Embodiment 1

[0023] Embodiment 1, the preparation method of Eucommia ulmoides leaf extract microcapsules in the present embodiment, comprises the following steps

[0024] ① pulverizing, pulverizing the dried eucommia leaves to obtain a dry powder with a particle size of 80-100 mesh;

[0025] ②Solvent extraction is used, the conditions are as follows: water and ethanol mixed solvent is used as the extractant, the weight ratio of the extractant is 3 times that of Eucommia dry powder, the temperature is 70°C, the extraction is 1 hour, the pH is 5, and the extraction is 3 times, the water in the extractant and The volume ratio of ethanol is 40%:60%, and then evaporated and concentrated to 10% of the original volume. The solvent extraction process is simple, low in cost and less in investment.

[0026] ③Microencapsulation, the weight ratio of core material and wall material is 0.5:1, the wall material is composed of gum arabic and β dextrin, and the weight ratio of acacia gum and β dextrin is 1...

Embodiment 2

[0030] Embodiment 2, the preparation method of Eucommia ulmoides leaf extract microcapsules in the present embodiment, comprises the following steps

[0031] ① pulverizing, pulverizing the dried eucommia leaves to obtain a dry powder with a particle size of 80-100 mesh;

[0032] ②Ultrasonic extraction, the conditions are as follows: the mixture of ethanol and water is used as the extractant, the dry powder: extractant weight ratio is 1:8, pH4, the extraction time is 15 to 30 minutes, the volume ratio of ethanol in the extractant is 55%, the extraction 3 times, using the cavitation effect of ultrasonic waves to destroy the cell wall and quickly dissolve the active ingredients.

[0033] ③Microencapsulation, the weight ratio of the core material to the wall material is 0.3-0.7, the wall material is composed of gum arabic and β dextrin, and the weight ratio of acacia and β dextrin is 1:1, the wall material is prepared as follows: Dissolve gum arabic and β-dextrin separately at a ...

Embodiment 3

[0037] Embodiment 3, the preparation method of Eucommia ulmoides leaf extract microcapsules in the present embodiment, comprises the following steps

[0038] ① pulverizing, pulverizing the dried eucommia leaves to obtain a dry powder with a particle size of 80-100 mesh;

[0039] ②Using microwave extraction, the conditions are as follows: use the mixture of ethanol and water as the extractant, the weight ratio of dry powder:extraction solvent is 1:12; the pH value is 4; microwave 500w; the extraction time is 3 to 5 minutes, The volume ratio is 50-60%, and the extraction is performed three times. The internal heating effect of the microwave on the extraction solvent and the material is used, so that many insoluble substances are better dissolved under the action of the microwave electromagnetic field.

[0040] ③ Microencapsulation, the weight ratio of core material and wall material is 0.7:1, the wall material is composed of gum arabic and β dextrin, and the weight ratio of acac...

Abstract

The invention relates to a method for preparing folium cortex eucommiae extract microcapsules. The method is characterized by comprising the following steps of: (1) pulverizing: pulverizing dried folium cortex eucommiae to obtain dry powder of which the particle size is 80-100 meshes; (2) extracting; (3) microcapsule preparation, wherein the weight ratio of core material to wall material is 0.3-0.7:1, the wall material is prepared from arabic gum and beta-dextrin, and the weight ratio of arabic gum to beta-dextrin is 1-2:1; and (4) and spray-drying. Compared with the prior art, the method has the advantages that the obtained product has strong oxidation resistance, high stability, instant dissolution and stable curative effect, and the whole process is easy to operate and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a method for preparing microcapsules, in particular to a method for preparing microcapsules from eucommia leaf extract. Background technique [0002] Eucommia ulmoides oliv is a valuable medicinal plant in my country. The famous ancient medical books "Shen Nong's Materia Medica", "Compendium of Materia Medica" and the current authoritative medical book "Chinese Medicine Dictionary" have detailed descriptions, saying that it can benefit the liver and kidney, take it lightly and resist aging, and can cure waist and knee weakness , impotence due to deficiency of the kidney. Further research on Eucommia by modern medicine shows that Eucommia is rich in more than 40 active ingredients such as chlorogenic acid and flavonoids, and has 16 comprehensive functions such as promoting metabolism, enhancing immunity, delaying aging, regulating blood pressure, and inhibiting tumors, especially cleaning human blood vessels. , treatment of hi...
