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 ...

The Antiinflammatory Sesquiterpene Lactone

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...

Dehydro­leucodin: a guaiane-type sesquiterpene lactone

Dehydro-leucodin [systematic name: (1S,6S,2R)-9,13-dimeth-yl-5-methyl-ene-3-oxatricyclo-[8.3.0.0(2,6)]trideca-9,12-diene-4,11-dione], C(15)H(16)O(3), is a guanolide isolated from Artemisia douglasiana. The fused-ring system contains a seven-membered ring that adopts a chair conformation, a fused planar cyclo-pentenone ring and a five-membered lactone ring fused in envelope conformation. The abs...

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 ...
