| titleOfInvention | Multistep extraction method of rose polyphenols |
| abstract | The invention discloses a multistep extraction method of rose polyphenols. The method comprises the following steps: 1. taking a rose petal fresh material, cleaning, chopping, drying, putting into an ethanol solution, soaking, filtering, and concentrating to obtain a concentrated solution 1; 2. putting in an ethanol solution again, carrying out ultrasonic treatment, filtering, and concentrating to obtain a concentrated solution 2; 3. uniformly mixing the concentrated solution 1 and concentrated solution 2, centrifugating, standing, and extracting to obtain a supernate 3; 4. adding the supernate 3 into a polar macroporous adsorbent resin chromatographic column, carrying out adsorptive separation, eluting with an ethanol solution, and concentrating to obtain an extracting solution 4; and 5. carrying out vacuum drying or microwave drying on the extracting solution 4 to obtain the rose polyphenol extract. Hot dipping, ultrasonic treatment, centrifugation, chromatography and other technical means are adopted, and multiple extraction steps are performed, thereby maximally extracting the rose polyphenols contained in the roses. The method has the advantages of high efficiency and high extraction yield. |
