Problems solved by technology

From the existing research reports, flavonoids can promote fruit coloring (patent application No. 200780018814.6, 200510094293.5), but flavonoids are extracted and purified, and the price is relatively high. Economic reasons limit their use. agricultural applications

Embodiment 1

[0029]Example 1 Different organic solvents to the extraction rate of Artemisia plants

[0030] Take 100.0 g of the above three Artemisia sample powders prepared above, and use 1000 ml 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 °C, each time with the amount of solvent 500ml, 300ml, and 200ml respectively, and the extraction time was 3, 2, and 1 day respectively. The combined filtrates were concentrated by a rotary evaporator to obtain extracts, weighed, and the extraction rate was measured. The results are shown in Table 1.

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

[0032]

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

Embodiment 2

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

[0035] The effects of soaking extraction, continuous extraction and ultrasonic extraction on the extraction rate were studied. The data of soaking extraction method adopts the data of embodiment 1.

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

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

Embodiment 3

[0041] Example 3 Effects of Different Method Extracts on Apple Coloring

[0042] Get 1000 grams of dry powder prepared by mugwort, the solvent is 50% ethanol, and the ratio of solid to liquid is 1:10. Extract according to the methods of soaking method, continuous extraction method, and ultrasonic extraction method in Examples 1 and 2. If it cannot be completed once, it can be separated. Multiple times, and finally combine the extracts, concentrate under reduced pressure to 1000ml, and become the original drug containing crude drug 1g / ml.

[0043] For the test Fuji apple is a 10-year-old fruit tree in the full fruit period, a single-branch plot, and repeated 3 times. After removing the bag, 30 days and 15 days before the fruit was harvested, the original medicine obtained by the three methods was diluted 200 times and 100 times respectively. Double and 50 times to spray the fruit trees, focusing on spraying the fruit until all the fruit is sprayed. Add 0.1% Tween-80 to the med...

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...
