Preparation and Characterization of Hydroxypropyl-.BETA.-Cyclodextrin Inclusion Complex of Eugenol: Differential Pulse Voltammetry and 1H-NMR

Preparation and characterization of β-cyclodextrin inclusion complexes as a tool of a controlled antimicrobial release in whey protein edible films

“…For eugenol Dd free-complexed H-9 and H-9 0 were 0.022 and 0.123, respectively. These Dd free-complexed results agree with previous studies (Garg et al, 2010;Locci, Lai, Piras, Marongiu, & Lai, 2004;Mulinacci et al, 1996) even when different complex preparation and dried methods were used, and confirm that there are interactions between carvacrol and eugenol aromatic rings protons, and protons in the hydrophobic cavity of b-CD. This data suggests that the initial molar ratio (1:1) used during complex preparation was not maintained.…”

“…These differences, the slight movement of bands, suggest hosteguest interaction of the eOH group of carvacrol with the CeOeC group of the b-CD. Such differences in FTeIR spectrum have been previously reported for cyclodextrin complexes obtained by different preparation methods (Garg et al, 2010;Kayaci & Uyar, 2011). Similar results were observed with eugenol and b-CD inclusion complex (data not shown).…”

“…For the purpose of controlling this antimicrobial activity in a specific time, the use of cyclodextrins may encourage molecular interactions with various types of molecules such as, terpenes and phenols, intervening in their release (Garg, Gupta, Prakash, & Singh, 2010;Marques, 2010;Mulinacci, Melani, Vincieri, Mazzi, & Romani, 1996;Reineccius, 2009;Reineccius, Reineccius, & Peppard, 2002;Reineccius, Reineccius, & Peppard, 2003;Szejtli, Szente, & Bankyelod, 1979). In particular, small molecules can form inclusion complexes with cyclodextrins, especially apolar molecules, which are well-suited for inclusion in the hydrophobic cavity CDs.…”

Targeting of Eugenol-Loaded Solid Lipid Nanoparticles to The Epidermal Layer of Human Skin

“…Therefore, the inclusion complex of eugenol with hydroxypropyl-b-cyclodextrin (Hp-b-CD) was prepared and incorporated into hydrogel to overcome these problems and used as a reference in the study to compare the permeation and retention data obtained from EG-SLNenriched hydrogels. The eugenol-Hp-b-CD complex in hydrogel was previously prepared and characterized [46].…”

An electrochemical study in aqueous solutions on the binding of dopamine to a sulfonated cyclodextrin host

“…This means that the formation of the inclusion complex can be studied using electrochemical techniques. This electrochemical approach is used frequently to study the formation of an inclusion complex [14][15][16][17][18]. For example, Strelets et al [19] have studied the formation of an inclusion complex between ferrocene and ␤-CD using cyclic voltammetry by monitoring the oxidation of ferrocene in the absence and presence of the neutral ␤-CD.…”
