Sesquiterpene Lactones from Aegialophila pumila
Planta Medica, 1984Cnicin was isolated as the major sesquiterpene lactone from Aegialophila pumila Jus. Boiss. The germacranolide salonitenolide was isolated as a minor constituent. Cnicin demonstrated pronounced cytotoxic activity when tested in vitro against TLX-5 mice lymphoma cells.

Sesquiterpene lactones of Centaurea scoparia
Phytochemistry, 1998From the ethanolic extract of the aerial parts of Centaurea scoparia four new sesquiterpene lactones, belonging to the guaiane class, were isolated and identified, together with a known germacranolide. The structures were elucidated by spectroscopic methods including one- and two-dimensional NMR studies.

Cytotoxic sesquiterpene lactones fromSaussurea calcicola
Archives of Pharmacal Research, 2005Seven sesquiterpene lactones were isolated by the chromatographic separation of the MeOH extract of the aerial parts of Saussurea calcicola (Compositae). Their structures were determined spectroscopically to be cynaropicrin (1), arguerin B (2), cebellin F (3), 8alpha-hydroxy-11alpha, 13-dihydrozaluzanin C (4), desacylcynaropicrin (5), 3beta-hydroxy ...

11,13-Methylene derivatives of sesquiterpene exomethylene-γ-lactones were prepared by reaction of diazomethane and photolysis of the resulting pyrazoline adduct(s). Variable amounts of exomethylene- and ethylidene-γ-lactones were also formed in the photolysis reaction.

Sesquiterpene lactones from Smyrnium olusatrum
Phytochemistry, 2001Fruits of Smyrnium olusatrum afforded three sesquiterpene lactones, namely, 1beta,8beta-dihydroxyeudesman-3,7(11)-dien-8alpha,12-olide, 1beta,8beta-dihydroxyeudesman-4(15),7(11)-dien-8alpha,l2-olide, and 1beta,10alpha,4alpha,5beta-diepoxy-6beta-hydroxyglechoman-8alpha,12-olide. Four related known sesquiterpenes were also isolated and characterized. The
