Method of extracting natural oxidationresistant active substanceoil from orange tree bark

Abstract

The invention relates to a method of extracting natural anti-oxidation active substance from plant materials, which discloses a method of extracting natural anti-oxidation active substance from oil orange tree bark. The method includes the following steps: (1) crushing; (2) extracting: the water is the solvent, the mass of the bark materials which have been crushed to the volume of water is 1 : 5g / ml to1: 10g / ml, the bark materials crushed are immersed in the water, the extracting solution is gained under the temperature ranging from 50 DEG C to 80 DEG C and under the effect of ultrasonic; (3) flocculating settling: the chitosan acetic acid solution is the flocculating agent; and the chitosan acetic acid solution is added into the extracting solution and stirred for 10 minutes to 30 minutes; (4) subzero fractionating: the extracting solution which is added with the flocculating agent is cooled and kept statically, the clear solution is extracted and the sediment is threw away; (5) theclear solution is added with 15 percent to 20 percent active carbon and 0.4 percent to 0.6 percent EDTA-2Na which are fixedly contained in the clear solution, the clear solution is filtered for the cleaning of the carbon after the clear solution is stirred for 0.5 hour to 1 hour, the filtrate is used as the upper-column liquid for the fractionation by adsorption of the resin; (6) fractionation byadsorption of the resin, by using desolvation, the powdered natural anti-oxidation active substance is gained by the vacuum freeze drying.

Description

technical field The invention relates to a method for extracting natural antioxidant active substances from plant materials, in particular to a method for extracting natural antioxidant active substances from the bark of Amla emblica. Background technique Emblica (Phyllantus emblica) has a wide distribution of resources in southern my country. The fruit of Emlica emblica has medicinal functions such as clearing away heat, cooling blood, invigorating digestion, invigorating the stomach, promoting body fluid and relieving cough, and inhibiting bacteria. It can be processed into food, beverages, health products, medicines and cosmetics. In recent years, the development and utilization of emblica resources mainly focus on the artificial cultivation and fruit processing and utilization of emblica. The bark of Amla emblica is rich in plant polyphenols, and its main component is a mixture (3:1) of partially citrusylated (about 25%) polymeric prodelphinidins-polymeric proanthocyan...
