betadex and camphene

This study's primary purpose was to develop a new technique to stabilize high value-added bioactive volatile compounds present in essential oils to ensure their usability as chemical raw materials with enhanced stability. Selective isolation and encapsulation of various volatile compounds by changing the electrospraying process parameter, including voltage, flow rate, and β-Cyclodextrin concentration, were attributed to the formation of inclusion complexes between β-cyclodextrin and volatile compounds. Investigations regarding the effects of independent process variables on simultaneous isolation and selective encapsulation of volatile compounds during electrospraying of β-cyclodextrins were carried out mainly with TLC analyses. The TLC analyses were confirmed with GC, GC-MS, and

The separation of isomeric monoterpenes, camphene and fenchene by complexation with β-cyclodextrin is presented. Both of the monoterpenes form complexes with β-cyclodextrin (as shown by both gas chromatography and (1)H NMR) with similar stability constants nevertheless it is possible to separate them by re-crystallization. The crystal structure of β-cyclodextrin with fenchene was also studied by X-ray diffraction.
