Method for identifying production place of Scylla paramamosain

The invention discloses a method for identifying the production place of Scylla paramamosain based on metabonomics research means, and belongs to the technical field of identification of the production place of Scylla paramamosain. The main steps comprise: selecting a plurality of Scylla paramamosain with different production places, analyzing the composition of the small molecule metabolites in the aqueous phase extracts of the Scylla paramamosain muscle, carrying out multi-variable statistical analysis on the 1H NMR data by using OPLS-DA, establishing an OPLS-DA model to obtain the characteristic metabolites of the Scylla paramamosain with different production places, and distinguishing the Scylla paramamosain with different production places by using the characteristic metabolites. Compared to the method in the prior art, the method of the present invention has the following advantage that the changes of the small molecule substances in the total extracts of the Scylla paramamosainwith different production
