ABSTRACT
AIM:
To discuss the technique for preparing high-purity solanesol from tobacco.METHODS:
The pre-treated tobacco leaves were extracted with mixed solvent of petroleum ether and ethanol,and saponified to obtain solanesol extract; The solanesol extract got through redissolution and dewaxing,then crystallized in the temperatare of -18 ℃; Finally purified by macroporous resin(YPR-Ⅱ,D-1300,HZ-816,HZ-802).RESULTS:
The ratio of mixed solvent of petroleum ether and ethanol was 1 ∶ 4,ratio of liquid to materials was 1 ∶ 12,solanesol purity was about 32% after saponification,then crystallization made the purity up to 63. 4% ,finally purified through macroporous resin,the solanesol purity reached above 93. 6%.CONCLUSION:
Through the general solvent extraction,saponification,crystallization and macroporous resin adsorption process,the solanesol purity of the product reaches higher than commonly expected values.
