Two new sesquiterpene lactones, 8α-acetoxy-1,10α-epoxy-2-oxo-guaia-3,11(13)-dien-12,6α-olide (1) and 13-acetoxy-1-oxo-4α-hydroxy-eudesman-2(11)-dien-12,6α-olide (2), along with six known analogs (3-8), were isolated from the whole plant of Artemisia anomala S. Moore. Their structures were elucidated by extensive analysis of spectroscopic data. Compounds 6 and 7 exhibited in vitro moderate cytotoxicity...
Three new germacranolides, ineupatolides A–C (1–3), together with six known sesquiterpenoids, were isolated from the aerial parts of Inula cappa (Buch.-Ham.) DC. The structures of new compounds were elucidated by 1D-, and 2D-NMR techniques including HMQC, HMBC, 1 H– 1 H COSY and ROESY spectra. The known compounds were identified by spectroscopic data analyses and data comparison. Compound...
