Triterpenes are terpenes consisting of six isoprene units and have the molecular formula C30H48.
The pentacyclic triterpenes can be classified into lupane, oleanane or ursane groups.[1]
A notable pentacyclic triterpene is Boswellic acid.
Animal- and plant-derived triterpenes exist, such as:
- squalene
- ambrein (a tricyclic triterpene alcohol)
- ganoderic acid (quad cyclic)
Triterpenoids are thought of as modified triterpenes, such as lanosterol.
