Secondary metabolite isolated from ramalina dumeticola and its application for silver nanoparticles production

Abstract

The aim of the study is to elucidate chemical compositions of the lichen Ramalina dumeticola and to evaluate the ability of the extract to produce silver nanoparticles. The sample was soaked in different polarities of solvent namely hexane, acetone, methanol and water. Isolation work on the acetone extract gave a despite which was identified as sekikaic acid (1). The structure was elucidated by spectroscopic methods. For the production of silver nanoparticles (AgNPs), metabolites from the acetone extract and water extract show potential as reducing agents for silver ions.
