Effect of the extract of Annona muricata and Petunia nyctaginiflora on Herpes simplex virus

Abstract

Annona muricata (Annonaceae) and Petunia nyctaginiflora (Solanaceae) were screened for their activity against Herpes simplex virus-1 (HSV-1) and clinical isolate (obtained from the human keratitis lesion). We have looked at the ability of extract(s) to inhibit the cytopathic effect of HSV-1 on vero cells as indicative of anti-HSV-1 potential. The minimum inhibitory concentration of ethanolic extract of A. muricata and aqueous extract of P. nyctaginiflora was found to be 1 mg/ml.
