This study was carried out to compare the essential oil and its composition, and estragol content at different growth stages in the local collections of A. rugosa. Estragol was the major constituent in essential oil of all collections tested. Estragol content in essential oil was $82.3{\sim}89.1%$ in leaves, $81.1{\sim}89.2%$ in inflorescence, $72.0{\sim}45.2%$ in stem and there was no significant difference among nine local colletions. At full bloom stage, essential oil content was significantly higher than other growth stages and the highest content of estragol in essential oil was appeared at this stage. Especially, the content of essential oil in the inflorescence of Mokpo collection was 3.3%, which was the highest among the collections. Mokpo and Jindo collections produced much more essential oil and estragol than the other collections both at full bloom and ripening stages.
