Fig. 1From: Anti-influenza virus activity of extracts from the stems of Jatropha multifida Linn. collected in MyanmarEffect of extracts from the stems of J. multifida on the viability of MDCK cells infected with influenza A H1N1 virus. H2O, EtOAc, Hex, and CHCl3 extracts from the stems of J. multifida (0.8-25 μg/mL in DMSO) were mixed with or without (virus-) influenza A H1N1 virus (A/PR/8/34) (MOI; 10), and added to MDCK cells. DMSO (0.008-0.5%) and (+)-(S)-bakuchiol (bakuchiol; 0.8-25 μM in DMSO) were used as negative and positive controls, respectively, for the inhibition of influenza A viral infection. After incubation for 4 days, cell viability was determined by naphthol blue black staining. Data are representative of three independent experiments, and the results were found to be reproducibleBack to article page
