| Paxidal, a sesquiterpene dialdehyde cinnamate constituent, has been identified as a main active constituent. |
| Cadinene, the principal component of oils of cubeb and cade, is a typical sesquiterpene of the cadalene type. |
| Asakawa and Aratani isolated a sesquiterpene dial, polygodial or tadeonal, which had been obtained from Polygonum hydropiper. |
| However, we reported in a previous study that santonin, a eudesmanolide sesquiterpene lactone, exerts no effects on the differentiation of leukemia cells. |
| In those cases in which sulfur dehydrogenation fails to yield information about the carbon skeleton of a sesquiterpene, a systematic degradation by oxidation to compounds of known structure is necessary. |
| But by the 1970s it was known that the lethal chemical, first called qinghaosu and now artemisinin, had a structure never seen before in nature: In chemical terms, it is a sesquiterpene lactone with a peroxide bridge. |
