Abstract

The invention relates to the technical field of natural medicinal chemistry, and particularly discloses an effective part of a syzygium jambos fruit and a preparation method thereof and an applicationof the effective part in preparing a medicine or a food with hypoglycemic effect. The preparation method of the effective part of the syzygium jambos fruit comprises the following steps: an alcohol extraction step: taking the dried syzygium jambos fruit, and extracting an ethanol extract of the syzygium jambos fruit with an ethanol solution; an extraction step: extracting the ethanol extract of the syzygium jambos fruit with ethyl acetate to obtain an ethyl acetate extraction part; an ODS column chromatography step: extracting the ethyl acetate extract onto the ODS chromatography column, firstly eluting the material with a solvent A and performing removal of impurities; eluting the material with a solvent, and collecting the elution part of the solvent B, and performing concentration anddrying to obtain the effective part of the syzygium jambos fruit.

Description

technical field [0001] The invention relates to the technical field of natural medicine chemistry, in particular to an effective part of rose apple fruit, a preparation method thereof and an application in preparing medicine or food with hypoglycemic effect. Background technique [0002] Diabetes is a metabolic disease characterized by chronic hyperglycemia caused by a variety of etiologies. The metabolic disorder of sugar, fat and protein in diabetic patients can lead to a series of chronic complications such as hypertension, kidney disease and vascular disease. Diabetes has become a A worldwide public health problem that seriously threatens human health. According to the latest 8th edition of Diabetes Atlas released by the International Diabetes Federation (IDF), about 425 million adults around the world suffer from diabetes in 2017. 1 diabetes patient dies, and the number of people who die from diabetes in the world exceeds the sum of the deaths from malaria, tuberculosi...
