Zusammenfassung:	A cacalolide derivative named 4α-[2′-hydroxymethylacryloxy]-1β-hydroxy-14-(5-6)abeo eremophilan-12,8-olide and a shikimic acid derivative named (3′ E)-(1α)-3-hydroxymethyl-4β, 5α-dimethoxycyclohex-2-enyloctadec-3′-enoate together with three known compounds were isolated from Senecio burtonii. A cacalolide derivative named 4α-[2′-hydroxymethylacryloxy]-1β-hydroxy-14-(5 → 6) abeo eremophilan-12,8-olide and a shikimic acid derivative named (3′ E)-(1α)-3-hydroxymethyl-4β,5α-dimethoxycyclohex-2-enyloctadec-3′-enoate along with three known compounds, octacosan-1-ol, 3β-hydroxyolean-12-en-28-oic acid and 3β-acetoxyolean-12-en-28-oic acid were isolated from Senecio burtonii. Their structures and relative configurations were established on the basis of spectroscopic analysis.
