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. . | VNU Journal of Science Natural Sciences and Technology 26 2010 110-113 Obtaining Essential Oil and Shikimic Acid from Star Anise Fruit Illicium verum Hook Bui Quang Thuat Bui Thi Bich Ngoc Center for Oil Flavour and Food Additive Food Industries Research Institute 301 Nguyen Trai Hanoi Viet nam Received 11 March 2010 Abstract.

Keywords star anise fruit Illicium verum Hook shikimic acid essential oil 1. Introduction Star anise Illicium verum Hook as the name suggests is star-shaped native to southern China and northern part of Vietnam it is now introduced throughout the tropics and subtropical Eastern Asia. Dried star anise fruits have a essential oil content of 8 - 10 and a shikimic acid content of 5-7 1-3 which are the most valuable compositions of star anise plant. Essential oil from star anise fruits is traditionally obtained by steam distillation and shikimic acid is extracted from this fruit with alcohol methanol ethanol or water 4 5 . However there is only a few works researching on the method of obtaining simultaneously essential oil and shikimic acid from star anise fruit. We are therefore interested in researching Corresponding author.

Material and method Sample preparation Star anise Illicium verum Hook fruits were received from Lang son which is the largest material area in Vietnam. .
