Problems solved by technology

According to the above survey of weed damage in wheat fields, it can be judged that the number of ghost lights is huge, and it is also quite difficult to remove weeds in farmland. Excessive use of herbicides not only does great damage to the wheat field itself, but also greatly increases environmental pollution. The problem is very serious

Embodiment 1

[0025] 1. Extraction: Take the dried whole grass of the ghost lamp, cut it into pieces, and cut the length of 1.5cm, pass through No. 1 sieve to remove the soil residue, add 10 times the amount of 95% ethanol extraction solvent per kilogram of medicinal materials, and extract 3 times at a constant temperature of 80 °C. Each time for 2 hours, a 95% ethanol solvent extract was obtained; the extracts were combined and concentrated under reduced pressure to obtain a concentrate.

[0026] 2. Extraction: add 8 times the weight of the concentrate to suspend in distilled water, suspend with an ultrasonic oscillator to obtain a suspension, add 1.5 times the volume of petroleum ether to the suspension to extract 3 times, combine the petroleum ether extracts, and recover the solvent under reduced pressure , to obtain petroleum ether extract (ie the product of the present invention).

Embodiment 2

[0028] 1. Extraction: Take the dried whole plant of the ghost lamp, cut it into pieces, the length of the segment is about 1cm, pass through No. 1 sieve to remove the soil residue, add 8 times the amount of 75% ethanol extraction solvent per kilogram of medicinal materials, and extract by constant temperature reflux twice, each time After 1 hour, a 75% ethanol solvent extract was obtained; the extracts were combined and concentrated under reduced pressure to obtain a concentrate.

[0029] 2. Extraction: add 6 times the weight of the concentrate to suspend in distilled water, suspend with an ultrasonic oscillator to obtain a suspension, add 1 volume of petroleum ether of the suspension to extract twice, combine the petroleum ether extracts, and recover the solvent under reduced pressure , to obtain petroleum ether extract (ie the product of the present invention).

Embodiment 3

[0031] 1. Extraction: Take the dried whole plant of the ghost lamp, cut it into pieces, the length is about 2cm, pass through No. 1 sieve to remove the soil residue, add 9 times the amount of 95% ethanol extraction solvent per kilogram of medicinal materials, and extract at constant temperature for 3 times, each time After 2 hours, a 95% ethanol solvent extract was obtained; the extracts were combined and concentrated under reduced pressure to obtain a concentrate.

[0032] 2. Extraction: add 7 times the weight of the concentrate to suspend in distilled water, suspend with an ultrasonic oscillator to obtain a suspension, add 2 times the volume of petroleum ether of the suspension to extract 3 times, combine the petroleum ether extracts, and recover the solvent under reduced pressure , to obtain petroleum ether extract (ie the product of the present invention).

Abstract

The invention discloses a preparation method and application of a traditional Chinese medicine extract capable of being used for preparing an antioxidant. The preparation method comprises the following steps: 1, extracting; and 2, extraction. The traditional Chinese medicine extract which is prepared by the method and can be used for preparing the antioxidant is used for preparing the antioxidant. The glehnia littoralis extract disclosed by the invention is prepared by taking single dry whole herb of botrychium variegatum as a raw material through the steps of refluxing, extracting, concentrating and the like. The extraction process is simple and low in cost. The results of GC-MS (Gas Chromatography-Mass Spectrometer) and antioxidant activity experiments show that 22 chemical components are totally identified from the ghost lighting extract disclosed by the invention and mainly contain fatty acid compounds, fatty alcohol compounds and vitamin compounds, and the half clearance concentrations IC50 of the chemical components to DPPH free radicals and ABTS + free radicals are respectively 208.69 mu g / mL and 146.00 mu g / mL.

Description

technical field [0001] The invention belongs to the technical field of natural antioxidants, and in particular relates to the preparation and application of a traditional Chinese medicine extract that can be used to prepare antioxidants. Background technique [0002] Antioxidants refer to food additives that can prevent or delay the oxidation of food, improve the stability of food and prolong the storage period. . Humans have a long history of using antioxidants. As early as BC, there were records of drinking green tea (containing natural antioxidant tea polyphenols). Antioxidants are widely used in atherosclerosis, diabetes, kidney disease and other fields. At present, antioxidants are mainly used in industrial production, food processing and storage, cosmetic daily necessities production and storage, prevention and treatment of various diseases, etc. They are almost ubiquitous, widely used, and used in huge amounts. Antioxidants are mainly divided into synthetic and nat...
