Compositae tanacetum parthenium

Tanacetum parthenium (L.) Schultz Bip. is the official Latin name for the member of the Compositae family which is more commonly referred to as feverfew [6]. The plant had previously been classified as Chrysanthemum parthenium (L.) Bernh., so the latter name is strictly speaking no longer correct. Other old classifications for feverfew are Leucanthemum parthenium (L.) Gren. Godron or Pyrethrum parthenium (L.) Sm. 

In 1959-61, a Czech group [8,9] reported the isolation of a new sesquiterpene lactone from Chrysanthemum (Tanacetum) parthenium as part of a study of the sesquiterpene lactones of the Compositae family. They named it parthenolide. The initial structure for parthenolide was later revised [10,11] and the accepted structure for parthenolide today is represented by structure (1). Parthenolide is a germacranolide-type sesquiterpene lactone. The crystal structure for parthenolide has also been reported [12]. Extractions of C. (T.) parthenium grown in Mexico, known locally as santamaria, did not yield parthenolide [13], but a closely related compound was isolated and named santamarine (3). This suggests that regional variations in the chemical constituents may occur. 

More than 11,000 Sesquiterpenes have been isolated from natural sources [3]. Feverfew (Tanacetum parthenium (L.) Sch. Bip.,. Compositae) is a common herb utilized for fever, arthritis and migraine. The leaves of feverfew contain large amounts of sesquiterpene lactones. The chloroform extracts of fresh leaves and a commercial leaf product show dose-dependent inhibiting the production of throboxane B2 (TXB2) and leukotriene B4 (LTB4) in rat and human leukocytes. Sesquiterpene lactones isolated from the leaves of feverfew, such as parthenolide and tanaparthin-a-peroxide, demonstrate potent dual inhibitions of COX and LOX pathways with IC50 for COX at 6 17 pg/ml, and for LOX at 12 17 pg/ml, respectively [135],...
