Problems solved by technology

Collagen fibers in the dermis endow the skin with tension and toughness, and its uneven distribution or structural changes cause light to not be reflected evenly, making the skin color uneven and dull; in addition, if the vascular filling in the dermis is insufficient or blood circulation is not smooth, Then hemoglobin aggregation or pigment content will decrease, resulting in dark red or pale skin

preparation example Construction

[0027] The invention discloses a preparation method of mate tea extract. The specific extraction process includes: extraction, decoction, reflux extraction, ultrasonic extraction, microwave extraction, dynamic extraction, etc.

[0028] In some embodiments, the yerba mate raw material may be pre-treated prior to extraction. For example, pretreatment methods may include crushing, degreasing, and the like.

[0029] Generally speaking, the extraction process of yerba mate is as follows: after pretreatment (if any) of yerba mate (for example, yerba mate from Fujian Yatong Lvyuan Tea Co., Ltd.), add an appropriate amount of solvent for extraction, Removing the slag and taking the extract, concentrating it to make a yerba mate tea concentrate with a certain crude drug concentration.

[0030] In some specific embodiments, a solvent extraction method is used to prepare the yerba mate tea extract. For example, the solvents that can be used include hydrophilic solvents such as deioniz...

specific Embodiment approach

[0057]The inventors of the present invention unexpectedly found that the extract of yerba mate tea can effectively inhibit the activity of tyrosinase, thereby effectively inhibiting the increase of melanin and playing the roles of whitening the skin or lightening freckles; the extract of yerba mate tea can also Effectively inhibit the activity of hyaluronidase, so as to maintain the content and normal function of hyaluronic acid in cells or tissues, maintain the elasticity and normal function of epidermal cells, and play a moisturizing and anti-allergic effect on the skin; yerba mate tea extract can Significantly inhibit the massive release of NO by macrophages after LPS stimulation, thereby inhibiting or alleviating the occurrence of inflammatory response and playing an anti-inflammatory role.

[0058] The present invention is further described below in conjunction with specific examples. However, it should be understood that these examples are only used to illustrate the pre...

Abstract

The invention discloses a preparation method of a yerba mate tea extractive. The preparation method is selected from decoction extraction, solvent extraction and ultrasonic extraction. The invention also discloses application of the yerba mate tea extractive extracted with the preparation method to skin whitening, skin antianaphylaxis and skin inflammation resistance.

Description

technical field [0001] The invention belongs to the field of phytochemistry, and in particular relates to a preparation process of a yerba mate tea extract and its application in skin external preparations or cosmetics. Background technique [0002] The skin refers to the tissue on the surface of the body that covers the muscles. It is the largest organ of the human body and mainly undertakes functions such as protecting the body, perspiration, and feeling cold, heat, and pressure. The skin covers the whole body, protecting various tissues and organs in the human body from external substances such as pathogenic microorganisms and physical and other mechanical damage, effectively resisting external stimuli; the skin also maintains the loss of water, electrolytes and nutrients in the human body, effectively It maintains the stability of the internal environment of the human body and is a natural barrier to protect the human body. [0003] The skin is composed of three parts: ...
