However, to date, the antiviral capability of Quillaja saponins has not been documented. Using extracts from the Chilean Soap Bark Tree (Quillaja Saponaria Molina) we document the anti-viral capacities of Quillaja saponins against HSV-1 and Vaccinia. The saponin was ineffective against Vaccinia Virus, however neutralized HSV-1 in a time and temperature dependent manner. In addition, Quillaja Saponins were determined capable of preventing cell-to-cell spread when introduced in solution to cell monolayers.ENM.S.
