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,
