ABSTRACTSummer anise star collected from Lang Son in 2008 was studied. The material was characterized by the essential oil content of 8,75%, moisture content of 13,2%, acid index of 4.5 mg KOH/g, ester index of 254.17 mg KOH/g and the relative density of 0,981. The procedures of essential oil distillation and trans-anethol isolation have been studied based on the properties of anise material. The yield of proposed procedure reached 76,4 % and the purity of anethol isolated was 96,83%.
