Polarographic determination of flavanoids (II)
In this work, polarographic reduction of the water- soluble flavanoids in the flower of the plant, Helichrysum graveolens, which is grown in Bursa, Uludağ Hotels Region, has been investigated on the Dropping Mercury Electrode (DME) in aqueous 30% ethyl alchohol. A single irreversible wave was observed in pH range 2.90- 10.11. Logarithmic analysis of the waves has been made and kinetic parameters (αn and kof,h) have been calculated by Kern’s and Koutecky’s methods. Based on the kinetic parameters, mechanism of the reduction process was proposed depending on pH.
