Abstract:
Object To study the ultrastructure destruction of plants in the process of microwave assisted solvent extracion and its mechanism.Methods Cell structures of fresh leaves of Ginkgo biloba L. were observed by transmission electron microscpoe.Results The cell structure changed when the leaves were under microwave radiation or soaked by solvents or heated, such as plasmoysis, destruction of cell organellaes, disappearance of starch grain and so on, while the cell wall was not broken both in microwave assisted solvent extraction and in traditional heating extraction.Conclusion Microwave radiation could lead to the relaxation of the cell structures, but not be enough to make the cell wall broken.
