Study On The Flavonoids Extraction Method From Propolis And Optimized The Extraction Process

Propolis is a high flavonoid content of the material; it has anti-aging, anti-oxidation,anti-bacterial, lower blood pressure, hypoglycemic a series of pharmacological functionand health function. To enable the propolis flavonoids play an even greater social andeconomic benefits, improved extraction technology propolis, increase the extraction rateand lower production costs is an urgent need to resolve problems. In recent years, it wouldimprove the natural products as a powerful tool for extraction with the microwaveextraction technology. Microwave rapid and selective heating characteristic of this paperuse of microwave extraction of propolis,to improve the propolis extract and flavonoids inthe rate of extraction rate.This paper investigated the type of solvent extraction, microwave power, microwaveirradiation time, solvent concentration, and the volume of alcohol than on a series offactors such as propolis flavonoids extraction rate impact. The trial of rutin standardsolution Spectrophotometric Determination of flavonoids extracts the content of flavonoidsextraction rate calculation. In reference to the traditional production process, on the basisof the introduction of the process of extraction of microwave links, these two extractionmethods should get organic together. Through testing, it determined the solvent extractionconditions. The level of alcohol concentration of propolis flavonoids extraction rate is verysignificant, microwave irradiation time for the length of propolis flavonoids extraction rateis significant. Microwave Power Propolis the size of the extraction rate of significant, butfeed on propolis flavonoids than the rate of extraction is not significant. Orthogonal designmicrowave extraction methods to identify the optimal combination. Within theexperimental results showed that when microwave power of 800 W and microwave for 1.5min, ethanol concentration of 80%, the feed ratio is 1:10, propolis flavonoids extractionrate of up to 31.32%. More than the conventional method of extracting ethanol extractionrate of flavonoids was up nearly 10%; the time is shortened by 2/3.Experimental results show that microwave extraction technology use, making propolisyield increased 3.83%. Flavonoids the extraction rate will be increased by 8.22%, while theamount of ethanol only traditional arts and 1/2, shorten production time by nearly 2/3. Inthe experiments on microwave extraction equipment, and industrial production applicationof the study, to transform the domestic microwave ovens, Microwave can be achievedpropolis extract flavonoids production needs, and easy to operate, low-cost, small investment. For the future, microwave extraction equipment provided for the developmentof new ideas.
