摘　　要：Two new eremophilenolides, 1β-hydroxy-2β-methylsenecioyloxyeremophil-7 （11）-en- 8β （12）-olide （1）, 1β-hydroxy-2β-methylsenecioyloxy-8α-methoxyeremophil-7 （11）-en-8β （12）- olide （2）, were isolated from the roots of Cacalia pilgeriana. Their structures were elucidated by spectroscopic methods and X-ray diffraction analysis.Two new eremophilenolides, 1β-hydroxy-2β-methylsenecioyloxyeremophil-7 （11）-en- 8β （12）-olide （1）, 1β-hydroxy-2β-methylsenecioyloxy-8α-methoxyeremophil-7 （11）-en-8β （12）- olide （2）, were isolated from the roots of Cacalia pilgeriana.
