1996•cabidigitallibrary.orgCrude extracts from leaves of Persea americana (Lauraceae), collected in Rio de Janeiro
and Bahia States, Brazil, presented a strong inhibitory activity against Aujeszky's disease
virus (ADV) in cell cultures. Lyophilized samples preserved their activities even when stored
for 5 years at-20° C. ADV showed a reduction of infectivity of 1.5 log after 30 min of direct
incubation with 200 µg/ml lyophilized crude extract. The addition of the extract
simultaneously with the virus inoculation was enough for effective inhibition.

Abstract
Crude extracts from leaves of Persea americana (Lauraceae), collected in Rio de Janeiro and Bahia States, Brazil, presented a strong inhibitory activity against Aujeszky's disease virus (ADV) in cell cultures. Lyophilized samples preserved their activities even when stored for 5 years at -20°C. ADV showed a reduction of infectivity of 1.5 log after 30 min of direct incubation with 200 µg/ml lyophilized crude extract. The addition of the extract simultaneously with the virus inoculation was enough for effective inhibition.
