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.
