Example Embodiment
[0018] Example 1
[0019] (1) Take the dried coconut fiber (1.0kg) and pulverize to 100 mesh (to obtain coconut bran), add 5.0kg of absolute ethanol, reflux and extract for 5 hours, then filter while hot to remove the filter residue, and the filtrate is concentrated under reduced pressure to obtain leaching paste;
[0020] (2) The extract obtained in step (1) is adsorbed on a macroporous resin column and eluted with ethanol with a volume fraction of 60-70%. Collect 4-6 times the column volume of the eluent, concentrate under reduced pressure, and dry under vacuum Obtained coconut bran extract (18.9g, hereinafter referred to as product A).
Example Embodiment
[0021] Example 2
[0022] (1) Take the dried coconut fiber (1.0kg) and crush it to 20 mesh (to obtain coconut bran), add 10.0kg of absolute ethanol, reflux and extract for 8 hours, filter while hot, remove the filter residue, and concentrate the filtrate under reduced pressure to obtain a leaching paste;
[0023] (2) The extract obtained in step (1) is adsorbed on a macroporous resin column and eluted with ethanol with a volume fraction of 60-70%. Collect 4-6 times the column volume of the eluent, concentrate under reduced pressure, and dry in vacuum Obtained coconut bran extract (20.2g, hereinafter referred to as product B).
Example Embodiment
[0024] Example 3 Free radical scavenging ability of test sample
[0025] According to the method of the prior art, test rutin, product A, product B, product A + rutin (the mass ratio of the two is 1:1), and product B + rutin (the mass ratio of the two is 1: 1) are free to hydroxyl And DPPH free radical scavenging ability, calculate the half inhibitory concentration (IC 50 Value), the following test results of the present invention were tested according to the method described in Chinese patent application number: 201310089721.X, see Table 1.
[0026] Table 1
[0027]
[0028] "+++" means the compound concentration is 0.1-1.0μg / mL, "++" means the compound concentration is 10-100μg / mL, "-" means the compound concentration is greater than 1×10 5 μg / mL.
[0029] The above experimental results show that products A and B have almost no free radical scavenging ability, but when they are mixed with rutin at a mass ratio of 1:1, it can significantly enhance the scavenging ability of rutin on f...
