Embodiment 1

[0018] Snow chrysanthemum dry powder 20g, at room temperature (5 ~ 30 ℃) in 200ml of ethanol with a volume concentration of 30% cold soaking, ultrasonic extraction twice, each time 30min (500W), take the filtrate and combine, recover the solvent under reduced pressure until dry, take the extraction An appropriate amount of the substance was prepared into a 0.5mg / ml solution for later use, and its tyrosinase inhibitory effect was determined so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0019] Result: IC of the tyrosinase inhibitory effect of the crude extract of Snow Chrysanthemum 50 1.85mg / ml.

Embodiment 2

[0021] Snow chrysanthemum dry powder 20g, at room temperature with 60% ethanol 200ml cold soaking, ultrasonic extraction 2 times, each time 30min (500W), take the filtrate and combine, recover the solvent under reduced pressure to dryness, take an appropriate amount of extract, and prepare 0.5 The mg / ml solution is ready for use, and its tyrosinase inhibitory effect is determined, so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0022] Result: IC of the tyrosinase inhibitory effect of the crude extract of Snow Chrysanthemum 50 It was 1.07mg / ml.

Embodiment 3

[0024] Snow chrysanthemum dry powder 20g, at room temperature with 70% ethanol 200ml cold soaking, ultrasonic extraction 2 times, each time 30min (500W), take the filtrate and combine, recover the solvent under reduced pressure to dryness, take an appropriate amount of extract, and prepare 0.5 The mg / ml solution is ready for use, and its tyrosinase inhibitory effect is determined, so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0025] Result: IC of the tyrosinase inhibitory effect of the crude extract of Snow Chrysanthemum 50 It is 0.92mg / ml.

Abstract

The invention relates to a plant extract and application of the plant extract in the field of a cosmetic with a whitening effect. The invention discloses a coreopsis tinctoria active part. A preparation method comprises the following steps of: taking coreopsis tinctoria dried powder, extracting with ethanol, combining filtrates, recovering a solvent in a decompressed manner, so as to obtain a coreopsis tinctoria crude extract; absorbing the coreopsis tinctoria crude extract through macroporous adsorption resin, eluting with the ethanol, collecting flow components, and evaporating to obtain the coreopsis tinctoria active part. With the adoption of the method, the coreopsis tinctoria active part is obtained and is the natural plant extract capable of restraining the tyrosinase. The coreopsis tinctoria active par has no side effect on a human body and can be used for preparing the cosmetic with the whitening effect.

Description

technical field [0001] The invention relates to the field of plant extracts and daily chemicals, in particular to the active part of snow chrysanthemum and its application in the preparation of whitening cosmetics. Background technique [0002] In recent years, with the improvement of people's living standards and aesthetic standards, more and more people pursue and yearn for white and clean skin. Therefore, the research and development of whitening cosmetics and skin whitening preparations that can prevent spots and pigmentation caused by sunlight and other reasons are increasingly being paid attention to by cosmetics manufacturers and researchers in various countries. Whitening cosmetics have become a skin care product. One of the mainstream varieties of cosmetics. [0003] However, with the frequent occurrence of poisoning incidents of chemically synthesized cosmetics, people began to be keen on plant cosmetics and beauty methods returning to nature. [0004] Whitening ...
