МІЖФАЗОВИЙ РОЗПОДІЛ ДЕЯКИХ АЛКАЛОЇДІВ У СИСТЕМІ ВОДА-МІЦЕЛЯРНА ФАЗА TRITON X-100
Анотація
The employing of cloud point extraction (CPE) as a simple and effective alternative for recovery of alkaloids followed by quantitative analysis by HPLC, pH- titration or UV-vis. spectrometry is demonstrated. An aqueous surfactant solution containing 1-5% Triton X-100 was used for extraction of caffeine-benzoate, isonicotinic acid and quinidine. The dependences of recovery from pH, concentration of surfactant and alkaloids were obtained. Results show that the maximum recovery of alkaloids in optimal conditions is 48,6% for caffeine-benzoate, 76,9% for isonicotinic acid and 99,9% for quinidine.
