Abstract

Two new sesquiterpene lactones: 8α-(4′-acetoxymethacryloyloxy)-3α,9β-dihydroxy-1(10)E,4Z,11(13)-germacratrien-12,6α-olide (1) and 8α-(2′E)-(2′-acetoxymethyl-2′-butenoyloxy)-3α,9β-dihydroxy-1(10)E,4Z,11(13)-germacratrien-12,6αolide (2), together with the known zoapatanolide A were isolated from the aerial parts of Montanoa tomentosa Cerv. in La Llave et Lex ssp. microcephala (Sch. Bip. In K. Koch) V.A. Funk (Asteraceae). The structures of all compounds were established on the basis of 1D, 2D NMR, and EIMS analysis.
