Unlocking the anti-herpetic properties of plants found in Egypt

This study was conducted by researchers from the National Research Centre in Egypt and the University of South Brittany – Campus Tohannic in France to evaluate the anti-herpetic activity of 25 different Egyptian plants in vitro. The results were published in the journal Food Science and Human Wellness.

  • The researchers used Vero cell lines to evaluate the antiviral activity of extracts obtained from different plants against Herpes Simplex Virus type 1 (HSV-1).
  • They found that extracts from only two plants, namely, Euphorbia coopire (Euphorbiaceae) and Morus alba (Moraceae) showed potent anti-herpetic activity. Six other extracts showed moderate inhibition.
  • They conducted a bioassay-monitored phytochemical exploration of the two plants and isolated pure flavonoid compounds from them.
  • They examined the antiviral activity of the isolated compounds and found that these seven pure compounds exhibited significant inhibition of HSV-1 viral activity:
    • 7-O-galloyl catechin
    • Gallic acid
    • Kaempferol 3-O-B-(6?-O-galloyl)-glucopyranoside
    • Quercetin 3-O-B-(6?-O-galloyl)-glucopyranoside
    • Curcumin
    • Quercetin
    • Kaempferol
  • Among the seven compounds, they identified gallic acid, 7-O-galloyl catechin, and curcumin as the compounds with the strongest antiviral activity.

Based on these results, the researchers concluded that gallic acid, 7-O-galloyl catechin, and curcumin could be potential therapeutic agents for the treatment of adenoviral infections.
