Example Embodiment

[0029] Example 1 The extraction rate of Artemisia plants with different organic solvents

[0030] Take 100.0g of the above-mentioned three kinds of wormwood powder, and use 1000ml of 90% ethanol, 50% ethanol, acetone, chloroform, petroleum ether and deionized water to shake and extract 3 times under a water bath shaker at 40℃, each time use the amount of solvent Respectively 500ml, 300ml, 200ml, the extraction time was 3, 2, and 1 days respectively. The filtrate was combined and concentrated by a rotary evaporator to obtain the extract, weighed, and measured the extraction rate. The results are shown in Table 1.

[0031] Table 1 The extraction effect of different solvents on Artemisia plants

[0032]

[0033] From the results, the extraction effect of ethanol is significantly better than other organic solvents, especially the effect of 50% ethanol is better.

Example Embodiment

[0034] Example 2 The influence of different extraction methods on the extraction rate

[0035] Study the influence of soaking extraction method, continuous extraction method and ultrasonic extraction method on extraction rate. The data of the immersion extraction method adopts the data of Example 1.

[0036] The test method of continuous extraction method is as follows: Weigh 15.0g of three kinds of Artemisia powder, wrap it with filter paper, put it in a Soxhlet extractor, inject 150ml of 95% ethanol solution and acetone solution, and heat the water bath to 80℃, continuously After extraction for 6 hours, the extract was concentrated on a rotary evaporator to obtain an extract, which was weighed and the extraction rate was measured.

[0037] Ultrasonic extraction test method: Weigh 15.0g of three kinds of Artemisia powder and pour into a triangular flask, inject 150ml of 95% ethanol solution and acetone solution, seal, soak for 24 hours, and put in an ultrasonic cleaning machine for...

Example Embodiment

[0041] Example 3 The effect of different extraction methods on apple coloring

[0042] Take 1000 grams of dry powder prepared from mugwort, the solvent is 50% ethanol, the ratio of material to liquid is 1:10, and the extraction is carried out according to the soaking method, continuous extraction method, and ultrasonic extraction method in Examples 1 and 2. After several times, the extracts were finally combined and concentrated under reduced pressure to 1000ml to become the original drug containing 1g / ml of crude drug.

[0043] The test Fuji apple is a 10-year-old fruit tree, a single-branched plot, repeated 3 times, after removing the bag, 30 days and 15 days before the fruit harvest, the original medicine obtained by the three methods was diluted 200 times and 100 times respectively. Beihe 50 times sprayed the fruit trees, focusing on the fruit, and spraying until all the fruits are coated. Add 0.1% Tween-80 to the medicament, and use water plus Tween-80 as a control. The solu...

Abstract

The invention relates to a novel use of an artemisia extractive, particularly relates to the application of the artemisia extractive as a fruit coloring accelerant. The artemisia extractive contains the following components such as cinnamic acid, cumaric acid, flavone, flavonoid, vitamins and mineral elements, and the effective components can promote synthesis of anthocyanin so as to fulfill the purpose of promoting fruit coloring and has precise effect on fruit coloring.

Description

technical field [0001] The invention relates to a new application of Artemisia extract, in particular to the application of Artemisia extract as a fruit coloring accelerator. Background technique [0002] Artemisia annua extract has a long history of application in my country. It has the functions of protecting liver and gallbladder, lowering blood fat, antibacterial and anti-inflammatory, antimalarial, antipyretic and analgesic, enhancing immunity, anti-tumor, cell protection, etc., especially extracted from Artemisia annua Artemisinin has a special effect on the treatment of malaria, and it is an outstanding contribution of Chinese traditional medicine to world medicine. The application of modern technology to the research on the chemical constituents of Artemisia plants shows that: Artemisia plant extracts mainly contain volatile oils, polysaccharides, vitamins, minerals, cinnamic acids, coumarins, and flavonoids. The main components of volatile oil are various monoterpen...
