Table IV.

Slope, Apparent Stability Constant (K 1:1) and Correlation Coefficient (R 2) Determined from the Δ8-THC: HPβCD, Δ8-THC: RMβCD and Δ8-THC: SβCD Aqueous Phase-Solubility Diagrams

Cyclodextrins Slope × 106 K 1:1 (M−1) R 2
HPΒCD 7.36 11,555 0.997
RMΒCD 7.76 12,200 0.994
SΒCD 19.20 31,000 0.998

The solubility of Δ8-THC in the absences of CD (S0) was found to be 0.64 ± 0.01 × 10−6 mM
