Embodiment 1

[0036] The preparation method of the total extract of marina comprises the following steps:

[0037] Weigh about 100g of the dried marina fruit, crush it, add 95% methanol according to the liquid-to-solid ratio of 1g: 5mL, and extract by cold soaking at room temperature (20-30°C) for 3 times, each time for 48-72h. After combining the extracts, The solvent was recovered under reduced pressure at 45°C, and dried at room temperature to constant weight to obtain 37.0 g of the total marina extract, with an extraction rate of 36.3%.

Embodiment 2

[0039] The preparation method of the total extract of marina comprises the following steps:

[0040] Weigh about 100g of marina dried fruit, crush it, add 60% ethanol according to the liquid-to-solid ratio of 1g:5mL, and extract by cold soaking at room temperature for 3 times, each time for 48-72h. After combining the extracts, recover the solvent under reduced pressure at 55°C , and dried at room temperature to constant weight to obtain 32.5 g of the total extract of marina, with an extraction rate of 32.8%.

Embodiment 3

[0042] The preparation method of the total extract of marina comprises the following steps:

[0043] Weigh about 100g of the dried fruit of marina, crush it, add water according to the liquid-to-solid ratio of 1g:5mL, and extract by cold soaking at room temperature for 3 times, each time for 48-72h. After combining the extracts, recover the solvent under reduced pressure at 60°C, Dry to constant weight to obtain 29.0 g of marina total extract concentrate, with an extraction rate of 28.2%.

Abstract

The invention provides a Crataegus dahurica Koenhne ex Schneid fruit extractive as well as a preparation method and application thereof and belongs to the field of natural product chemistry. The preparation method of the Crataegus dahurica Koenhne ex Schneid fruit extractive comprises the following steps: 1) performing soaking extraction on Crataegus dahurica Koenhne ex Schneid fruits with an extraction solvent, and concentrating an obtained soaking extraction solution to obtain a total Crataegus dahurica Koenhne ex Schneid fruit extractive; 2) washing the total Crataegus dahurica Koenhne ex Schneid fruit extractive with a washing solvent after being dispersed with water to obtain a water phase to be extracted; 3) extracting the water phase to be extracted with a first organic solvent to correspondingly obtain a first organic solvent phase and a first water phase, and concentrating the first organic solvent phase to obtain a first Crataegus dahurica Koenhne ex Schneid fruit extractive; and 4) extracting the first water phase with a second organic solvent to obtain a second organic solvent phase, and concentrating the second organic solvent phase to obtain a second Crataegus dahurica Koenhne ex Schneid fruit extractive. The obtained Crataegus dahurica Koenhne ex Schneid fruit extractive has the functions of reducing blood fat and promoting digestion and can be applied to preparing drugs or health foods for reducing blood fat and/or promoting digestion.

Description

technical field [0001] The invention belongs to the field of natural product chemistry, and in particular relates to a marina extract and a preparation method and application thereof. Background technique [0002] Marina is the fresh and / or dried mature fruit of Crataegusdahurica Koenhne ex Schneid, a plant of the genus Crataegus in the family Rosaceae, also known as mianguo, swollen belly yellow, mianduluo, etc. Malina is a kind of wild fruit that Oroqen people eat daily. It tastes sweet and sour. It is often used as medicine in the folks. This medicinal material is widely distributed in the northeastern provinces and the Daxinganling area in China. It is concentrated in Heilongjiang Province and the eastern part of the Inner Mongolia Autonomous Region. It is also distributed in Shanxi, Mongolia, Russia and other places. It has rich plant resources and large fruit output. Use natural plant resources. At present, the research on the chemical constituents of marina only sta...
