preparation example Construction

[0044] The first embodiment of the present invention provides a method for preparing a novel filler, which specifically includes the following steps:

[0045] 1. Prepare monomer: put 120-130kg styrene (cross-linking monomer), 9-10kg methyl acrylate (monomer) and 1-1.5kg dibenzoyl peroxide (catalyst) into No. 1 reactor, Mix and stir at room temperature for 25 to 30 minutes, then add 170 to 180 kg of methylcyclohexane (porogen), and stir at room temperature for 25 to 30 minutes to obtain monomers;

[0046] 2. Preparation of water phase: Put appropriate amount of water in No. 2 reactor, then put in powdered salt, stir to make the brine uniform, the specific gravity of the brine is 1.12-1.2, put 7-9kg of gelatin and 0.01- 0.03kg of methylene blue, stir and heat to 55-60°C, stop stirring and keep warm to obtain the water phase;

[0047] 3. Pump the prepared monomer from the No. 1 reactor into the No. 2 reactor, and directly start stirring for 10-15 minutes without heating up to ob...

Embodiment 1

[0075] 1. Put 120kg of styrene, 9kg of methyl acrylate and 1kg of dibenzoyl peroxide into the No. 1 reactor, mix and stir at room temperature for 30 minutes, then add 170kg of methylcyclohexane, and stir at room temperature for 25 minutes to obtain the monomer;

[0076] 2. Put brine with a specific gravity of 1.12, 9kg of gelatin and 0.01kg of methylene blue into the No. 2 reactor, stir and heat to 55°C, stop stirring and keep warm to obtain the water phase;

[0077] 3. Pump the monomer from the No. 1 reactor into the No. 2 reactor, and directly start stirring for 10 minutes without heating up to obtain the mixed material. Slowly raise the temperature of the mixed material in the No. 2 reactor to 68 ° C and keep it warm for 4 hours Finally, the steam heating slowly raises the temperature to 70°C, and keeps the temperature for 6 hours. The stirring cannot be stopped during the whole process. The mixed material is gradually formed into a new type of spherical particle filler duri...

Embodiment 2

[0096] 1. Put 125kg styrene, 9.5kg methyl acrylate and 1.2kg dibenzoyl peroxide into No. 1 reactor, mix and stir at room temperature for 28min, then drop into 172kg methylcyclohexane, stir at room temperature for 26min to obtain a single body;

[0097] 2. Put brine with a specific gravity of 1.15, 8.5kg of gelatin and 0.02kg of methylene blue into the No. 2 reactor, stir and heat to 60°C, stop stirring and keep warm to obtain the water phase;

[0098] 3. Pump the monomer from the No. 1 reactor into the No. 2 reactor, and directly start stirring for 10 minutes without heating up to obtain the mixed material. Slowly raise the temperature of the mixed material in the No. 2 reactor to 70°C and keep it warm for 5 hours Finally, the steam heating slowly raises the temperature to 75°C, and keeps the temperature for 6.5 hours. The stirring cannot be stopped during the whole process. The mixed material is gradually formed into a new type of spherical particle filler during the above-me...

Abstract

The invention belongs to the technical field of bioengineering, and provides a preparation method for preparing saffron standard product from Gardenia jasminoides by using a new type of filler. In the dynamic axial compression column of the novel filler, the novel filler is used as the stationary phase, and the organic solvent is used as the mobile phase, and analytical separation is carried out in the dynamic axial compression column to obtain a saffron solution, and the saffron solution is concentrated to remove the organic solvent, Then the remaining solution was dried to obtain the standard saffron. The present invention separates and purifies the crude saffron through a dynamic axial compression column equipped with a new type of filler, adopts the new type of filler as the stationary phase, and uses ethanol, ethyl acetate, and n-butanol as the mobile phase, which can speed up the separation speed and improve the production efficiency , reduce the usage of mobile phase solvent, save cost and have excellent separation and purification effect, and obtain saffron standard product with a purity as high as 98.5%.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a novel filler and a preparation method thereof, and a method for extracting crocin from gardenia jasmine based on the novel material extraction. Background technique [0002] Gardenia jasminoides Ellis (Gardenia jasminoides Ellis), also known as yellow gardenia, mountain gardenia and white toad, is the fruit of Rubiaceae gardenia, mainly distributed in Zhejiang, Jiangxi, Hunan, Fujian and other places. It has extensive resources and belongs to the first batch issued by the Ministry of Health. Food and medicine resources. It has been recorded in "Compendium of Materia Medica" that gardenia enters the heart, liver, lungs, and stomach meridians, can clear away heat, purify fire, cool blood, and has the functions of protecting the liver, promoting gallbladder, lowering blood pressure, calming, stopping bleeding, and reducing swelling. It mainly contains Various active ingred...
