Ginkgo phenols exocarp refluxed with 70%ethanol extraction of active ingredients ginkgo phenols obtained with the crude extract with ether, 5% Na2CO3, 5% NaOH extraction , to obtain ginkgo phenols; In this study, using GC-MS identified the extract as ginkgo phenols. Bioassary to Ginkgo Phenols for the tested fungi showed that the Ginkgo Phenols was effective to Pellicularia rolfsii, in which the EC 50 was 1.36 mg·mL-1.
