Embodiment 1

[0019] Snow chrysanthemum dry powder 20g, at room temperature (10-30°C) cold-soaked in 200ml of 30% ethanol, ultrasonically extracted twice, 10min each time (500W), combined the filtrates, recovered the solvent under reduced pressure to dryness, and extracted An appropriate amount of the substance was prepared into a 0.5mg / ml solution for later use, and its ability to scavenge DPPH free radicals was measured, so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0020] Result: IC of the scavenging DPPH free radical ability test of the crude extract of Snow Chrysanthemum 50 It was 428.3 μg / mL.

Embodiment 2

[0022] 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 ability to scavenge DPPH free radicals is measured, so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0023] Result: IC of the scavenging DPPH free radical ability test of the crude extract of Snow Chrysanthemum 50 It was 120.8 μg / mL.

Embodiment 3

[0025] 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 ability to scavenge DPPH free radicals is measured, so as to compare with the activity of the active part of the snow chrysanthemum prepared later.

[0026] Result: IC of the scavenging DPPH free radical ability test of the crude extract of Snow Chrysanthemum 50 It was 51.2 μg / mL.

Abstract

The invention relates to an application of a plant extractive in the field of a cosmetic with an anti-ageing effect. The invention discloses an application of a coreopsis tinctoria active part to the cosmetic with the anti-ageing effect. A preparation method of the coreopsis tinctoria active part 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 extractive; adsorbing the coreopsis tinctoria crude extractive through macroporous adsorption resin, eluting with the ethanol, collecting flow components, and evaporating to obtain the coreopsis tinctoria active part. The coreopsis tinctoria active part is a natural plant antioxidant. The coreopsis tinctoria active part has no side effects on a human body and can be used for preparing the cosmetic with the anti-ageing effect.

Description

technical field [0001] The invention relates to the fields of plant extracts and daily chemicals, in particular to the application of active parts of snow chrysanthemum in the field of anti-aging 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 mechanis...
