Abstract: To investigate the effect of purple corn anthocyanins (PCA) on inhibiting infectious bovine rhinotracheitis virus (IBRV) in vitro, the toxicity of PCA on madin-darby bovine kidney cells (MDBK) was measured by observation of cytopathic effect (CPE).Then the inhibition effects of PCA on replication of IBRV were investigated within safe concentrations by MTT assay. The results showed the maximum safe concentration of PCA on MDBK cell was 262.14 μg/mL, whereas PCA could apparently inhibit the replication of IBRV on MDBK cells in very low dose (7.8125 μg/mL). The median inhibitory concentration (TC50 and IC50) of PCA to MDBK and IBRV was 262.14 and 11.38 μg/mL,individually. On consequence, the treatment index (TI) was calculated as 23.04. These data demonstrated that PCA had the function of anti-IBRV, and suggested that purple corn could be as a feed material for prophylaxis and treatment of infectious bovine rhinotracheitis in dairy cows.
