A recent study in Argentina, led by Biochemistry student Silvana Torrico at the Universidad Nacional del Nordeste (UNNE), is exploring the antimicrobial properties of three Cymbopogon species, commonly known as citronella. The research aims to provide scientific validation for the medicinal uses of these plants.
Torrico's project, supported by a grant from UNNE, focuses on Cymbopogon citratus (lemongrass), C. winterianus, and C. nardus (both citronella). Researchers will analyze the phytochemical composition of essential oils and extracts from these species collected in the region, and verify their antimicrobial and antioxidant properties using in vitro techniques.
This research is particularly relevant given the World Health Organization's (WHO) declaration of antimicrobial resistance as a major global health threat. The study seeks to standardize methods for obtaining and preserving essential oils and extracts, potentially leading to the development of new therapeutic agents. The findings will contribute to the understanding of medicinal flora in northeastern Argentina.
