β-cyclodextrin

This study explores the effectiveness of β-cyclodextrin (β-CD) as a carrier for essential oils (EOs), specifically d-limonene, and eugenol, within biodegradable delivery systems. Inclusion complexes were prepared via coprecipitation and analyzed using Fourier-transform infrared spectroscopy. FTIR analysis confirmed the encapsulation, indicated by the shift in the O-H stretching vibrations of β-CD and a reduction in the intensity of the C-H stretching vibrations of d-limonene, which suggests successful molecular inclusion.

In this paper, the porous structure of three types of β-cyclodextrin (β-CD) carbons was synthesized and investigated. The first carbon was obtained from pure β-CD, the second carbon was synthesized from β-CD using the KOH activator, and the third carbon was synthesized from pure β-CD with additional ultrasonic treatment in the non-cavitation mode at the last stage. It was found that the carbon from pure β-CD has a micromesoporous structure with a small specific surface area (~35 m2/g).
