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 spectrophotometre, 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 as biologically activity (depend on polyphenolic
content)  and photophysical properties have been investigated. Fruit
ripening and beginning of flowering stage was observed highest emision value,
beginning of flowering bulb is highest florescence quantum yield. The quantum
yields were calculated and as a result, the highest value belongs to after
flowering leaf and bulb.
