Figure 6

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).
