| titleOfInvention | A kind of method of microwave radiation exaraction valerian naphtha constituents |
| abstract | The invention discloses a kind of methods of microwave radiation exaraction valerian naphtha constituents, steps are as follows: valerian rhizome is crushed, it is put into round-bottomed flask, n-hexane is added, it is placed in microwave cavity and extracts 2-4 times, 30-40min is extracted every time, microwave power is 300-320W, it is cooled to room temperature after extraction, it filters, collect filtrate, concentration is concentrated under reduced pressure, water bath method obtains Microwave Extraction object, add NaCl solution, 7-9h is impregnated after shaking mixing, connect volatile oil determination apparatus and reflux condensing tube, keep slightly boiled, stop heating after distilling 5-7h, it stands, take volatile oil, anhydrous sodium sulfate is added to stay overnight, it filters to obtain the final product.This method is easy, quick, easy to operate, recovery rate is high, and the valerian naphtha of preparation has stronger Scavenging activity and higher reducing power to DPPH free radical, hydroxy radical, can be prepared on a large scale. |
