Abstract

The invention discloses a method for extraction of magnolin in magnolia flower by an ASE(accelerated solvent extraction) method, belongs to the field of extraction of the magnolin, and aims to providea method with short extraction time and good repeatability for extraction of the magnolin in the magnolia flower. The method is as follows: crushing a magnolia flower sample, mixing 1g of the magnolia flower sample and 1g of diatomaceous earth evenly, placing the mixture in an ASE extraction cell with a filter membrane and 3g of neutral alumina, adding the diatomaceous earth to be parallel to theopening of the cell; and extracting with ethanol, at the end of the extraction, diluting with the ethanol to 50 ml, shaking well and filtering to obtain filtrate. The method can replace a pharmacopoeia method for extraction of the magnolin in the magnolia flower.

Description

technical field [0001] The invention belongs to the extraction field of magnolia, in particular to an ASE method for extracting magnolia from magnolia. Background technique [0002] The method for extracting Magnolin from Magnolia Magnolia recorded in the 2015 edition of the Pharmacopoeia method is as follows: take about 1g of the coarse powder of this product, accurately weigh it, put it in a conical flask with a stopper, add 20ml of ethyl acetate accurately, and weigh it. Soak for 30 minutes, sonicate (power 250W, frequency 33kHz) for 30 minutes, let cool, weigh again, make up the lost weight with ethanol, shake well, filter, accurately measure 3ml of filtrate, add to neutral oxidation On an aluminum column (100-200 mesh, 2g, inner diameter 9mm, wet-packed, pre-washed with 5ml ethyl acetate), elute with 15ml ethanol, collect the eluate, put it in a 25ml measuring bottle, add ethanol to the mark , Shake well, filter, take the continued filtrate, that is. [0003] This met...
