摘要：

The isolation of four new germacranolides from Eupatorium serotinum Michx. is reported. Structures and stereochemistry of 1a, b and 2a were established by NMR spectrometry and chemical interconversions. The structure of euserotin (3), an unusual germacradienecarboxylic acid, was elucidated by X-ray crystallography. The flavones pectolinarigenin and hispidulin were also found. © 1979, American Chemical Society. All rights reserved.
