that equipment is simple, easy to operate, low cost compared with conventional method. |
