摘要
目的 :研究板蓝根和大青叶抗甲型流感病毒作用。 方法 :选用鸡胚法分别考察各 15个种质的板蓝根和大青叶对甲型流感病毒 (A1京防 86 - 1)的抑制作用。 结果 :血凝滴度实验表明 ,在对甲型流感病毒的直接作用、治疗作用和预防作用 3方面大多数板蓝根和大青叶有效 ,但各种质药材样品抗病毒活性的有无及强度有明显差异。 结论 :在保证药材来源可靠的前提下 ,证明了板蓝根和大青叶确具抗病毒作用 ,并为药材种质的优选提供了一定的依据。
Objective: To investigate the antiviral action of traditional Chinese medicine Radix Isatidis and Folium Isatidis . Methods: Influenza A virus was used to infect chicken embryo in vitro , the antiviral action of the drug samples from 15 different germplasm were studied. Results: According to hemagglutination titer, it was proved that most of Radix Isatidis and Folium Isatidis were effective to influenza A virus in 3 aspects: direct, therapeutic and preventive action. Moreover, the antiviral activity of crude drugs from different germplasm varied obviously. Conclusion: On the base of the high quality of crude drugs, we clarify the fact that Radix Isatidis and Folium Isatidis surely have the antiviral action, and preliminarily offer a scientific foundation for the choice of first rate germplasm.
