Embodiment 1

[0019] (1) Take the dried coconut fiber (1.0kg) and pulverize it to 100 mesh (to obtain coconut peat), add 5.0kg of absolute ethanol, and after reflux extraction for 5 hours, filter while it is hot to remove the filter residue, and the filtrate is concentrated under reduced pressure to obtain the soaked paste;

[0020] (2) The medicinal extract obtained in step (1) is adsorbed by a macroporous resin column, eluted with ethanol with a volume fraction of 60-70%, collecting 4-6 times the eluent of the column volume, concentrating under reduced pressure, and drying in vacuo Get coconut bran extract (18.9g, hereinafter referred to as product A).

Embodiment 2

[0022] (1) Take the dried coconut fiber (1.0kg) and pulverize it to 20 mesh (to obtain coconut peat), add 10.0kg of absolute ethanol, and after reflux extraction for 8 hours, filter while it is hot to remove the filter residue, and the filtrate is concentrated under reduced pressure. paste;

[0023] (2) The medicinal extract obtained in step (1) is adsorbed by a macroporous resin column, eluted with ethanol with a volume fraction of 60-70%, collecting 4-6 times the eluent of the column volume, concentrating under reduced pressure, and drying in vacuo Get coconut bran extract (20.2g, hereinafter referred to as product B).

Embodiment 3

[0024] The free radical scavenging ability of embodiment 3 test samples

[0025] According to the method of the prior art, respectively test rutin, product A, product B, product A+rutin (the mass ratio of the two is 1:1), product B+rutin (the mass ratio of the two is 1:1) to hydroxyl free Radical and DPPH free radical scavenging ability, calculate the half-inhibitory concentration (IC 50 value), the following test results of the present invention are tested according to the method recorded in Chinese patent application number: 201310089721.X, see Table 1.

[0026] Table 1

[0027]

[0028] "+++" indicates that the compound concentration is 0.1-1.0 μg / mL, "++" indicates that the compound concentration is 10-100 μg / mL, and "-" indicates that the compound concentration is greater than 1×10 5 μg / mL.

[0029] The above experimental results show that the products A and B themselves have almost no free radical scavenging ability, but when they are mixed with rutin at a mass rat...

Abstract

The invention relates to coconut chaff extract and application thereof in preparing an antioxidant. The coconut chaff extract is prepared through a following method comprising the following steps: (1)taking coconut chaff, adding 5 to 10 mass times of absolute ethanol, immediately filtering after carrying out reflux extraction for 5 to 8 hours, removing filter residue, and carrying out vacuum concentration on filtrate, thus obtaining an extract; (2) carrying out macroporous resin column adsorption on the extract obtained in the step (1), eluting by using ethanol of which the volume percentageis 60 to 70 percent, collecting 4 to 6 column volume times of eluate, carrying out vacuum concentration, and carrying out vacuum drying, thus obtaining the coconut chaff extract. The coconut chaff extract disclosed by the invention is capable of enhancing the scavenging capacity of rutin on hydroxyl free radicals and DPPH (2,2-diphenyl-1-picrylhydrazyl) free radicals, can be developed and used forpreparing the antioxidant, and can be used in the fields of medicine, food, cosmetics and the like.

Description

technical field [0001] The invention belongs to the field of whitening and sun protection, and in particular relates to a coconut bran extract and its application in synergistic anti-oxidation. Background technique [0002] Coconut (Cocos nucifera L.) is a monocotyledonous plant of the genus Cocos in the palm family, and is a tropical economic crop with great development value. Coconut meat is edible and can also be used for oil extraction, and coconut water (endosperm) can be used for beverages and the like. Coconut husk and coconut peat (i.e. coconut fiber powder) are by-products of coconut deep processing. At present, coconut peat is mainly used in agriculture and forestry as a cultivation substrate, and there are no reports on other applications. The present invention uses an organic solvent to extract coconut bran, and finds that the extract has the ability to enhance the ability of rutin to clear free radicals. Therefore, the coconut bran extract can be developed to p...
