Embodiment 1

[0023] The instruments and consumables used in this embodiment are: Pulverizer, Electronic Analytical Balance (XA205DU): Sensitivity 0.001g, Accelerated Solvent Extractor Model: ASE-350 (10ml extraction pool, 50ml collection bottle), volumetric bottle: 100ml, Centrifuge tube: 2ml.

[0024] Step 1: Take about 0.25g of wild chrysanthemum powder (passed through a No. 3 sieve), weigh it accurately, mix it with 0.25g of diatomaceous earth, and set aside;

[0025] Step 2: Pad 3 to 6 sheets (1 piece of commercial filter paper) at the bottom of the extraction pool with homemade circular filter paper (diameter 27mm), add about 1g of diatomaceous earth, then add the homogeneously mixed sample obtained in step 1, and then add an appropriate amount of diatomaceous earth , shake gently to make it at the same level as the pool mouth, and tighten the upper cover of the extraction pool.

[0026] Step 3: ASE extraction, the extraction parameters are as shown in Table 1

[0027] Table 1 ASE e...

Abstract

The invention discloses a method for extracting linarin from wild chrysanthemum flower, which comprises the following steps: 1. pulverizing wild chrysanthemum flower, passing through a 50-mesh screen, and mixing with diatomite; 2. extracting linarin by ASE (accelerated solvent extraction), and collecting the extracting solution, wherein the extraction solvent adopted by the ASE is methanol; and 3. carrying out centrifugal separation on the extracting solution to obtain the linarin-containing supernate. The method has the advantages of high extraction speed and high precision.

Description

technical field [0001] The invention relates to the technical field of chemical detection, in particular to a method for extracting mongoside from wild chrysanthemum. Background technique [0002] This product is the dry flower head of Chrysanthemumindicum L. It is picked when the flowers first open in autumn and winter, dried in the sun, or steamed and then dried in the sun. This product is spherical in shape, 0.3-1cm in diameter, brownish yellow. Involucre is composed of 4-5 layers of bracts, the outer bracts are ovate or strip-shaped, the middle part of the outer surface is gray-green or light brown, usually covered with white hairs, and the edges are membranous; the inner bracts are oblong, membranous, The outer surface is hairless. Remnant total pedicel present at base of involucre. Tongue-shaped flowers in 1 round, yellow to brown-yellow, shrunken and curled; numerous tubular flowers, dark yellow. Lightweight. Gas aroma, bitter taste. The extraction method recor...
