Phase Solubility Studies. The determination of the phase solubility diagram is a widely accepted method for evaluation of the effect of cyclodextrin complexation on the drug solubility. The phase solubility studies were performed by the method reported by Higuchi and Connors . Increasing concentrations of MβCD (0–0.23 M) or …Solubility studies. The phase-solubility diagram corresponding to DPS:βCD system is illustrated in Fig. 5. It was performed according to the method reported by of Higuchi and Connors in order to determine the stability constant of the suggested complex and evaluate its stoichiometry. Measurements were made at 291 nm, which corresponds to the ...According to Higuchi and Connors’ theory, [17] the phase-solubility relationships between PD and β- and γ-CDs are classified as typical A L-type, ... according to the method reported by Higuchi and Connors (1965). ...

Phase solubility studies. The impact of the presence of BCD on the aqueous solubility of propolis extract was measured at different temperatures. Phase solubility studies were carried out according to the method described by Higuchi and Connors (1965). Saturated solution of BCD (15 mM) was prepared, heated at 50 °C and shaken until complete ...Phase solubility studies The phase solubility studies were carried out according to the method of Higuchi and Connors (Jansook et al. 2018 ; Higuchi & Connors 1965 ). Briefly, an excess of KME was added to 200 μL aqueous solutions of different HP-β-CD concentrations (1, 2, 4, 6, 8, and 10 mM).May 1, 2022 · All experiments were repeated three times. According to the linear part of the phase solubility curve, the stability constant (Kc) was calculated using the Higuchi-Connors equation. (1) K c = S l o p e S 0 × (1-S l o p e) S 0: the solubility of NAR without β-CD. The solubilizing efficiency of β-CD was evaluated by the complexation efficiency ... Phase solubility studies.
