Embodiment 1

[0026] Cut 100.0g Aloe vera into slices of about 5mm, and dry it in vacuum at 30°C for 6 hours to obtain dried aloe, and then add 7g Na 2 CO 3 As an alkali aid, add balls at a filling rate of 10%, perform mechanical ball milling pretreatment at a speed of 500r / min for 30 minutes, and obtain dry aloe powder, then add a volume fraction of 10 at a material-to-liquid ratio of 1:15 % ethanol aqueous solution was used as the extraction solvent, ultrasonically extracted for 40 minutes at a temperature of 40°C, and 75% ethanol was added for precipitation to obtain 0.524 g of aloe polysaccharides, and the extraction rate of polysaccharides was 0.524%.

Embodiment 2

[0028] Cut 100.0g Aloe vera into thin slices of about 5mm, and dry it under vacuum for 8h at a temperature of 35°C to obtain dried aloe, and then add 8g Na 2 CO 3 As an alkali aid, add grinding balls at a filling rate of 15%, perform mechanical ball milling pretreatment at a speed of 400r / min for 25 minutes, and obtain dry aloe vera powder, then add 20% ethanol aqueous solution at a material-to-liquid ratio of 1:20 For the extraction solvent, ultrasonic extraction was performed at 45°C for 35 minutes, and 80% ethanol was added for precipitation to obtain 0.589 g of aloe polysaccharides, and the extraction rate of polysaccharides was 0.589%.

Embodiment 3

[0030] Cut 100.0g Aloe Vera into slices of about 5mm, and dry it under vacuum at 40°C for 10h to obtain dried Aloe Vera, then add 9g Na 2 CO 3 As an alkaline aid, add balls at a filling rate of 20%, perform mechanical ball milling pretreatment at a speed of 500r / min for 20 minutes, and obtain dry aloe vera powder, then add 25% ethanol aqueous solution at a material-to-liquid ratio of 1:25 For the extraction solvent, ultrasonic extraction was performed at 60°C for 40 minutes, and 90% ethanol was added for precipitation to obtain 0.612 g of aloe polysaccharides, and the extraction rate of polysaccharides was 0.612%.

Abstract

The invention provides a method for quickly separating aloe polysaccharide from the aloe. The method comprises the following steps that plant raw materials containing the aloe polysaccharide are cut into thin slices, and are dried for 1-24 h at 20-60 DEG C to obtain dried aloe; then after an appropriate amount of an alkali aid is added, a grinding ball with a grinding ball filling rate of 5-50% isadded, mechanical ball grinding pretreatment is conducted for 5-60 min to obtain dried aloe powder, then an extraction solvent is added at the feed liquid ratio of 1:5 to 1:50, ultrasonic extractionis conducted for 5-60 min at 20-80 DEG C, 70-99% of ethanol is added for precipitation to obtain the aloe polysaccharide, wherein the alkali aid is NaOH, Na2CO3 or NaCO3; and the plant raw materials containing the aloe polysaccharide comprise aloe plants of liliaceae.

Description

technical field [0001] The invention belongs to a method for separating aloe curdlan from aloe. Background technique [0002] Aloe vera tastes bitter and cold, and has anti-inflammatory and antibacterial effects. It is often used to treat headaches, liver heat, constipation, gallstones, and tinea eczema. Directly getting its original plant as medicine is unfavorable for clinical application. Aloe vera gellan is one of the main biologically active components of aloe vera. The polysaccharides of aloe vera mainly exist in the gel part of aloe vera leaves, that is, the transparent mucus-like part surrounded by aloe vera leaf skin. Studies have found that aloe gelatin has strong physiological activity on the human body, and has various effects such as broad-spectrum immune regulation, anti-radiation, anti-tumor, anti-ulcer, anti-AIDS virus, skin care and beauty. [0003] At present, aloe polysaccharides are generally extracted from fresh aloe with water or ethanol solutions of ...
