Aerial parts of Inula montana were investigated for its sesquiterpenoid composition. Five sesquiterpene lactones, isoinuviscolide, gaillardin, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15), 11(13)-dien-12-8beta-olide, pulchellin-C and pulchellin-E were identified for the first time in this plant. One of

Inula oculus-christi L. (Compositae) extract was chromatographed and three sesquiterpene lactones ergolide, gaillardin and pulchellin C were isolated. The structures of these compounds were determined by analysis of their spectroscopic data, and their crystal structures were defined using X-ray

Pulchellin E (1) and gaillardin (2) were isolated from the aerial parts of Inula oculus-christi, along with the flavone hispidulin. The 13C-NMR chemical shifts of 1 and 2 are reported.

Background and the purpose of the study: The amount of elder people who suffer from Alzheimer disease is continuously increasing every year. Cholinesterase inhibitors have shown to be effective in alleviating the symptoms of the disease, thus opening a field of research for these treatments. Herbal

The flower heads of Inula britannica L. of Bulgarian origin afforded sesquiterpene lactones (gaillardin, britannin, I1, 13-dihydroinuchinenolide B, ivalin, pulchellin C), triterpenoids (3-0-palmitates of 160-hydroxylupeol, 16β-hydroxy-β-amyrin, and faradiol) and flavonoids (quercetin, luteolin,

OBJECTIVE To investigate the sesquiterpene lactones of the aerial parts of Inula helianthus-aquatica. METHODS Compounds were isolated and purified by silica gel, Sephadex LH-20 and preparative HPLC. On the basis of physicochemical properties and spectroscopic data, their structures were
