Figure 1From: Antiviral activity and possible mode of action of ellagic acid identified in Lagerstroemia speciosa leaves toward human rhinoviruses Isolation procedures of anti-HRV principle. The Lagerstroemia speciosa leaf methanol extract was sequentially partitioned into hexane-, ethyl acetate-, butanol-, and water-soluble portions. For isolation of active principles from the ethyl acetate-soluble fraction, viral cytopathic inhibition assay toward HRV-4 in HeLa cell was used.Back to article page
