Scholarcy highlights

  • Corncobs are an important byproduct of the sweet corn processing industry in Egypt, where they represent about 15% of the total corn production and the total volume of this by-product generated from the total volume of corn was estimated to be 54,424 ton in 2008
  • 6β-Hydroxycampest-4-en-3-one was identified by 1H-NMR, 13C-NMR and LC-MS. This compound has never been isolated from corncobs or from any members of the family Poaceae
  • Eight compounds have been isolated from corncobs
  • They are classified as two phenylpropanoids, two flavonoids and four plant sterols
  • Fraction A3 was purified by rechromatography on a silica gel column and eluted with ethyl acetate in petroleum ether followed by further purification on a cartridge of reversed phase silica
  • These findings suggest corncobs as as potential source of interesting phytochemicals
