Analysis of the Chemical Profile of the Essential Oil from Leaves and Cones of Four Varieties of Humulus lupulus Cultivated in a Subtropical Climate Under Edaphoclimatic Conditions

Cultivating Humulus lupulus L. under subtropical conditions is challenging because hops are adapted to temperate climates, where environmental factors influence plant development and secondary metabolism. This study evaluated the essential oil yield and chemical composition of co...

Green synthesis of gold nanoparticles from Pfaffia glomerata extracts for enhanced electrode modification and antimicrobial applications

Gold nanoparticles (AuNPs) are widely used in pharmaceuticals, diagnostics, textiles, and energy. Plant extracts have become a promising green alternative for AuNP synthesis. Pfaffia glomerata (Brazilian ginseng) contains phenolics and saponins that serve as reducing and stabiliz...
