β-cyclodextrin

Іmpact of morphology on D-limonene payload and diffusion in biodegradable prolonged release films

In this study, D-limonene is integrated into films made with different ratios of gelatin to β-CD. The FTIR, vacuum liquid absorption method and gravimetric analysis were used to assess porosity and swelling behavior. Inclusion and retention were detected by FTIR analysis in distinctive peaks at 870–890 cm-1. Films with a 3:1 gelatin to β-CD ratio had a higher D-limonene payload. Porosity and swelling are enhanced with increasing β-CD content.

ANALYSIS OF LIMONENE AND EUGENOL INTEGRATION INTO THE FIXATIVE AS A CHARACTERISTIC OF A SUSTAINED-RELEASE COMPLEX

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.

THE INVESTIGATION OF THE POROUS STRUCTURE OF CARBON SORBENTS BASED ON β-CYCLODEXTRIN FOR USE IN ENVIRONMENTAL PROTECTION TECHNOLOGIES

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).
