preparation example Construction

[0023] The embodiment of the present application shows a preparation method of artichoke extract, comprising the following steps:

[0024] S1 steaming: steaming the dried artichoke raw material at 100-120°C for 4-8 hours;

[0025] S2 pre-treatment: dry the steamed artichoke raw material, and then chop it with a medicine cutter to obtain the clean material;

[0026] S3 extraction: Weigh the net material and put it into the reaction kettle, heat the water to reflux for extraction, and collect the extract after filtering;

[0027] S4 Concentration, alcohol precipitation: Concentrate the collected extract, add ethanol solution for alcohol precipitation, filter and collect the settled supernatant;

[0028] S5 adsorption and elution: the collected filtrate is adsorbed by a resin column, and eluted by an ethanol aqueous solution through an adsorption column, and the alcohol washing solution is filtered and collected;

[0029] S6 Concentration and spray drying: The collected alcohol...

Embodiment 1

[0038] Steam the artichoke raw material dried in the shade at 120°C for 4 hours; dry the artichoke raw material after steaming, and then chop it with a medicine cutter to obtain a 40-mesh clean material; weigh 500g of the clean material and put it into the reaction kettle, and then Add 4 times of hot water, heat to 90°C and turn on heat reflux. After extraction for 3 times, add 2 to 3 times of water for the last two times, filter out impurities through a 0.45 μm filter membrane, and collect the extract. Concentrate the extract to a liquid-to-solid ratio of 1:2, add ethanol solution to prepare a solution with an ethanol concentration of 50%, and carry out alcohol precipitation after cooling for 24 hours, and pass the settled supernatant through a 0.45 μm filter membrane Impurities were filtered off, and the filtrate was collected. The filtrate is adsorbed by a polyamide resin column, and ethanol aqueous solutions with a concentration of 15%, 45%, and 95% are respectively eluted...

Embodiment 2

[0041] Steam the artichoke raw material dried in the shade at 120°C for 6 hours; dry the artichoke raw material after steaming, and then chop it with a medicine cutter to obtain a 50-mesh clean material; weigh 500g of the clean material and put it into the reaction kettle, and then Add 4 times of hot water, heat to 95°C and turn on heat reflux. After extraction for 3 times, add 2 to 3 times of water for the last two times, filter out impurities through a 0.45 μm filter membrane, and collect the extract. Concentrate the extract to a liquid-to-material ratio of 1:1, add ethanol solution, and configure a solution with an ethanol concentration of 50%, and carry out alcohol precipitation after cooling for 24 hours, and pass the settled supernatant through a 0.45 μm filter membrane Impurities were filtered off, and the filtrate was collected. The filtrate is adsorbed by a polyamide resin column, and ethanol aqueous solutions with a concentration of 15%, 45%, and 95% are respectively...

Abstract

The embodiment of the invention discloses a preparation method of a globe artichoke extract. The preparation method comprises the following steps: steaming, namely steaming a dried globe artichoke rawmaterial at 100-120 DEG C for 4-8 hours, wherein the globe artichoke raw material is dried in the shade before steaming; carrying out pretreatment, namely airing the steamed globe artichoke raw material, slicing by virtue of a medicine slicing machine, so as to obtain a net material; carrying out extraction, namely weighing the net material, putting the net material into a reaction kettle, addinggot water, carrying out reflux extraction, filtering extracting liquid, and collecting; carrying out concentration and alcohol precipitation, namely concentrating the collected extracting liquid, adding an ethanol solution for alcohol precipitation, filtering settled supernatant, and then collecting; adsorbing and eluting, namely adsorbing the collected filtrate through a resin column, eluting byethanol water solution through an adsorption column, filtering ethanol-washed liquid, and then collecting; and carrying out concentration and spray drying, namely carrying out vacuum concentration onthe collected ethanol-washed liquid so as to obtain thick slurry, and carrying out spray drying and sieving, so as to obtain the globe artichoke extract. The globe artichoke extract prepared by virtue of the method is capable of increasing the content of a caffeic acid derivative in the extract and is suitable for industrial production.

Description

technical field [0001] The present application relates to the technical field of natural plant extraction, in particular to a preparation method of artichoke extract. Background technique [0002] Artichoke (Cynarascolymus L.), also known as French lily, lotus lily, artichoke, "artichoke" and "ball thistle", is a perennial herb of the Asteraceae family, native to the Mediterranean coast. France introduced into our country. It is cultivated more in Spain, France, Italy and California, USA. Domestically, artichokes are mainly cultivated in Shanghai, Beijing, Zhejiang, Hunan, Yunnan and other places. The edible part of the artichoke is the fat and tender bracts of the receptacle and the fleshy flower buds, which are rich in nutrients, such as calcium, phosphorus, iron, iodine, potassium and other minerals, as well as vitamins A, B, and C. At the same time, the plant is rich in active substances such as cymarin, polyphenols (including chlorogenic acid), inulin (in the tuber r...
