Eudesmanolides. Sesquiterpene lactones with the eudesmane basic skeleton mainly from Asteraceae. On the basis of the ring closure of the y-lactone group two forms are distinguished the santanolides in which the lactone oxygen is linked to carbon atom 6 (e.g., santonin, artemisin) and the alantolides (e.g., helenin ) in which linkage occurs at carbon atom 8.

Polyynes (polyacetylenes). Compounds with very diverse structures containing several C/C triple bonds are produced mainly by fungi (basidiomycete cultures) and plants of the families Asteraceae, Apiaceae, and Araliaceae. In addition to conjugated triple bonds the R often also contain C/C double bonds, allene units, thiophene and furan rings. On account of the close biosynthetic relationships between these compounds, the term R is used as a collective name even when only one C/C triple bond is present in the molecule. As result of the work of Bohimann, E. R. H. Jones, Sorensen, and others more than one thousand natural R are now known. The antibiotically active mycotnycin (C H, g02, Mr 198.22, mp. 75 °C) from basidiomycete cultures, dehydromatricaria ester (CiiHgO, Mr 172.18, mp. 105-106°C) from Asteraceae, and the thiarubrins may be mentioned as typical examples (see also ter-thienyls). 

CigHjjNOs, Mr 351.40, mp. 217°C (207-208°C), [alg -62.4° (CHCI3), [a]o -17.6° (CjHjOH). R. is a pyrrolizidine alkaloid from Asteraceae (Senecio, Erechtites) and some Crotalaria species (Fabaceae). It exists in the plants as the A(-oxide and is highly toxic, causing liver and kidney cancer (see pyrrolizidine alkaloids).
