The genus Ajania, belonging to the family Asteraceae, includes around 28 species that are distributed over central and south Asia, China, and Japan . Most of them are widespread in the northwest of China. Some species of the genus have long been used as Chinese traditional folk medicines for the treatment of intestinal ulcers, bronchitis, lung diseases, and rheumatism [2, 3].
Ajania tenuifolia is mainly distributed in high plateaus of the northwest of China. Some sesquiterpenoids, flavonoids, triterpenoids, lignans, penylpropanoids, phenolics, and acetylenes have been isolated from some species of Ajania plants [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], while the chemical constituents of this species have not been investigated so far. As a part of our work on bioactive metabolites from the plant kingdom, the chemical constituents of A. tenuifolia were studied for the first time, and 29 compounds were isolated and characterized.
