Abstract
The partition coefficient of Azadirachta Indica A. Juss. (neem) seed oil (N SO) in water + hexane was calculated by measuring the amount of NSO concent ration in hexane by a UV spectrophotometric method at (298.15, 303.15, 308. 15, and 313.15) K. The partition coefficients of NSO increased with an incr easing amount of NSO, which indicates a hydrophobic interaction of NSO in t he organic phase. Addition of cosolvent (methanol) or nonionic surfactant ( polysorbate-80) to the water + hexane mixture decreased the partition coeff icient of NSO in the temperature interval studied.
