A chemotaxonomic study of endemic species of genus Tanacetum from the Canary Islands

Germacranolides and Their Diversity of <i>Eupatorium heterophyllum</i> Collected in P. R. China

“…Previous examples of identifying hydroperoxides of a germacrane type [33][34][35][36][37][38] as well as antimicrobial and nuclear factorkappa B (NF-κB) inhibitory activity [38][39][40] have been reported. Therefore, cytotoxicity was tested for hydroperoxyheterophyllin A (1), hiyodorilactone A (11), hiyodorilactone B (12), hiyodorilactone D (14), and eupatoriopicrin (20) on MiaPaCa-2 and AsPC-1 cell lines.…”

Anti-inflammatory sesquiterpenes from the medicinal herb Tanacetum sinaicum

“…Sesquiterpene lactones and flavonoids, in addition to functioning as taxonomic traits for plant systematists in the genus Tanacetum, 1,2 can also function as anti-inflammatory agents. The genus Tanacetum comprises approximately 150 species located throughout Europe and Asia from the Mediterranean to Iran with many plants in the genus having been investigated for their traditional uses in medicine.…”

Sesquiterpene lactones from the aerial parts of Vernonia blumeoides growing in Nigeria

“…In the IR spectrum, absorption bands of hydroxyl (3530 cm À1 ) and ester carbonyl (1782 and 1736 cm À1 ) were observed. The 1 H and 13 C NMR data (Table 1) showed resonances typical of an eudesmane sesquiterpene skeleton similar to 1a,8a-dihydroxy-5aH,10a-eudesma-3,11(13)-dien-6-olide (10) (Triana et al, 2013) H-20), an oxygenated methine resonance at d H 5.08 (1H, q, J = 6.2, H-18), two additional acetyl groups at C-18 and C-1 (d C 169.2, 20.7 and 170.1, 20.9) and an additional tertiary carbon at d C 76.2 (C-17).…”
