Problems solved by technology

But at present, the economic value of the sandy date tree has not attracted much attention. Only a small part of the sandy date has been processed and utilized among the people, and most of them have not been collected, and the utilization is very low, which has caused a lot of waste. The average polysaccharide content is between 9% and 10.9%, and the total polysaccharide content is relatively high. The sugar part mainly contains rhamnose, arabinose, xylose, glucose, mannose, and galactose. The activity has the functions of

Abstract

The invention relates to an Elaeagnus angustifolia polysaccharide extract capable of relieving dry skin inflammation and a preparation method thereof. The Elaeagnus angustifolia polysaccharide of theinvention is prepared from Elaeagnus angustifolia gum through a water extraction and alcohol precipitation process. Researches show that the extract containing Elaeagnus angustifolia polysaccharide has the effect of relieving dry skin inflammation. The Elaeagnus angustifolia polysaccharide extract can be made into various dosage forms such as gel, a liquid, an emulsion, an ointment, solid particles, etc., and is applied to the fields of cosmetic and dermatosis accessory therapeutic medicines and the like.

Description

technical field [0001] The present invention relates to a polysaccharide extract of Elaeagnus japonicus with anti-inflammatory and moisturizing effects. The extract can effectively promote the expression of moisturizing factors Filaggrin FLG and loricrin LOR while inhibiting the skin inflammatory factor IL-6 And the expression of TNFα, it can be added to cosmetics as functional active substances for skin care. Background technique [0002] Skin covers the surface of the whole body and is one of the largest organs of the human body. It is the tissue directly in contact with the external environment and is the body's natural skin barrier, skin barrier and physical barrier. Composed of polysaccharides, etc., it resists external harmful substances, irritants, and sunlight, and at the same time has moisturizing and regulating anti-inflammatory effects. [0003] The natural moisturizing system in human skin is mainly composed of water, lipids, natural moisturizing factor (Natural...
