Four new 2-phenoxychromone derivatives were isolated from Artemisiae Capillaris Herba (Japanese name, "Inchinko"茵〓蒿). Their structures were established on the basis of chemical and spectroscopic evidences as 2-(p-methoxyphenoxy)-6-methoxy-5,7-dihydroxychromone (4'-methylcapillarisin), 6,7-dimethoxy-2-(p-hydroxyphenoxy)-5-hydroxychromone (7-methylcapillarisin) 2-(p-methoxyphenoxy)-5,7-dihydroxychromone (6-demethoxy-4'-methylcapillarisin), and 2-(p-hydroxyphenoxy)-5,7-dihydroxychromone (6-demethoxycapillarisin), respectively. Four flavonoids, cirsilineol, cirsimaritin, genkwanin, and rhamnocitrin, were also isolated from this herb.
