[Objective]The aim was to study isolation and purification technology of solanesol from discarded tobacco.[Method]The extraction,isolation and purification technology of solanesol from discarded tobacco were studied by adopting ultrasonic-assisted extraction technique and column chromatography.[Result]The optimum extraction conditions of solanesol from discarded tobacco were obtained through orthogonal experiments as follows:the u1trasonic power was 120 W;the extraction time was 60 min;the proportion of raw...
