Synthetic Esterification of Yacon Sesquiterpene Lactone, Sonchifolinic Acid led to Cytotoxic SARs Study

The Antiinflammatory Sesquiterpene Lactone

Guaiane sesquiterpene lactones and amino acid-sesquiterpene lactone conjugates from the aerial parts of Saussurea pulchella.

Two new guaiane sesquiterpene lactones ( 1 and 2) and seven new amino acid-sesquiterpene lactone conjugates ( 3- 9), together with six known sesquiterpene lactones ( 10- 15), were isolated from the methanol extract of the aerial parts of Saussurea pulchella. Their structures were determined on the basis of spectroscopic and chemical methods to be 8alpha- O-(3'-hydroxy-3'-methylbutyryl)desacylcy...

Phytochemical Review Profile of Sesquiterpene Lactone Parthenin

Parthenin (a sesquiterpene lactone) is a major constituent of parthenium hysterophorus –a noxious weed known for its environmental and health hazardous properties. . It is responsible for imparting the several properties to this weed such as allelpathy, autotoxicity and allergencity. Further, anticancerous, antiameobic and antimalarial properties of the weed are also credited to parthenin. The ...

Aromaticine, a sesquiterpene lactone from Amblyopappus pusillus

AROMATICINE (SYSTEMATIC NAME: 4a,8-dimethyl-3-methyl-ene-3,3a,4,4a,7a,8,9,9a-octa-hydro-azuleno[6,5-b]furan-2,5-dione), C(15)H(18)O(3), is a natural lactone isolated from Amblyopappus pusillus. The mol-ecular structure and conformation agree with the results of Romo, Joseph-Nathan & Díaz [(1964 ▶). Tetra-hedron, 20, 79-85]. The fused-ring system contains a seven-membered ring in a twist-boat co...

Cynaratriol, a sesquiterpene lactone from Centaurea musimomum

THE TITLE COMPOUND [SYSTEMATIC NAME: 3,8-dihydr-oxy-3-(hydroxy-meth-yl)-9-methyl-6-methyl-enedeca-hydro-azuleno[4,5-b]furan-2(3H)-one], C(15)H(22)O(5), is a sesquiterpene lactone showing the typical tricyclic guaianolide skeleton which has been isolated, together with other related metabolites, from the plant Centaurea musimomum. The present study confirms the mol-ecular structure, assigned by ...
