EPR signals of PSII membrane particles in the absence and presence of the lipophilic fraction of M. spicatum extract

EPR Signal	Control	+ Lipophilic Fraction
S2 multiline (S2 state of the Mn Cluster)	+	+
g = 1.9 and g = 1.82 of the QA−-Fe signal	+	+
g = 1.82 in the presence of formate	+	+
g = 1.98 in the presence of cyanide	+	+
Fe3+ signal after addition of 5 mm ferricyanide	+	–

The amount of extract used in the experiments was equivalent to 190 μg TAE mL⁻¹.
