Sesquiterpene Lactones as Allelochemicals
Journal of Natural Products, 2006Six new sesquiterpene lactones, annuolide H (3), helivypolides F, H-J (4, 11-13), and helieudesmanolide A (6), together with known compounds, were isolated from polar bioactive fractions of Helianthus annuus cv. SH-222 and Stella fresh leaf water extracts.

AbstractOf the 4000 or so terpenoid natural products known today, whose carbon skeleton can be divided up into isopentane units by the “isoprene rule” (C10, monoterpenes; C15, sesquiterpenes; C20, diterpenes; C25, sesterterpenes; C30, triterpenes; steroids; carotenoids; polyprenes), the sesquiterpenes, numbering about 1000, represent the largest single

Hepatotoxicity of monoterpenes and sesquiterpenes
Archives of Toxicology, 2017Public interest in natural therapies has increased significantly over past decades. Herbs and herbal products are extensively consumed worldwide and they are generally considered as safe. However, this may not always be true as many cases of herb-induced liver injury are reported every year.

Elemanolide sesquiterpenes and eudesmane sesquiterpene glycosides from Centaurea hierapolitana
Phytochemistry, 2007Two elemanolide sesquiterpenes and two eudesmane-type sesquiterpene glycosides named hierapolitanins A-D, were isolated, together with five known compounds, two flavones; hispidulin and jaceosidin, a flavon-C-glycoside, shaftoside, a flavonol glycoside, kaempferol-3-O-rutinoside and a neolignan, dehydrodiconiferyl alcohol from the aerial parts of ...

Sesquiterpene coumarins and sesquiterpenes from Ferula sinaica
Phytochemistry, 1999Further study on the methylene chloride extract of roots of Ferula sinaica has resulted in the isolation of six sesquiterpene coumarins, of which two were new, six sesquiterpenes, including a new one, and a known monoterpene. The structure of the new compounds was established by high-field NMR analysis.
