Leech preparation method and verification method for improving bioavailability

The invention relates to the technical field of physical analysis, in particular to a leech preparation method for improving bioavailability and a verification method. Stirring and mixing 3kg of leeches, and dividing the leeches into a first part of 0.5 kg of leeches and a second part of 2.5 kg of leeches for later use; respectively processing 0.5 kg of the first part of leech and 2.5 kg of the second part of leech to obtain 20 parts of samples; respectively titrating thrombin to 20 parts of the samples to obtain 20 verification data; according to the method, the influence of different processing methods on the antithrombin activity of the leeches is investigated, the antithrombin activity of the leeches is measured by adopting a thrombin titration method, a potential production and processing method of the leeches is explored, and the method is suitable for industrial production and processing of the leeches. The hirudin with higher content can be produced by better utilizing the existing leeches while the p
