Synthesis and structural characterization of β -cyclodextrin butenate.

β-cyclodextrin butenate was synthesized by using N, N'-Carbonyldiimidazole (CDI) activating reagent and 4-Dimethylaminopyridine (DMAP) as catalyst. The best preparation condition of β-CD butenate was described as below: reaction temperature was 25°C, concentration of 2-butenoic acid was 450 mmol/L, concentration of DMAP was 12.5 mmol/L and reaction time was 20 minutes and at this condition the yield of β-CD butenate was 0.

Thermally induced isomerization of linoleic acid and α-linolenic acid in Tratt seed oil.

seed oil is obtained from the seeds left following pressing of the juice from fruit. The total oil content of seed was around 9.30%.
