Problems solved by technology

[0003] However, my country's ginger deep processing is relatively backward at present. Generally, ginger is processed into ginger oil and ginger powder, but the volatile ginger essential oil and gingerol in the ginger oil are not effectively separated, so that the active ingredients in the ginger extract cannot be obtained. Classified utilization not only has poor use effect, but also causes waste of resources

Embodiment 1

[0032] The present embodiment provides a kind of extracting method of active ingredient in ginger, a kind of extracting method of active ingredient in ginger, comprises the following steps:

[0033] (1) Ginger juice and minced ginger are obtained after the dried ginger is pulverized by an extrusion crushing device;

[0034] (2) Mix ginger juice and ginger powder, mix according to the ratio of 1g ginger to 8ml60% ethanol, and divide them into 3 groups, ultrasonic treatment for 13min, 15min, 20min respectively, and then carry out the above steps again on the centrifuged filter residue treatment, and then centrifuged to obtain the second filtrate and filter residue A, and the filtrate obtained by the first extraction and the second filtrate were combined to obtain filtrate A, wherein the treatment temperature was 50°C, the ultrasonic working power was 350W, and the centrifugal speed was 3600r / min. The time is 15 minutes;

[0035] (3) Filtrate A is mixed with an equal volume of p...

Embodiment 2

[0042] The present embodiment provides a kind of extracting method of active ingredient in ginger, a kind of extracting method of active ingredient in ginger, comprises the following steps:

[0043] (1) Ginger juice and minced ginger are obtained after the dried ginger is pulverized by an extrusion crushing device;

[0044] (2) Mix ginger juice and minced ginger, divide them into 3 groups, and mix them with 60% ethanol respectively, and the mixing ratios are 1:4, 1:5, 1:9, and divide them into 3 groups. Ultrasonic treatment for 15min, then the filter residue obtained by centrifugation was processed in the above steps again, and then centrifuged to obtain the second filtrate and filter residue A, and the filtrate obtained by the first extraction was combined with the second filtrate to obtain filtrate A, wherein the processing temperature was 50 ℃, the ultrasonic working power is 300W, the centrifugal speed is 3600r / min, and the centrifugal time is 15min;

[0045] (3) Filtrate...

Embodiment 3

[0052] Ginger essential oil and gingerol crude product are extracted according to the method among the embodiment 2, wherein in step (2), set and only carry out the control group of processing once with ultrasonic wave and process 3 times with ultrasonic wave, the ginger essential oil that it makes and gingerol extraction rate as shown in table 3:

[0053] table 3

[0054]

[0055] It can be seen from the above table that the extraction rate of active ingredients in the second extraction with ethanol is obviously higher than that in the first extraction with ethanol, while the extraction rate of active ingredients in the third extraction with ethanol is similar to the extraction rate of the active ingredients in the second extraction with ethanol, that is, using One-time ethanol extraction cannot effectively extract the active ingredients in ginger, and the second extraction can more thoroughly extract the active ingredients in ginger.

[0056] Wherein, the extrusion crush...

Abstract

The invention discloses a method for extracting active ingredients in ginger, and relates to the technical field of extraction of plant effective substances, comprising the following steps: (1) Grinding dried ginger with an extrusion crushing device to obtain ginger juice and ginger powder, and crushing the ginger powder until the 20-60 mesh sieve; (2) ginger juice and ginger powder are mixed, mixed according to the ratio of 1g ginger to 4-9ml ethanol, and ultrasonic treatment is performed for 13-20min to obtain filtrate A and filter residue A; (3) filtrate A and Equal volumes of petroleum ether were mixed, and allowed to stand for stratification, and the upper liquid was separated to obtain filtrate B, and the lower liquid was filtrate C; (4) Filtrate B and filtrate C were respectively subjected to suction filtration and concentration, and filtrate B was concentrated to obtain ginger essential oil , After the filtrate C was concentrated, the crude product of gingerol was obtained. The method for extracting active ingredients in ginger provided by the invention can effectively separate gingerol and ginger essential oil, and can improve the extraction rate of active ingredients in ginger.

Description

technical field [0001] The invention relates to the technical field of plant effective substance extraction, in particular to a method for extracting active ingredients in ginger. Background technique [0002] Ginger is a perennial herb of Zingiberaceae Zingiberaceae. It is an important spice seasoning in the world and a traditional medicinal and edible plant in Asia. And stomach anti-vomiting and other effects. Modern pharmacological research shows that ginger has the functions of promoting the secretion of digestive juice, protecting the liver and gallbladder, lowering blood sugar, lowering blood fat, anti-oxidation, anti-aging, anti-tumor, anti-inflammatory, anti-microbial, anti-radiation, and cardiovascular protection. It is by far the most important rhizome spice in international trade. The world trade volume exceeds 20,000 tons, and my country's annual export volume accounts for more than 40% of the world's total export volume. Its main active ingredients are volatil...
