Problems solved by technology

[0004] Yarrow contains various active ingredients such as organic acids and flavonoid glycosides. In related technologies, the extraction of Yarrow is often aimed at the extraction and separation of a single component. The effect plays a certain role, and there is a synergistic effect between the active ingredients, therefore, the extraction method of the yarrow extract needs to be improved

Abstract

The application relates to the technical field of plant extraction, and specifically discloses an extraction method and application of a yarrow extract. A method for extracting yarrow extract, comprising the following steps: pulverizing yarrow, performing enzymatic extraction on yarrow powder; microfiltration, collecting the filtrate to obtain a crude extract of yarrow; The crude grass extract is subjected to ultrafiltration, and the ultrafiltration filtrate is collected; the ultrafiltration filtrate is concentrated and desalted to obtain the yarrow extract; the yarrow extract includes organic acids and flavonoids. The extraction method of the present application extracts a variety of active ingredients from yarrow, and the extraction and separation rate is relatively high, which ensures that the active ingredients of yarrow are not destroyed to the greatest extent, so that the extract of yarrow has a better effect in cosmetics. Brighten skin tone, anti-inflammatory, inhibit pigmentation and other effects.

Description

technical field [0001] The application relates to the technical field of plant extraction, more specifically, it relates to an extraction method and application of a yarrow extract. Background technique [0002] Yarrow (Achillea millefolium L., also known as yarrow), is a perennial herb of the genus Asteraceae, yarrow is acrid, bitter, and cold in nature, and is commonly used as an anti-inflammatory, analgesic and antispasmodic agent. [0003] In recent years, more and more components in yarrow have been discovered. For example, the total organic acids of yarrow have antibacterial, anti-inflammatory, antipyretic and analgesic effects, which have been published in journals. Flavone glycosides can reduce the transport of melanosomes and the growth of dendrites of melanocytes, thereby inhibiting the transport of melanin to keratinocytes, thereby achieving a certain effect of brightening skin tone. Some cosmetic raw material companies also extract the effective parts of yarrow f...
