Artemisia iwayomogi (Compositae), a perennial mugwort, is native to Korea and widely distributed in Japan, Russia, and China. A. iwayomogi and A. capillaris are similar in morphology and pharmacological activity and have been used for the same medicinal purposes in Korea. While various ingredients such as coumarins and flavonoids and their activity studies have been reported for A. capillaris, few studies have been conducted on the pharmacologically active components of A. iwayomogi. In Korea, A. capillaris is not economical because only young leaves are used as a medicinal material. Because of this, A. iwayomogi is frequently used in Korea, indicating the need to study its pharmacologically active components. Therefore, a phytochemical study was initiated to isolate active compounds from the aerial parts of A. iwayomogi. Finally, four coumarins, umbelliferone (1), esculetin (2), grevillone (3), and scoparone (4) were isolated for the first time from the aerial parts of A. iwayomogi in this study.
