By definition triterpenoids are triterpenes that possess heteroatoms, usually oxygen. The terms triterpene and triterpenoid often are used interchangeably. Triterpenoids possess a rich chemistry and pharmacology (e.g. cholesterol) with several pentacyclic motifs. Lupane, oleanane and ursane show particular promise as anti-cancer agents. [5] [6]
They are designated α-amyrin (ursane skeleton), [3] β-amyrin (oleanane skeleton), [4] and δ-amyrin. Each is a pentacyclic triterpenol with the chemical formula C 30 H 50 O. They are widely distributed in nature and have been isolated from a variety of plant sources such as epicuticular wax .

Oleanane is a natural triterpenoid.It is commonly found in woody angiosperms and as a result is often used as an indicator of these plants in the fossil record. It is a member of the oleanoid series, which consists of pentacyclic triterpenoids (such as beta-amyrin and taraxerol [verification needed]) where all rings are six-membered.

The terpenoids, also known as isoprenoids, are a class of naturally occurring organic chemicals derived from the 5-carbon compound isoprene and its derivatives called terpenes, diterpenes, etc.
Chemically, phytoecdysteroids are classed as triterpenoids, the group of compounds that includes triterpene saponins, phytosterols, and phytoecdysteroids. Plants, but not animals, synthesize phytoecdysteroids from mevalonic acid in the mevalonate pathway of the plant cell using acetyl-CoA as a precursor.
Steroid glycosides are saponins with 27-C atoms. [4] They are modified triterpenoids where their aglycone is a steroid, these compounds typically consist of a steroid aglycone attached to one or more sugar molecules, which can have various biological activities.
