Embodiment 1

[0017] Example 1: A Nitraria bark residue extract with anti-fatigue effect and its preparation method. The Nitraria skin residue is composed of steps such as selection and removal of impurities, degreasing, ultrasonic extraction, concentration, removal of impurities, centrifugation, and drying. After the skin dregs are selected and removed, pass through a 30-mesh sieve and make coarse powder to remove sand and stones; during degreasing, petroleum ether with a material-to-liquid ratio of 1:5 is refluxed at 50°C for 3 hours, and the solvent is recovered and dried for later use; during ultrasonic extraction, the temperature is controlled at 85°C , extract with 40% ethanol for 1 h under the condition of solid-liquid ratio of 1:10; filter with 80 mesh silk cloth; 0 Bx; mix chloroform and n-butanol at a ratio of 5:1, add 0.2 times the volume of the mixed solution to the concentrated solution, stir vigorously on a constant temperature magnetic stirrer for 30 minutes, and refrigerate a...

Embodiment 2

[0018] Example 2: A Nitraria bark residue extract with anti-fatigue effect and its preparation method. The Nitraria bark residue is composed of steps such as selection and removal of impurities, degreasing, ultrasonic extraction, concentration, removal of impurities, centrifugation, and drying. After the skin dregs are selected and removed, pass through a 40-mesh sieve and make coarse powder to remove sand and stones; during degreasing, petroleum ether with a material-to-liquid ratio of 1:10 is refluxed at 70°C for 2 hours, and the solvent is recovered and dried for later use; during ultrasonic extraction, the temperature is controlled at 90°C , extract with 50% ethanol for 2 hours under the condition of solid-liquid ratio of 1:20; filter with 100-mesh silk cloth; control the negative pressure at -0.07Mpa during concentration, heat at 70°C, and concentrate until the solid content is 30 0 Bx: Mix chloroform and n-butanol at a ratio of 5:1, add 0.6 times the volume of the mixed s...

Embodiment 3

[0019] Example 3: A kind of extract of Nitraria japonica skin residue with anti-fatigue effect and its preparation method. The Nitraria thorn residue is composed of steps such as selection and removal of impurities, degreasing, ultrasonic extraction, concentration, removal of impurities, centrifugation, and drying. After the skin dregs are selected and removed, pass through a 50-mesh sieve and make coarse powder to remove sand and stones; during degreasing, petroleum ether with a material-to-liquid ratio of 1:15 is refluxed at 90°C for 1 hour, and the solvent is recovered and dried for later use; during ultrasonic extraction, the temperature is controlled at 95°C , extract with 60% ethanol for 3 hours under the condition of solid-liquid ratio of 1:30; filter with 120 mesh silk cloth; 0 Bx; mix chloroform and n-butanol at a ratio of 5:1, add 1 times the volume of the mixed solution to the concentrated solution, stir vigorously on a constant temperature magnetic stirrer for 1.5h,...

Abstract

The present invention belongs to the deep processing field of wild nitraria tangutorum fruits, and particularly relates to a nitraria tangutorum skin residue extract with an anti-fatigue effect and a preparation method thereof. The preparation method includes the following steps: selecting nitraria tangutorum skin residues, carrying out deslagging, degreasing, extraction, filtration, concentration, purification, centrifugation and freeze-drying, and the like. According to the present invention, the skin residues obtained by juicing the wild nitraria tangutorum fruits from the Qaidam Basin in the Qinghai Province are used as a raw material to be processed into the extract, and the final extract is dark brown powder. Active ingredients of the wild nitraria tangutorum fruits can be retained; the extract has effects of tonifying spleen and stomach, helping digestion, calming the nerves and the like; and the nitraria tangutorum extract has a significant anti-fatigue effect. Besides, the present invention provides a perfect technical solution for comprehensive utilization of the wild nitraria tangutorum fruit byproducts, i.e., the skin residues, and greatly improves the resource utilization of the wild nitraria tangutorum fruits from the Qaidam Basin.

Description

technical field [0001] The invention belongs to the field of deep processing of wild Nitraria tangutata, and in particular relates to a Nitraria japonica skin dregs extract with anti-fatigue effect and a preparation method thereof. Background technique [0002] Nitraria is a wild shrub belonging to Tribulus terrestae. It mainly grows in the Gobi Desert and the edge of the desert. Nitraria resources are rich in output and widely distributed in my country, but they are relatively concentrated in the Qaidam area of ​​Qinghai, and the conditions for development and utilization are superior. The Nitraria in the Qaidam area is distributed in non-polluted areas above 3,000 meters above sea level, with resources of 1.5 to 2 million mu. The relatively concentrated distribution of Nitraria forest with development value is about 500,000 mu, and the annual production of Nitraria fruit is 6~2 million mu. 100,000 tons, with an annual output of more than 20,000 tons of Nitraria pomace re...
