Hypericum patulum extract and application thereof in preparation of product with inhibition effect on pancreatic lipase and/or alpha-glucosidase

The invention relates to the technical field of biology, and particularly discloses a hypericum patulum extract and application of the hypericum patulum extract in preparation of a product with an inhibiting effect on pancreatic lipase and/or alpha-glucosidase. The preparation method of the hypericum patulum extract comprises the following steps: taking traditional Chinese medicine hypericum patulum, drying, crushing, soaking in an organic solvent, and after soaking, carrying out ultrasonic-assisted extraction at 40-50 DEG C for 20-40 minutes; after the extraction is finished, separating an extracting solution, and concentrating and drying the extracting solution to obtain a hypericum patulum ultrasonic extraction product; and taking a hypericum patulum ultrasonic extraction product to obtain the hypericum patulum extract. Researches show that the hypericum patulum extract prepared by the preparation method of the hypericum patulum extract disclosed by the invention has an inhibition effect on pancreatic lipa
