Fig. 5. Feline calicivirus (FCV)-inactivating activities of Dracocephalum spp.-derived compounds. Compounds isolated from D. fruticulosum (A and B), D. nutans (C and D), and D. foetidum (E and F) were incubated with FCV suspensions for 48 h (A, C, and E) and 6 h (B, D, and F), respectively. Viral titer data are presented as the mean ± standard deviation (n = 3–7 per group). *p <0.05; **p <0.01 vs. the dimethyl sulfoxide (DMSO) control group (Student's t-test). TCID50, 50% tissue culture infectious dose.
