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 invention relates to the technical field of plant extraction, and particularly discloses an extraction method and application of an achillea millefolium extract. The extraction method of the achillea millefolium extract comprises the following steps: crushing achillea millea, and carrying out enzymolysis extraction on achillea millea powder; carrying out microfiltration, and collecting the filtrate to obtain a crude extract of the achillea millefolium; performing ultrafiltration on the crude extract of the achillea millefolium, and collecting ultrafiltration filtrate; and concentrating anddesalting the ultrafiltration filtrate to obtain the achillea millefolium extract. The achillea millefolium extract comprises an organic acid and flavone. According to the extraction method, multipleeffective components are extracted from the achillea millefolium, wherein the extraction separation rate is high; the effective components of the achillea millefolium are not damaged to the maximum extent, and the achillea millefolium extract has the good effects of brightening the skin color, resisting inflammation, inhibiting pigmentation and the like when applied to cosmetics.

Description

technical field [0001] The application relates to the technical field of plant extraction, more specifically, it relates to a method for extracting yarrow extract and its application. Background technique [0002] Achillea millefolium L. (Achillea millefolium L., also known as yarrow), is a perennial herb of the genus Yarrow in the family Asteraceae. Achillea millefolium is pungent, bitter, and cold in nature, and it is often used as an anti-inflammatory, analgesic, and antispasmodic agent among the people. [0003] In recent years, more and more ingredients 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. Flavonoid glycosides can reduce the transfer of melanosomes and the growth of melanocyte dendrites, thereby inhibiting the transfer of melanin to keratinocytes, so as to achieve a certain effect of brightening the skin tone. Some co...
