Embodiment 1

[0025] Embodiment 1: A method for enriching and purifying the total flavonoids of Phellinus Phellinus using the coupling method of batch distillation-macroporous adsorption resin, the steps are as follows:

[0026] (1) After crushing the dried Phellinus Phellinus, through a 60-mesh sieve, reflux extraction with ethanol with 5 times the volume of Phellinus Phellinus powder, 1.5 hours each time;

[0027] (2) suction-filtering the Phellinus Phellinus extract treated through step (1), and recovering ethanol from the filtrate under reduced pressure to obtain the primary extract;

[0028] (3) The pH value of the obtained primary extract was adjusted to 2.0 with acid, left to stand, suction filtered, and washed with water until neutral, and concentrated under reduced pressure to obtain the crude extract of total flavonoids of Phellinus japonica;

Abstract

The invention belongs to the field of natural organic chemistry and relates to a method for enriching and purifying common phellinus fungus general flavone in common phellinus fungus by using a batch distillation-macroporous absorption resin coupling method. The method is characterized in that the common phellinus fungus general flavone is separated and purified by applying a macropore adsorption technology, the adsorption selectivity to the common phellinus fungus general flavone is better, the separation effect is remarkable, the extraction purity is high, the semi-finished product with more than 35 percent of the common phellinus fungus general flavone and the final product with above 90 percent of the common phellinus fungus general flavone can be obtained, and the defects of relatively lower conventional extraction rate and low extraction purity are overcome. Macroporous absorption resin with stable physicochemical property, large surface area, higher switching speed, high mechanical strength, strong contamination resistance and good thermal stability is selected, and the common phellinus fungus general flavone is selectively absorbed from a solution through physical adsorption, thus the method has the advantages of high adsorption, high deabsorption speed and larger adsorption capacity.

Description

Technical field: [0001] The invention belongs to the field of natural organic chemistry, and relates to a method for purifying total flavonoids of Phellinus phellidis, in particular to a method for enriching and purifying total flavonoids of Phellinus phellidis using a coupling method of intermittent distillation and macroporous adsorption resin. Background technique: [0002] Phellinus, derived from the fruiting body of the fungus Basidiomycetes Polyporaceae Polyporaceae Phellinus igniarius (L.ex Fr) Quel. Also known as: Phellinus igniarius (L.ex Fr) Quel Acupunculus. Born on the trunks of broad-leaved trees such as poplar, willow, birch, oak, rhododendron, and Sizhaohua, causing white rot in the heartwood, perennial; beneficial to the five internal organs, soft and hard, detoxification, hemostasis, blood circulation, and stomach and diarrhea. Cure mainly gonorrhea, uterine bleeding, leukorrhagia, accumulation of lumps in the abdomen, addiction to drinking, diarrhea due to...
