    • Phenolic polymers are prepared by oxidizing and polymerizing starting organic compounds comprising at least one hydroxyl group and at least one carbonyl group or at least two hydroxyl groups on an aromatic structure. One or more inorganic compounds or salts is added and the solution is allowed to stand at about 20null C. to 80null C. for a period of about at least 2 hours. Salt molecules as well as starting compounds and other low molecular-weight materials below about 500 to about 10,000 daltons are removed from the product solution. Purified phenolic polymers are prepared in concentrated aqueous solution or in dried powder form in a final step, if necessary. The resultant phenolic polymers exhibit physicochemical properties strongly resembling those of typical commercially-available natural-product soil extracts. The materials are active influenza anti-viral agents, and are effective in anti-viral compositions for treating or preventing influenza viral diseases.
    • 通过在芳族结构上氧化和聚合包含至少一个羟基和至少一个羰基或至少两个羟基的起始有机化合物来制备酚醛聚合物。 加入一种或多种无机化合物或盐,并将溶液在约20℃至80℃下静置约至少2小时。 从产品溶液中除去盐分子以及起始化合物和低于约500至约10,000道尔顿的其它低分子量材料。 如果需要,在最终步骤中,将浓缩的水溶液或干燥粉末形式的纯化酚醛聚合物制备。 所得到的酚类聚合物显示出与典型的商业上可获得的天然产物土壤提取物相似的物理化学性质。 这些材料是活性流感抗病毒剂,并且在用于治疗或预防流感病毒性疾病的抗病毒组合物中是有效的。
