AB  - In this study, high performance liquid chromatography (HPLC), ultraviolet (UV), 
      thermagravimetric analyzer (TGA), pyrolysis-gas chromatography-mass spectrometry 
      (Py-GC-MS), and scanning electron microscope (SEM) were used as measurement 
      techniques, contents of chemical composition, pyrolytic products, thermal 
      stability, morphological characterization of Ginkgo biloba leaves (GBL) acted as 
      the index, and physicochemical properties of GBL after enzymolysis based 
      ultrasound extraction (EBUE) and Soxhlet extraction were studied. The detection 
      results of chemical composition revealed that contents of general flavone, 
      soluble protein, soluble total sugar and protein in the GBL declined 
      significantly after EBUE, and contents of polyprenols and crude fat obviously 
      reduced as well after Soxhlet extraction. Py-GC-MS results indicated that total 
      GC contents of micromolecules with carbon less than 12 from 54.0% before EBUE 
      decline to 8.34% after EBUE. Total GC contents of long-chain fatty acids with 
      carbon less than 20 from 43.0% before EBUE reduced to 27.0% after Soxhlet 
      extraction. Thermal stability results showed that GBL after Soxhlet extraction 
      was easier to decompose than GBL before EBUE. SEM results illustrated that 
      surface structure of GBL was damaged severely after EBUE, compared with GBL 
      before EBUE, while organic solvent extraction had little influence on the 
      morphological characterization of GBL after Soxhlet extraction compared with GBL 
      after EBUE.
