Embodiment 1

[0029] The preparation method of the total extract of Emma comprises the following steps:

[0030] Weigh about 3.8kg of the dried fruit of Emma, ​​add methanol according to the ratio of 1g:5mL liquid to material, extract by cold soaking at room temperature (20-30°C) for 3 times, each time for 48-72h, and extract by hot reflux (60-70°C) Once, after merging the extracts, the solvent was recovered under normal pressure, and dried at room temperature to constant weight to obtain 1.15 kg of the total extract of Emerald, with an extraction rate of 30.4%.

Embodiment 2

[0032] The preparation method of the first aqueous phase of Emma comprises the following steps:

[0033] 1) According to the preparation method provided in Example 1, obtain the total extract of Emerald;

[0034] 2) Disperse the extract (904.8g) of the total extract of Emma in water, add petroleum ether at a volume ratio of 1:1 and extract continuously for 3 to 5 times, and obtain the petroleum ether phase and the first water phase correspondingly. Concentrate and dry under reduced pressure to obtain 19.4 g of emerald petroleum ether degreased product, with a yield of 0.5%. Correspondingly, the obtained first aqueous phase is 885.4 g, with a yield of 29.4%.

Embodiment 3

[0036] The preparation method of the second extract of Emma comprises the following steps:

[0037] 1) According to the preparation method provided in step 2) of Example 2, the first aqueous phase was obtained;

[0038] 2) Extract the first aqueous phase with ethyl acetate at a volume ratio of 1:1 for 4 to 6 times until the extract is colorless, corresponding to the second organic solvent phase and the second aqueous phase; the second aqueous phase is concentrated under reduced pressure After drying, 874.2 g of the second extract of Emma was obtained, with a yield of 28.9%.

[0039] 2. Verification test of the digestion-promoting function of Emma extract

Abstract

The emerald extract disclosed by the invention and its preparation method and application belong to the field of natural product chemistry. The emerald extract disclosed by the invention includes the total extract of emerald and the second extract of emerald without fat-soluble impurities, both of which have the function of promoting digestion, and can be used to prepare medicine or health food with promoting digestion. The present invention also provides a method for preparing the extract of Emme, comprising the steps of: 1) soaking and extracting the fruit of Emme with an extraction solvent, and concentrating the obtained soaking extract to obtain the total extract of Emme; 2) extracting the fruit of Emme After the extract is dispersed in water, it is first degreased with petroleum ether to obtain the first water phase; 3) the obtained first water phase is extracted with ethyl acetate to remove impurities, and the second water phase is correspondingly obtained, and the second water phase is concentrated under reduced pressure. Get the second extract of Emma. The method has mild extraction conditions, is environmentally friendly, is simple and easy to implement, can retain and enrich active ingredients to the greatest extent, and has low cost and high yield.

Description

technical field [0001] The invention belongs to the field of natural product chemistry, and in particular relates to an extract of emmerald and its preparation method and application. Background technique [0002] Since the 21st century, people's living standards have continued to improve and the pace of life has accelerated. More and more people have begun to pay attention to health issues, especially some chronic diseases such as accelerated aging, indigestion, obesity, etc. The incidence of these diseases has been greatly reduced. people's quality of life. At present, although there are many drugs for the treatment of gastrointestinal diseases clinically, the half-life of the drugs is short, and the long-term application has many side effects. Therefore, it is necessary to find new drugs or health foods with good digestion-promoting activity and low toxic and side effects. [0003] Emmo is a berry often eaten by Oroqen people. It matures in autumn, and the fruit is blac...
