摘要：

Examination of a number of specimens of several X anthium species has disclosed the existence of chemical differences between species and between individual X. strumarium chemovars. Two new lactones, xanthanol and isoxanthanol, have been isolated and related to xanthinin and to ivalbin, a lactone from Iva species. The xanthinin–ivalbin and xanthumin–gafrinin series are differentiated in the stereochemistry of the lactone ring fusion. © 1969, American Chemical Society. All rights reserved.
