The biological activity of methanolic the extracts of leaves, roots, leaf-derived callus, root-derived callus, ginkolide A, ginkgolide B, bilobalide and a commercial Ginkgo product (Tanakan) was assessed. Bioassays consisted of the Agrobacterium tumefaciens-induced potato tumor assay and a Kirby-Bauer microbial sensitivity assay with pure strains of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus pyogenes. Methanolic extracts of leaves, leaf-derived callus, root-derived callus, bilobalide and Tanakan inhibited tumor formation significantly, but more weakly than the positive control, camptothecin. No activity against E. coli was detected, but extracts from both callus types inhibited the growth of K. pneumonia, P. aeruginosa, S. aureus, S. epidermidis and S. pyogenes. All extracts and reference compounds inhibited the growth of S. pyogenes. Leaf and root tissues contained the highest levels of ginkgolide A, as compared to the callus tissues; leaf tissue contained more of all three marker compounds than the callus tissues.

The coronavirus disease 2019 (COVID-19) virus is spreading rapidly, and scientists are endeavoring to discover drugs for its efficacious treatment in China. Chloroquine phosphate, an old drug for treatment of malaria, is shown to have apparent efficacy and acceptable safety against COVID-19 associated pneumonia in multicenter clinical trials conducted in China. The drug is recommended to be included in the next version of the Guidelines for the Prevention, Diagnosis, and Treatment of Pneumonia Caused by COVID-19 issued by the National Health Commission of the People's Republic of China for treatment of COVID-19 infection in larger populations in the future.
