| titleOfInvention | A kind of microwave-assisted method for extracting total alkaloids in Aconitum alba |
| abstract | The invention discloses a method for microwave-assisted extraction of total alkaloids of Aconitum aconite, which comprises the following steps: 1) raw material pretreatment: drying and pulverizing the raw material of Aconitum aconitum powder, sieving the product, and taking the fine powder as a raw material for processing Extraction; 2) Ultrasonic extraction: prepare a certain concentration of ethanol as the extraction solvent, first add hydrochloric acid with a concentration of 1-2% to the extraction solvent to adjust the pH=2-6 of the mixed solvent, and then use the aconite powder obtained in step 1) Fully mix with the mixed solvent, stand for immersion for 20-60min, extract for 2-10min at a microwave power of 700-900W, filter out insoluble matter to obtain a filtrate; 3) repeat the extraction process of step 2) 0-3 times, Combine several extraction filtrates to obtain the final filtrate. The invention has the advantages of simple and quick operation, high extraction rate, high speed, high efficiency and energy saving. |
