Antiviral Activity of Vitis vinifera Leaf Extract against SARS-CoV-2 and HSV-1.

Vine leaves contain bioactive compounds with antiviral properties against human pathogens. Researchers evaluated the phenolic composition and antiviral activity of leaf extract against Herpes simplex virus type 1 (HSV-1) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). HPLC-MS/MS analysis identified 40 phenolic compounds in the extract, including quercetin derivatives, luteolin, kaempferol, and apigenin. The extract inhibited both viruses at a low concentration of 10 μg/mL. These findings suggest natural extracts could be used in antiviral drugs and future vaccines.
