Summer 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%.

The methods for obtaining simultaneously essential oil and shikimic acid from star anise fruit (Illicium verum Hook) were investigated. From obtained results, we chose a simple and effective method for desired purpose. With this method, distillation of essential oil and extraction of shikimic acid were simultaneously carried out in the round bottom flask of the Clevenger apparatus. The yield of essential oil and shikimic acid were 9.5% and 5.6% (r.m), respectively as well as the quality of the products is very good. ...
