Embodiment 1

[0047] 1) Collect fresh crocodile fat, remove impurities, wash and pulverize.

[0048] 2), adopt the following method to prepare Chinese herbal medicine liquid:

[0049] 2.1. Weigh the raw materials of Chinese herbal medicine according to the following parts by weight and soak them in water respectively for 6 hours: 15.0 parts of tangerine peel; 0.01 part of other medicinal materials;

[0050] 2.2. Add water to decoct tangerine peel, ginger, paeonol, pomegranate peel, licorice, chrysanthemum, and honeysuckle respectively. The amount of water added is 10 times the weight of the original medicinal materials. The decoction time is 20 minutes, and the decoction is poured out for storage; Boil the same amount of water for the same time, three times in total;

[0051] 2.3. The three decoctions are combined and concentrated until the water content reaches 5 times of the total weight of the original medicinal materials to obtain the Chinese herbal medicine liquid.

[0052] 3) Mix th...

Abstract

The invention provides a method for extracting antioxidant crocodile grease. Compared with the prior art, not only is the problem that the grease is easily oxidized solved, but also a potential safety hazard caused by adding of a synthetic antioxidant to the grease is avoided, and green, healthy and environment-friendly ideas are accorded. IC50 is the concentration of the required antioxidant when the removal rate is 50%, and frequently applied to comparison of the ability for removing DPPH.free radical, and the half maximal inhibitory concentration (IC50) is determined by drawing a curve according to the removal rate of different concentrations of antioxidants. The IC50 is smaller in value, which indicates that the oxidation resistance is stronger and the ability of removing free radical is stronger. The crocodile grease extracted by the traditional method (control group) is detected by adopting the DPPH method and compared with the grease product obtained in the embodiments 1,4 (experimental group) disclosed by the invention in the antioxidant activity; the determination result displays the crocodile grease IC50=24.920mg / mL extracted by the traditional method, a final grease product IC50=14.138mg / mL obtained by the embodiment 1, and the final grease product IC50=14.545mg / mL obtained by the embodiment 4. The antioxidant activity of the final crocodile grease product extracted by the Chinese herbal medicine soup is obviously improved.

Description

technical field [0001] The invention relates to a method for extracting antioxidant crocodile oil. Background technique [0002] 1. Chinese alligator and its oil [0003] In my country, there are more than 3,000 years of records about the alligator, and the medicinal history of the alligator has a long history. "Compendium of Materia Medica" records that the "A" of the crocodile (that is, alligator) is mainly used for the treatment of trusted subordinates and abdominal pain; accumulation of volts; cold and heat; women's lower abdomen with yin and yin pain, metrorrhagia, five colors of blood and sores and scabies; Don't stand on the ground; don't record dampness, evil spirits, various gu, abdominal pain and malignant sores; its fat can mainly cure wind and malignant sores; its meat can cure abdominal diseases and malignant sores." [0004] 2. Oxidation of oil [0005] The effects of light, heat, oxygen in the air, water and enzymes in the oil often make the oil go bad. An...
