preparation example Construction

[0026] In the present invention, the preparation method of the fat-soluble extract of Brachydia zodiacum comprises the following steps:

[0027] (1) Homogenize the Brachydia zoster, filter to obtain the filtrate;

[0028] (2) Extract the filtrate with n-butanol, separate the n-butanol part, concentrate to extract, and obtain the fat-soluble extract of Ascidian breviputum.

[0029] In the invention, the Brachydia zoster is homogenized and filtered to obtain a filtrate. In the present invention, before the homogenization, the impurities and attachments of the Ascidian squirrel are preferably removed. Preferably in the present invention, the Brachydia zoster is crushed and then mixed with physiological saline for homogenization. In the present invention, the mass ratio of the Brachygnathus constellata to physiological saline is preferably 1:3-1:5, more preferably 1:4. In the present invention, the homogenate is preferably an ice-bath homogenate, and the ice-bath homogenate is ...

Embodiment 1

[0038] 1. Preparation of the extract of Brachydontida zodiac

[0039] Remove the impurities and attachments of Brachyptina zodiac, cut into small pieces with surgical scissors, add normal saline according to the ratio of 1:4 volume ratio of Brachydia zodiac: normal saline, and homogenize in ice bath for 3 times, and change the homogenate each time. A new ice-water bath was used to avoid the change of active substances caused by the increase of temperature. The slurry was filtered with a Buchner funnel and the filtrate was collected. The filtrate was extracted with n-butanol (volume ratio 1:3), repeated 3 times, the extracted n-butanol fractions were combined, concentrated under reduced pressure at 45°C to an extract, and the lipid-soluble extract of Brachydia zoster was obtained for future use.

Abstract

The invention provides a weight-loss and lipid-lowering composition and an application thereof, and relates to the technical field of biochemistry. The weight-loss and lipid-lowering composition of the invention comprises, in parts by weight, 6-15 parts of berberine hydrochloride and 1-5 parts by weight of berberine hydrochloride. A lipid-soluble extract of Ascidian constellation is obtained; the lipid-soluble extract of Ascidian constellation is obtained by homogenizing the Ascidian constellation, filtering to obtain a filtrate, extracting the filtrate with n-butanol and concentrating. The composition provided by the invention has the functions of significantly reducing body weight and regulating blood lipids, and can obviously prevent and treat hyperlipidemia, prevent obesity, reduce body weight, regulate abnormal lipoproteins, regulate lipid metabolism and reduce the incidence of coronary heart disease.

Description

technical field [0001] The invention relates to the technical field of biochemistry, in particular to a composition for weight loss and fat reduction and application thereof. Background technique [0002] Berberine hydrochloride is an isoquinoline alkaloid. Molecular formula [C 20 h 18 NO 4 ] + . Also known as berberine. It exists in many plants of 4 families and 10 genera such as Berberidaceae. Berberine can precipitate yellow needle-like crystals from ether. The melting point is 145°C. Soluble in water, insoluble in benzene, ether and chloroform. Chinese patent CN1939310A discloses a weight loss composition composed of berberine and oryzanol, which discloses that berberine has the effect of inhibiting adipogenesis, and inhibits the differentiation of preadipocytes by inhibiting the gene expression of PPARγ2; berberine hydrochloride (Berberine hydrochloride) has low solubility and is not easy to be absorbed by the human body, while oryzanol is a mixture of ferulic...
