摘    要:目的:对板蓝根药材中提取的10个化学部位进行体外抗单纯疱疹病毒(HSV)活性研究,确定板蓝根抗病毒的有效部位。方法:利用溶剂法和色谱法从板蓝根中提取分离出10个粗提和精制部位,用MTT法检测这10个部位体外对HSV-Ⅰ及HSV-Ⅱ型病毒的抑制作用,以病毒抑制率和治疗指数(TI)为评价指标,比较各化学部位体外抗病毒的效果。结果:水提大孔树脂吸附的10%、50%醇洗部位(Ⅷ、Ⅹ)作用最强,对HSV-Ⅰ型病毒的抑制率为分别为53.21%、56.28%,接近阳性对照药阿昔洛韦(62.55%),其TI分别为4.61、18.62。结论:板蓝根不同化学部位的抗病毒作用强度有较大差异。

Abstract:OBJECTIVE:To study the activity of 10 chemical parts extracted from Isatis indigotica against herpes simplex virus(HSV) in vitro and to determine the antiviral active parts.METHODS: 10 crude fractions and refined portions were extracted from Isatis indigotica using solvent isolation and absorption chromatography.Their inhibitory effects against HSV- Ⅰ and HSV- Ⅱ were determined by MTT using virus inhibition ratio and therapeutic index(TI) as appraisal targets to compare the antiviral effects among all the chemical parts.RESULTS: The parts(Ⅷ, Ⅹ ) with EtOH(10% and 50% in concentration) elution via macroporous resin absorption showed the most potent activities, whose inhibitory rates against HSV- Ⅰ were 53.21% and 56.28% respectively, similar the action of its positive control acyclovir(62.55% ), and their TI were 4.61 and 18.62 respectively.CONCLUSION: There were significant differences in the antiviral activity among all the chemical parts extracted from Isatis indigotica.
Keywords:Isatis indigotica  Herpes simplex virus(HSV)  Antivirus  Active parts
