| titleOfInvention | Method for extracting chrysin from passiflora edulis fruit residue obtained after juicing |
| abstract | The invention discloses a method for extracting chrysin from passiflora edulis fruit residue obtained after juicing, which comprises: adding chrysin from passiflora edulis fruit residue obtained after juicing into low-carbon alcohol, regulating the pH value of the obtained mixed solution to 9 to 12 by using alkaline solution, and performing refluxing extraction for 1 to 3 times, 1 to 2 hours each time; combining extracting solution, cooling and pumping under vacuum; regulating the pH value of the filtrate to 1 to 3 by using an acid; standing, precipitating, and filtering under vacuum; dissolving a filter cake in ethyl acetate, filtering, and concentrating filtrate to obtain extract; adding low-carbon alcohol into the extract and regulating the pH value to 9 to 12 by using alkaline solution, heating, dissolving and cooling; regulating the pH value to 5 to 7 by using an acid, standing, precipitating, and filtering under vacuum; and washing an obtained filter cake, dying and thus obtaining chrysin. In the method disclosed by the invention, the juiced passiflora edulis fruit residue treated as a waste is used as a raw material for extraction, so the waste is recycled and resources are saved effectively; and the production method disclosed by the invention is low in production cost, makes a process simple and easy to control, requires short production period and is suitable for industrial production. |
