Description

Technical Field

[0001] This invention relates to a plant extract composition and its application, particularly to an extract composition of loquat flower and white bud Qilan tea and its application. Background Technology

[0002] With the advancement of the times, people's demands for themselves are increasing, and cosmetics have become a mass-market product. Modern cosmetic ingredients mainly focus on anti-oxidation and anti-inflammation, and how to solve these problems is of great practical significance. Current research on various related products has found that as consumers pay more attention to the ingredients of cosmetics, hair care products, and weight loss products, natural ingredients with significant efficacy are more favored than synthetic compound ingredients.

[0003] As people's understanding of loquat flowers deepens, they have discovered that loquat flowers not only have antibacterial, antioxidant, and anti-inflammatory effects, but also have therapeutic effects on pharyngitis. Patent publication number (CN101366844A) discloses that loquat flowers and their extracts have antitussive and antibacterial effects. Patent publication number (CN1977907B) discloses that loquat flowers and their extracts have antitussive and antibacterial effects. Patent publication number (CN113662891A) discloses the application of loquat flower extract in anti-aging cosmetics.

[0004] In conclusion, loquat flowers have many benefits, but the question of how to better utilize their anti-inflammatory and antioxidant effects has not been solved, and the full potential of loquat flowers' functions and uses has not been explored. Summary of the Invention

[0005] To address the above problems, the present invention aims to provide a plant extract composition and its application, enabling loquat flowers to better exert their anti-inflammatory and antioxidant effects, and providing new uses for loquat flower extract.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention proposes a plant extract composition, comprising, by weight, 20-40 parts loquat flower extract and 60-80 parts white bud Qilan tea extract.

[0008] Furthermore, the preparation steps of the plant extract composition include:

[0009] Loquat flowers were chopped and made into a paste. The paste was then extracted with ethanol, filtered, and the ethanol extracts were combined, concentrated, and dried to obtain loquat flower extract.

[0010] The white bud Qilan tea was chopped and made into a paste. It was then extracted with ethanol, filtered, and the ethanol extracts were combined, concentrated, and dried to obtain the white bud Qilan tea extract.

[0011] A plant extract composition was obtained by mixing loquat flower extract and white bud Qilan tea extract.

[0012] Furthermore, the loquat flower and the white bud Qilan tea extracts are both extracted three times using ethanol.

[0013] Furthermore, the loquat flower is 300 parts, the white bud Qilan tea is 300 parts, and the ethanol used for each ethanol extraction is 400 parts, wherein the ethanol is a 30% to 70% aqueous ethanol solution.

[0014] Furthermore, plant-based compositions are used in cosmetics, hair care products, or weight loss products.

[0015] Furthermore, the cosmetics, hair care products, and weight loss products are lotions, creams, face masks, pastes, gels, and lotions.

[0016] The beneficial effects of this invention are as follows: Through the synergistic effect of loquat flower extract and white bud Qilan tea extract, reactive oxygen species can be effectively inhibited, DPPH can be cleared, hyaluronidase activity can be inhibited, and hexosamine enzyme release can be inhibited, thus better exerting the anti-inflammatory and antioxidant effects of loquat flower; by inhibiting the activity of testosterone-5α reductase and cyclic adenosine monophosphate (cAMP)-phosphodiesterase, a new use for the loquat flower extract composition is provided, namely, its use in hair care and weight loss.
