Dibromo- and tetrabromostearic acids in the seed oil ofEremostachys moluccelloides

Mass spectra of methyl esters of brominated fatty acids and their presence in soft drinks and cocktail syrups

“…(d)). In agreement with Gusakova and Umarov, the base peak appeared at m/z 291 ([M−Br−3HBr] + ). This non‐brominated fragment ion was accompanied by m/z 293 (35%), which represents [M−3Br−HBr] + .…”

“…Gusakova and Umarov isolated the naturally produced Br 2 ‐18:0 from seed oil and presented characteristic ions of the methyl ester obtained by direct inlet mass spectrometry. Compared to our GC/MS spectra they obtained higher abundance in the high mass range, with m/z 295 being the base peak . In contrast, the characteristic low‐mass fragment ions were not detected in their study .…”

“…Compared to our GC/MS spectra they obtained higher abundance in the high mass range, with m/z 295 being the base peak . In contrast, the characteristic low‐mass fragment ions were not detected in their study . These low mass fragment ions also included m/z 81/83 (Supplementary Table S1, Supporting Information).…”

“…While gas chromatography with mass spectrometry (GC/MS) appears to be well‐suited for the determination of brominated fatty acids and for the determination of BVO compositions, this technique has rarely been reported in the literature . Moreover, GC electron ionization (EI) MS spectra of brominated fatty acids were available only in the form of the methyl esters of Br 2 ‐18:0 and Br 4 ‐18:0 …”

Essential Oil Composition of Two Species ofEremostachysfrom Iran (E. adenanthaJaub. et Spach andE. macrophyllaMontbr. et Auch.)

“…The presence of phenylethanoid glycosides (4) and ferulic acid derivatives (5) with promising antioxidant activities, furanolabdane diterpene glycosides (6) and iridoid glycosides (7) have been confirmed in this plant. The seed oil of several species of Eremostachys have been subjected to phytochemical investigations (8)(9)(10)(11). Monoterpene glycosides have been found in E. fetissovii (12) and the occurrence of a distinctly different flavonoid aglycone and glycone have been reported from E. angreni M.Pop and E. lehmanniana Bge (13).…”
