Abstract

The invention provides a pitaya stem extract, a preparation method and applications thereof. The preparation method comprises: (a) cleaning pitaya stem, removing spines, cutting into sections, crushing with a colloid mill, adding deionized water, adding diluted pectinase, and carrying out stirring extraction; (b) carrying out enzyme inactivation, cooling, carrying out coarse filtration, and carrying out fine filtration; and (c) decolorizing, cooling, filtering, and carrying out sterilizing preserve on the filtrate to obtain the pitaya stem extract. Compared to the preparation method in the prior art, the preparation method of the present invention has the following advantages that the extraction separation operation is simple, the extraction rate of the active component is high, and the purity of the finally prepared product is high. According to the present invention, the pitaya stem extract has effects of inflammation eliminating, antibacterial effect, skin moisturizing, wound healing promoting, capillary circulation enhancing and the like; and the test results show that the extract prepared through the method of the present invention can be used as the moisturizing anti-allergicagent, and can be widely used in the preparation of cosmetics, especially in the preparation of cosmetics with moisturizing and anti-allergic effects.

Description

technical field [0001] The invention relates to a plant extract, in particular to a dragon fruit stem extract. Simultaneously, the present invention also relates to a preparation method of the pitaya stem extract and its application in cosmetics. Background technique [0002] Allergies, also known as allergic reactions, are immune responses produced by people with allergic constitutions who come into contact with allergens. Skin allergy is one of the common skin problems, and in recent years, with changes in diet, air pollution, life and work pressure, the number of allergic patients has increased dramatically.
