Examples of the chromatograms of Se species in rice tissues extracted with protease XIV, as determined using anion exchange HPLC–UV-HG-AFS. Se species in rice tissues under (a) 10 μM SeNPs, (b) 30 μM SeNPs, (c) 10 μM selenite, and (d) 10 μM selenate treatment. 1 (unknown Se species 1); 2 (SeCys2, selenocystine); 3 (MeSeCys, Se-methyl-selenocysteine); 4 [Se(IV), selenite]; 5 (SeMet, selenomethionine); 6 (unknown Se species 2); 7 (unknown Se species 3); 8 [Se(VI), selenate]
