Abstract

This study is aimed to evaluate the antiviral studies ofAloe pirottaeroot extracts in Vitro on Influenza A and B viruses, Picornaviruses, and Dengue virus. During this study, crude methanol extract (MeOH) and its organic solvent fractions including n-hexane (HxF), chloroform (CHF), ethyl acetate (EAF) and n-butanol (BuF) ofAloe pirottaeroot in different concentrations were prepared and evaluated for a cytopathic effect (CPE) inhibitory assay for influenza virus and picornavirus and an immunofluorescence assay (IFA) for dengue virus. In vitro test revealed thatAloe pirottaeroot extracts have shown important effects in reducing both A and B influenza viruses, HRV B14 and EV-71(H) in MDCK cells, and DENV-2 replication in Vero cells. EAF exhibit more potential inhibitory activity with selectivity index >7.2 >17.8 and >8.5 than positive controls AMT with selectivity index not determined (ND), >47.6 and ND and RBV with selectivity index >2.9, >5.3 and >5 against PR8, HK and Lee, respectively. EAF exhibits the strongest anti-HRV B14 and anti-EV-71(H) activity in MDCK cells. Crude MeOH extract, EAF and BuF at both concentrations exhibit strong inhibition of DENV-2 induced CPE where as CHF and HxF at 20 µg/ml exhibit strong inhibition of DENV-2 production. The findings show significant inhibitory effect ofAloe pirottaeroot on influenza A and B viruses, HRV B14 and EV-71(H), and DENV-2 replication.
