Embodiment 1

[0016] A peach kernel extract, comprising the steps of:

[0017] (1) After removing impurities from the peach kernels, blanch them in boiling water for 2 minutes, take them out and dry them naturally for later use;

[0018] (2) Grind the peach kernels treated in step (1) and pass through 80 meshes, then put them into an ethanol solution with a mass fraction of 85% that is 3 times the total mass, continuously reflux for 12 hours, and filter to obtain the extract and filter residue, and then carry out dealcoholization to the extract solution to obtain solution A for subsequent use;

[0019] (3) Put the filter residue obtained in step (2) into petroleum ether whose total mass is 4 times, soak and extract for 8 hours, take out the petroleum ether extract, and then perform petroleum ether removal operation to obtain solution B for later use;

[0020] (4) Mix the solution A obtained in step (2) and the solution B obtained in step (3) together, then add an equal volume of ethyl acet...

Abstract

The invention discloses peach kernel extract, and relates to the field of natural medicinal chemistry and the field of cosmetics. The peach kernel extract is prepared from ethyl alcohol, petroleum ether and ethyl acetate through sequential extraction. The prepared extract has a very good moisture preserving effect, can provide a very good moisture preserving function for skin horn cells, and can also absorb energy of ultraviolet rays and release the energy in the form of heat energy or visible light, and damage of the ultraviolet rays to skin is reduced. The peach kernel extract can be used in the cosmetics, has the effects of preserving and locking moisture, resisting bacteria and preventing the ultraviolet rays and makes the skin shiny and glossier.

Description

technical field [0001] The invention relates to the fields of natural medicinal chemistry and cosmetics, in particular to a peach kernel extract and its application. Background technique [0002] Peach kernel, the name of traditional Chinese medicine. It is the dry mature seed of peach Prunus persica (L.) Batsch or mountain peach Prunus davidiana (Carr.) Franch. of Rosaceae. Harvest the fruit after it is ripe, remove the pulp and core shell, take out the seeds, and dry in the sun. Widely cultivated throughout the country. It has the effects of promoting blood circulation and removing blood stasis, moistening the intestines and laxative, relieving cough and relieving asthma. For amenorrhea dysmenorrhea, abdominal mass in the abdomen, lung abscess and intestinal abscess, injury from falls, dryness of the intestine and constipation, cough and asthma. At present, peach kernel is mainly used in the field of traditional Chinese medicine, and it is rarely used in cosmetics for ...
