Volatile constituents from Romanesco cauliflower

Sulphur-containing compounds in the essential oil of the root ofFerula persica Willd. var.persica

“…d Only identified by mass spectra. [11][12][13] The RRI values were similar to the ones reported in References 11-13.…”

Chemical composition of the volatile extracts fromBrassica oleracea L. var.botrytis ‘Romanesco’ cauliflower seeds

“…Few studies are reported on the chemical composition of volatile fractions of this raw material. [8][9][10] The compounds identified in the extract, and their importance, are described: dimethyl disulfide, hex-3(Z )-enol and dimethyl trisulfide have been reported as main volatile constituents in cooked florets. 10 To our knowledge, no chemical composition of volatile oils from the seeds of Romanesco cauliflower has been reported.…”

“…Plants produce and emit a number of gases (e.g., oxygen, carbondioxide, hydrogen, etc. ), volatile organic compounds (e.g., isoprenes, terpenes, alkanes, alkenes, aldehydes, esters, carbonyls, and acids), and volatile, sulfur-containing compounds (e.g., sulfides, polysulfides, thiols, and isothiocyanates) (Penuelas and Llusia, 2003;Valette et al 2003). The volatile compounds, collectively referred to as aroma or emissions, might indirectly reflect cellular metabolic activity and interactions with the environment.…”
