Abstract:
Objective: To investigate antiviral activity of maca to reduce viral load in kidney (MDCK) cells infected with influenza type A and B viruses (Flu-A and MFalud-inB-, Dreasrpbeyc ctiavneilny)e. Methods: Maca were extracted with methanol (1:2, v/v).

Results: The methanol extract of maca showed low cytotoxicity and inhibited influenza-induced cytopathic effect significantly, while viral load was reduced via inhibition of viral growth in MDCK infected cells. Maca contains potent inhibitors of Flu-A and Flu-B with a selectivity index [cytotoxic concentration 50%/IC50] of 157.4 and 110.5, respectively. Conclusions: In vitro assays demonstrated that maca has antiviral activity not only against Flu-A (like most antiviral agents) but also Flu-B viruses, providing remarkable therapeutic benefits.
