selleck chemical lower than the amplitude of EPR signal of DPPH in ethyl alcohol solution, before adding of the tested herb (Table 1). purpureae irradiated by UV longer than 10 min 20–110 min (Table 1). This correlation is presented in Fig. 3. From Fig. 3a, it is clearly visible that all the relative amplitudes (A/A DPPH) of EPR lines with the solution containing the tested herb are lower than one (Fig. 3a), so E. purpureae is antioxidant. UV irradiation negatively affects antioxidant properties of E. purpureae (Fig. 3a, b). In Fig. 3b, the total amplitudes (A) of DPPH interacting with nonirradiated and
UV-irradiated E. purpureae are compared. The total amplitudes (A) are also lower for the UV-irradiated samples. Fig. 3 Amplitudes of EPR spectra of DPPH in ethyl alcohol solution, and DPPH interacting with nonirradiated and UV-irradiated E. purpureae in ethyl alcohol solution. The relative amplitudes A/ADPPH and the total amplitudes A are shown in Fig. 3a, b, respectively. A/ADPPH is the amplitude of EPR line of DPPH with the tested many sample in alcohol solution divided by amplitude of EPR line of the reference—DPPH in ethyl alcohol solution. The total amplitude A is the amplitude of EPR line measured for DPPH in ethyl alcohol solution. The times (t) of UV irradiation of the sample are in the range of 10–110 min The EPR spectra of DPPH in ethyl alcohol solution with E. purpureae were nonsymmetrical with the parameters of A 1/A 2 and B 1/B 2 which differ from 1, and the parameters of A 1 − A 2 and B 1 − B 2 differ from 0 (Table 1). It indicates that the major magnetic interactions exist in the tested samples. The parameters of lineshape of EPR spectrum of DPPH (A 1/A 2, B 1/B 2, A 1 − A 2, and B 1 − B 2) changed with the time of UV irradiation of E. purpureae (Table 1). The linewidths (ΔB pp) of EPR spectra of DPPH in ethyl alcohol solution both for nonirradiated and UV-irradiated E. purpureae had the high values (Table 1; Fig. 4). The linewidths (ΔB pp) changed with time of UV irradiation of the herbs.
