Embodiment 1

[0069] 10 kg of apocynum leaves (dry weight) are removed from impurities (vibrating grading sieve can be used), washed with water for 15 minutes; continuous countercurrent extraction is used, 160 kg of water is added, the extraction temperature is 45-50 °C, and the extraction time from feeding to discharging is controlled for 60 minutes. Obtain the filtrate through coarse filtration equipment; add 0.1 kg of chitosan flocculant to the filtrate, let it stand for 5h, centrifuge at a high speed in a tube bundle centrifuge, remove the precipitate, and obtain 120 kg of extract clear liquid; vacuum concentration, the concentration ratio is 6:1, v / v, D101 macroporous resin on the concentrated solution, washed with distilled water until colorless, eluted with 75% ethanol, and the eluent was detected to collect active ingredients, concentrated in vacuo, spray-dried to obtain 1.2 kg of Apocynum apocynum extract, and detected the total flavonoid content 32.6 wt%.

Embodiment 2

[0071] 100 kg of fresh leaves of Apocynum apocynum are removed from impurities (vibrating grading sieve can be used), washed with water for 15 minutes; continuous countercurrent extraction is used, 100 kg of water is added, the extraction temperature is 55-60 ° C, the extraction time is 45 minutes from feeding to discharging, and the extraction is carried out through coarse filtration. The filtrate was obtained from the equipment; the filtrate was added with 0.2 kg of chitosan flocculant, left to stand for 8 hours, centrifuged at a high speed in a tube bundle centrifuge to remove the precipitate, and 150 kg of the extract clear liquid was obtained; vacuum concentration, the concentration ratio was 5:1, v / v, concentrated AB-8 macroporous resin on the liquid, washed with distilled water until colorless, eluted with 80% ethanol, and the eluent was detected to collect active ingredients, concentrated in vacuo, spray-dried to obtain 1.4 kg of Apocynum apocynum extract, and the total ...

Embodiment 3

[0072] Embodiment 3: the application of apocynum extract in cream cosmetics

[0073] Moisturizing lotion formula and production process:

[0074]

[0075] Mix group A and heat to 75°C; mix group B and heat to 75°C. Under stirring, add group A to group B for emulsification, and add essence when the temperature drops to 45°C. After passing the test, it is packed.

Abstract

The invention belongs to the field of herbal cosmetic additives and discloses an apocynum venetum extract, a preparation method thereof and application thereof to cosmetics. The apocynum venetum extract is prepared by the following steps of: removing impurities from dogbane leaves and washing the dogbane leaves; performing continuous countercurrent extraction for 30 to 90 minutes at the temperature of between 45 and 70 DEG C and then filtering to obtain filtrate, wherein the weight ratio of the dogbane leaves based on the dried weight to water is 1:8 to 1:20; adding a chitosan flocculating agent into the filtrate, standing, performing centrifugation and removing precipitates to obtain the clear solution of an extract; performing vacuum concentration; washing macroporous resins on the concentrated solution with distilled water to colorless; performing elution with ethanol at the concentration of 20 to 85 percent; detecting the eluent and collecting active ingredients; and spray drying to obtain the apocynum venetum extract with the total flavonoid content of over 30 percent. The apocynum venetum extract can be applied to developing functional cosmetics with effects of skin peroxidation resistance, senility delay, whitening, radiation resistance, sun protection, inflammation resistance, allergic resistance, bacterial inhibition, moistening, moisture maintenance and the like.

Description

technical field [0001] The invention belongs to the field of natural plant cosmetic additives, and relates to an extract of apocynum apocynum and its preparation method and application in cosmetics.
