Abstract
A new bioactive eremophilanolide, 1α-tigloyloxy-8βH,10βH-eremophil-7(11)-en-8α,12-olide (1), was isolated from Senecio poepigii and its structure was elucidated by spectral analysis. 1α-Angeloyloxy-8β-methoxy-10βH-eremophil-7(11)-en-8α,12-olide (2) was also isolated. Antifungal and insect antifeedant properties were evaluated.
