<h3>三叶青是中国特有珍稀名贵的中药，主要分布在长江以南，以福建为主，是福建地区传统习用青草药。</h3> <h3>化学研究表明三叶青主要含有异荭草素、荭草素、牡荆素鼠李糖苷、牡荆素、异牡荆素等碳苷类化合物，北京中医药大学的研究表明牡荆素、荭草素能够通过影响流感病毒活性而发挥抗病毒作用。</h3> <h3>中国科学院****研究所利用三叶青提取物治疗感染仙台病毒、流感病毒和滤泡性口炎病毒的小白鼠和鸡胚成纤维细胞来研究三叶青抗病毒作用，试验结果表明：三叶青提取物无论在组织培养细胞上或小白鼠体内均显示出不同程度的抗病毒作用。在组织培养中，三叶青提取物能较强地抑制流感病毒的繁殖、对仙台病毒具有明显的抗病毒作用，对滤泡性口炎病毒有很强的抑制作用。在小白鼠试验中，由于小白鼠机体防卫系统的作用，调节功能完善，在一定的药物浓度范围内，三叶青提取物对流感及仙台病毒有较强的抗病毒效果。</h3><h3><br></h3><h3>《南京中医药大学学报》曾公开报道三叶青提取物能够对乙肝病毒的DNA具有显著的抑制作用，即在病毒复制水平就能抑制病毒的合成，药物浓度越高，抑制作用越强。</h3> <p style="max-width: 100%;
