- 43 Downloads
A new sesquiterpene lactone, C15H22O4, which has been called artapshin (I) has been isolated fromArtemisia fragrans Willd. The acetylation of (I) led to its diacetate C19H26O6, mp 160–162°C (II). The saponification of (II) gave a dihydroxylactone C15H22O4, mp 118–120°C. A structure has been proposed from artapshin on the basis of its chemical and spectral (IR and NMR) characteristics.
