The objective of this study was simultaneous extraction and encapsulation of cornelian cherry active principles. As an encapsulating agent, β-cyclodextrin (β-CD) was used to enhance the ultrasound-assisted extraction of cornelian cherry polyphenols and iridoids. Lyophilized cornelian cherry fruit was extracted by four different solvents: pure water, 50% aqueous ethanol (conventional system), 1.5% β-CD water solution and 1.5% β-CD aqueous ethanol solution. The highest enhancement of the extraction efficiency was observed for flavonoids and anthocyanins, especially for cyaniding 3-galactoside and pelargonidin 3-galactoside.

The encapsulation efficiency of cornelian cherry polyphenols in β-CD was 65.62%. Due to the polyphenol encapsulation within β-CD, the extract showed better solubility in water, higher antioxidant power (for 40.61%), and the release of anthocyanins from the dried powder was prolonged for 50% in the first 2 h making it suitable for diverse applications in food and pharmaceutical industries.

Abstract

The objective of this study was simultaneous extraction and encapsulation of cornelian cherry active principles. As an encapsulating agent, β-cyclodextrin (β-CD) was used to enhance the ultrasound-assisted extraction of cornelian cherry polyphenols and iridoids. Lyophilized cornelian cherry fruit was extracted by four different solvents: pure water, 50% aqueous ethanol (conventional system), 1.5% β-CD water solution and 1.5% β-CD aqueous ethanol solution. The highest enhancement of the extraction efficiency was observed for flavonoids and anthocyanins, especially for cyaniding 3-galactoside and pelargonidin 3-galactoside. Water-ethanolic extract was used to form inclusion complexes between β-CD and cornelian cherry bioactives in the solid form. The encapsulation efficiency of cornelian cherry polyphenols in β-CD was 65.62%. Due to the polyphenol encapsulation within β-CD, the extract showed better solubility in water, higher antioxidant power (for 40.61%), and the release of anthocyanins from the dried powder was prolonged for 50% in the first 2 h making it suitable for diverse applications in food and pharmaceutical industries.
