摘 要:目的对中药复方热毒宁注射液抗病毒活性成分进行研究。方法采用流感病毒致应激负荷小鼠模型进行热毒宁注射液抗病毒活性部位的筛选,综合应用各种现代色谱技术对活性部位进行分离和纯化,根据化合物的光谱数据和理化性质进行结构鉴定。采用检测流感病毒神经氨酸酶活性的方法,对分离得到的黄酮类化合物进行了体外抗甲型流感病毒(A/PR/8/34H1N1)的活性测试。结果热毒宁注射液经大孔吸附树脂95%乙醇洗脱部位为抗病毒活性部位,从中分离鉴定了20个化合物,分别鉴定为丁香酸(1)、阿魏酸(2)、苯甲酸(3)、咖啡酸(4)、对羟基苯甲醛(5)、香草醛(6)、4-羟基-3-甲氧基苯丙酸(7)、反式对羟基桂皮酸(8)、反式邻羟基桂皮酸(9)、反式桂皮酸(10)、7-羟基-6-甲氧基-香豆素(11)、7-羟基-6,8-二甲氧基-香豆素(12)、香豆素(13)、3-羟基-1,2-双(4-羟基-3-甲氧基苯基)-1-丙酮(14)、异鼠李素(15)、槲皮素(16)、木犀草素(17)、芦丁(18)、金丝桃苷(19)、木犀草素-7-O-β-D-吡喃葡萄糖苷(20);其中木犀草素对流感病毒的EC50值小于50μmol/L,选择指数(SI)值大于10,具有较强的抗甲型流感病毒活性。结论化合物1~20均为首次从热毒宁注射液中分离得到,木犀草素为热毒宁注射液抗病毒活性成分之一。Objective To study the antiviral constituents from the active fraction of Re-Du-Ning (RDN) Injection. Methods In this study, the active fraction of RDN Injection was screened by the mice model loaded with restraint stress infected with influenza virus. The investigation on this fraction led to the isolation and identification of compounds through various chromatographic techniques and spectroscopic methods. In addition, the in vitro activity on influenza virus A (A/PR/8/34 H1N 1) of the flavonoids was evaluated in vitro by the method for the detection of anti-influenza virus neuraminidase activity. Results Through the macroporous adsorption resin, 95% ethanol eluate of RDN Injection was proved to be the antivirus active fraction of RDN Injection. Twenty compounds were obtained and characterized as syringic acid (1), ferulic acid (2), benzoic acid (3), caffeic acid (4), p-hydroxy benzaldehyde (5), vanillin (6), 4-hydroxy-3-methoxy styrene acrylic acid (7), trans-p-hydroxy cinnamic acid (8), trans-o-hydroxy cinnamic acid (9), trans-cinnamic acid (10), 7-hydroxy-6-methoxy coumarin (11), 7-hydroxy-6, 8-dimethoxy coumarin (12), coumarin (13), 3-hydroxy-1, 2-his (4-hydroxy-3-methoxyphenyl)- 1-propanone (14), isorhamnetin (15), quercetin (16), luteolin (17), rutin (18), hyperoside (19), and luteolin-7-O-13-D-glucoside (20). Among them, luteolin exhibited the antivirus activity against Flu A virus. Conclusion All the isolated compounds are reported from RDN Injection for the first time, and luteolin exhibits the most potential activity against H1NI.
