A new component of Artemisia fragrans

A new component C₁₅H₂₂O₃, has been isolated from the epigeal part ofArtemisia fragrans. On the basis of chemical transformations and spectral characteristics it has been established that it has the structure of 1α-hydroxy-5,7αH,6,11βH-eudesm-3,4-en-6,12-olide (I). V. L.
