* NS3 helicase activity in the presence of extract is expressed as a percentage of control in the absence of extract (100%); The sample with the strongest inhibition against NS3 helicase is in bold, underlined font; samples with relatively strong inhibition against NS3 helicase (<50%) are underlined.
