Influence of Temperature on Free Radical Generation in Propolis-Containing Ointments
The influence of microwave power () on (a, c, e, and g) amplitudes () and (b, d, f, and h) linewidths () of the EPR spectra of the ointment containing 5% of propolis thermally treated at temperatures 30°C (a, b), 40°C (c, d), 50°C (e, f), and 60°C (g, h). : microwave power used during the measurement of the EPR spectra; : total microwave power produced by klystron (70 mW).
