Photophysical Chracterization of Galanthus elwesii Hook

Abstract

The investigation of photophysical properties of the Galanthus elwesii Hook different plant organs (root, leaf, flower and bulb) at different growing stages (start and after flowering, fruit ripening) has been carried out via UV-Vis spectrophotometry, fluorescence spectrometer and the cyclic voltammetry analysis. Polyphenol contents are a group of natural compounds for drug discovery. The correlation of their potential to act biological activite (depending on polyphenolic content) and their photophysical properties have been investigated. Fruit ripening and beginning of flowering stage were observed at highest emission values; beginning of the flowering bulb has highest fluorescence quantum yield. Fruit ripening and beginning of the flowering stages were observed at the highest emission values. The quantum yields were calculated and as a result, beginning of the flowering bulb stage showed the highest quantum yield value.
