Green onion

“Electrospray ionization ion trap mass spectrometry (ESI-ITMS) confirmed the presence of γ-glutamyl-Se-methylselenocysteine in green onions as has been reported in other onion types.”

γ-glutamyl-Se-methylselenocysteine → present in → green onions (Allium fistulosum)

“Matching the chromatographic retention times with commercially available standards provided evidence for the presence of Se-cystine, methylselenocysteine, Se-methionine, and inorganic selenium.”

inorganic selenium → present in → green onions (Allium fistulosum)

“Matching the chromatographic retention times with commercially available standards provided evidence for the presence of Se-cystine, methylselenocysteine, Se-methionine, and inorganic selenium.”

Se-methionine → present in → green onions (Allium fistulosum)

“The plant extract obtained using sodium hydroxide (0.1 mol l−1) analyzed by SEC (CAPS 10 mmol l−1, pH 10.0) with ICP-MS detection showed the incorporation of selenium in both high (∼12 kDa) and low molecular weight (0.36–2 kDa) fractions.”

selenium → incorporated in → green onions (Allium fistulosum)

“Matching the chromatographic retention times with commercially available standards provided evidence for the presence of Se-cystine, methylselenocysteine, Se-methionine, and inorganic selenium.”

Se-cystine → present in → green onions (Allium fistulosum)
