Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the extraction efficiency is not high, or the temperature is too high for a long time, or the removal of potentially skin-irritating anthraquinones is not considered during the many known extraction methods of aloe polysaccharides, or In order to solve the problems of high cost, a method for extracting aloe polysaccharides is provided. Specifically, the microwave-ultrasonic combined assisted extraction method is used to remove the anthraquinone components in the aloe leaves, and the process of alcohol precipitation is carried out at the same time, and then the whole aloe is extracted by the ultrasonic assisted extraction method. Method for active polysaccharides in leaves, and optimized extraction process

Embodiment 1

[0062] This embodiment relates to a method for removing impurities and extracting polysaccharide components in fresh leaves of aloe vera based on microwave and ultrasonic-assisted extraction, which specifically includes the following steps:

[0063] Step 1: Raw material pretreatment

[0064] Fresh and disease-free whole leaves of Aloe vera were taken, washed, cut into blocks, and the tissues were broken to obtain whole leaf juice of aloe vera, which was refrigerated at -10°C for later use.

[0065] Step 2: Removal of anthraquinone components

[0066] Weigh the whole leaf juice of aloe vera according to the volume ratio of 1:9, put it in a beaker, add 9 times the volume of absolute ethanol, heat it to 77°C with microwave (700w), cool it, and put it in ultrasonic (frequency 40KHz; power 100W ) in the extractor for 30 minutes, allowed to stand for 1 hour, filtered, and the filter residue was set aside.

Abstract

The invention discloses an aloe polysaccharide extracting method and an aloe skin moistening composition. Full aloe leaf juice is weighed out, added with absolute ethyl alcohol and subjected to microwave treatment until the temperature of the mixed liquid reaches 75-77 DEG C, the mixed liquid is cooled, ultrasonic waves are used for assisting in extracting anthraquinones in the mixed liquid continually, extraction and filtering are carried out, and an anthraquinone ingredient extract solution and filter residues are obtained; deionized water is added to the filter residues according to the material and liquid ratio of 1:20-40, extraction is carried out for 20-60 minutes with the ultrasonic waves power ranging from 400 W to 800 W, filtering is carried out, and an aloe polysaccharide extract solution is obtained. According to the extracting process, aiming at the polysaccharide ingredients in full aloe leaves, the extracting time is effectively shortened under the premise that the extraction rate is ensured, and the aloe polysaccharide extract solution has the good moistening property and has certain antioxidant activity; in addition, the anthraquinone matter with potential skin irritation is effectively removed, an aloe skin moistening formulation adopting the aloe polysaccharide extract solution achieves good moistening, itching relieving and antioxidant activity effects.

Description

technical field [0001] The invention relates to plant extraction and application, in particular to an aloe polysaccharide extraction method and an aloe moisturizing composition. Background technique [0002] Aloe is a perennial evergreen succulent herb belonging to the Liliaceae Aloe family, with more than 500 varieties. Edible varieties are mainly Aloe vera. The main active ingredients of aloe are polysaccharides, and their molecular structure, composition and relative molecular weight are related to the variety, growth environment and growth period of aloe. Aloe vera polysaccharide is a mannan with branched chains, with mannose as the branched chain connection point, wherein the content ratio of glucose and mannose is 1:22 (Deng Yangyong, Wu Shenrong, etc., the influence of aloe polysaccharides on the immune organs of aging mice , Journal of Hunan University of Traditional Chinese Medicine, 2008.28(2):25-27). Aloe polysaccharides have various bioactive functions such as...
