女贞苷、 野漆树苷、 金丝桃苷组合物及其制备药物用途 技术领域
本发明涉及一种女贞苷、 野漆树苷、 金丝桃苷组合物及其制备药物用途。 背景技术
目前流行性感冒病毒日益严重,并且流行性感冒病毒与呼吸道疾病及引起的 全身性疾病密切相关, 我国是流感高发国家之一, 不但人口众多, 而且生活习惯 也有利于流感病毒的转播, 每年人平均发病次数达到 0.3~0.7次不等, 重点人群 达到 2~4次。流感对人类存在严重威胁, 尤其是新发品种流感病毒, 其不但引起 继发性其它微生物感染, 而且会直接导致器官破坏和变态反应致人死亡。但目前 并没有有效的治疗流行性感冒病毒及其疾病(流感)的方法和治疗手段, 如针对 临床症状进行炎症反应治疗, 治标不治本。 目前最常见的预防和治疗流行性感冒 病毒的方法是使用流感病毒疫苗接种,非特异性抗病毒中药或西药磷酸奥司他韦 (达菲) -神经氨酸酶抑制剂。然而流感病毒疫苗预防接种弊端在于接种人群有选择 性, 不是人人可以接种。此外, 流感病毒疫苗保护率不高, 保护时间也较短(3~6 个月)。 目前大多数非特异性抗病毒中药虽然宣称有抗病毒作用, 但是并非针对 流感病毒, 且抗病毒作用机理不清楚。 在我们以往研究的许多种治疗外感风寒, 西医所认为的感冒的中药组方并没有直接抗流感病毒的作用。简单的说, 不是所 有的治疗感冒的中药组方都有明确的抑制流感病毒的作用。 西药"磷酸奥司他韦 (达菲, (3R, 4R, 5S ) - 4 - 乙酰胺—5 - 氨基 - 3 ( 1-丙氧乙酯) - 1 - 环己烯 - 1 羧酸乙酯磷酸盐)"是神经氨酸酶抑制剂, 对流感病毒进入细胞有特异性抑制作 用, 但是不仅价格昂贵, 而且有一些患者服用后出现呕吐、 恶心、 失眠、 头痛、 腹痛、 腹泻、 头晕、 疲劳、 鼻塞、 咽痛和咳嗽等副反应。 达菲是在体内被位于肝 脏和肠道的酯酶转化为活性代谢产物而起着抑制神经氨酸酶作用,如果患者肝脏 和肠道器官功能不正常也将影响其药效。 此外, 肾功能不全患者也要慎用。
传统的中医学认山香圆叶具有清热解毒, 利咽消肿, 活血止痛。用于乳蛾喉 痹, 咽喉肿痛, 疮疡肿毒, 跌扑伤痛。 女贞苷、 野漆树苷、 金丝桃苷是山香圆叶 的主要成分之一。 女贞子功能为滋补肝肾, 明目乌发。 主要用于眩晕耳鸣, 腰膝 酸软, 须发早白, 目暗不明, 近年来多用于治疗慢性气管炎、 肝炎、 高血脂症、 糖尿病、 更年期综合征、 不孕症、 动脉粥样硬化等, 女贞苷是女贞子的主要成分 之一。 化橘红具有散寒, 燥湿, 利气, 消痰。 用于风寒咳嗽, 喉痒痰多, 食积伤 酒, 呕恶痞闷; 野漆树苷是化橘红的主要成分之一。 贯叶金丝桃具有舒肝解郁, 清热利湿, 消肿止痛。 用于情志不畅, 气滞郁闷, 关节肿痛, 小便不利。 金丝桃 苷是贯叶金丝桃的主要成分之一, 金丝桃苷对心肌缺血再灌注, 脑缺血再灌注, 脑梗塞都显示良好的保护作用, 还具有镇痛, 抗氧化, 保护心肌、 肝脏作用。 但 并未发现山香圆叶及其所含的女贞苷、野漆树苷和金丝桃苷、女贞子及其所含的 女贞苷、化橘红及其所含的野漆树苷、贯叶金丝桃及其所含的金丝桃苷具有抑制 流感病毒感染、 复制的作用, 也未发现其具有抑制神经氨酸酶的作用。 发明内容
