Antioxidant, Antibacterial, and Antiviral Activity of Commercial Products of Piper guineense and Piper borbonense

---

Abstract

This study aims to analyze the chemical composition of commercial products derived from Piper guineense and Piper borbonense, and to evaluate their fruit extracts' antioxidant capacity and antibacterial and antiviral potential. The genus Piper has a long history of use in traditional medicine and is known for its diverse biological activities that validate its traditional applications. In these experiments, P. guineense and P. borbonense were identified as sources of natural antioxidants, offering potential protection against diseases associated with reactive oxygen species. Both species also demonstrated significant antibacterial activity against gram-positive Bacillus subtilis, highlighting their possible role in food preservation. Notably, P. borbonense exhibited antiviral activity against SARS-CoV-2PsV, with a high therapeutic index, suggesting its potential as a therapeutic agent for treating COVID-19.
