Problems solved by technology

Since the impurity removal method described in this patent cannot effectively remove plant-based mucilages such as tannins, colloids, and proteins with relatively large molecular weights in the extract, a large amount of precipitation occurs in the extract during the shelf life, which greatly affects the stability of the product. influences

Abstract

The invention discloses a preparation method and an application for an aloe flower extracting solution. The preparation method comprises the following steps: preparation of a crude extracting solution, pretreatment, removal of sediment through a micro-filtration membrane, separation through an ultra-filtration membrane, and concentration through a nano-filtration membrane. The method is convenientto operate, low in energy consumption, low in cost, ecological, environmentally friendly and applicable to industrial production; the active substance, namely polyphenol, in the aloe flower is reserved in an obtained aloe flower extracting solution to the maximum extent, and interference of macromolecular impurities like plant pituitous substances is effectively removed, so the quality stabilityof the aloe flower extracting solution is reinforced. 3D skin model test results show that the aloe flower extracting solution can significantly improve the tissue activity of a model, has an obviousimprovement effect on the phenomena of reduction of the number of living cells, loose arrangement and the like, and significantly reduces the IL-1 alpha secretion level; and the apparent chromaticityof the model is obviously improved, and the L * value is obviously increased, while the melanin content is reduced. The aloe flower extracting solution prepared by using the preparation method provided by the invention does not contain any toxic solvent, is stable in quality and definite in effect, and can be applied to cosmetics for resisting aging, resisting allergy, whitening and the like.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a preparation method and application of an aloe flower extract. Background technique [0002] Aloe vera is an ancient medicinal plant. According to the unearthed Assyrian clay tablets, as early as 1750 BC, people in Mesopotamia recognized the therapeutic effect of aloe vera. The ancient Chinese medical book "Puji Fang" , "Compendium of Materia Medica" also records the special medicinal effect of aloe. There are more than 500 kinds of aloe in the world, and more than 50 kinds of aloe with development value have been found at present, among which aloe vera is one of the most mature varieties for industrial development. Modern pharmacological experiments have proved that the effective parts or active ingredients in the aloe plant have various functions such as antibacterial, anti-inflammatory, antipyretic, liver protection, anti-cancer, insecticidal and immune enhancement, and are know...
