Structure Elucidation of Prenyl- and Geranyl-Substituted Coumarins in <i>Gerbera piloselloides</i> by NMR Spectroscopy, Electronic Circular Dichroism Calculations, and Single Crystal X-ray Crystallography

Structure Elucidation of Prenyl- and Geranyl-Substituted Coumarins in <i>Gerbera piloselloides</i> by NMR Spectroscopy, Electronic Circular Dichroism Calculations, and Single Crystal X-ray Crystallography

Crude ethyl acetate extract of <i>Gerbera piloselloides</i> (L.) Cass. was investigated by dual high-resolution PTP1B/α-glucosidase inhibition profiling and LC-PDA-HRMS. This indicated the presence of a series of unprecedented prenyl- and geranyl-substituted coumarin derivatives correlat...
