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 with several pentacyclic motifs. Lupane, oleanane and ursane show particular promise as anti-cancer agents. [5][6]

Triterpenoid has been reported in Gomphrena macrocephala with data available. A class of terpenes (the general formula C30H48) formed by the condensation of six isoprene units, equivalent to three terpene units.

Triterpenoids are a group of terpenoids with a basic skeleton consisting of 30 carbon atoms. They exist naturally in plants in a free form or the form of glycosides or esters, and they have a wide range of pharmacologic activities such as anticancer, antiinflammatory, antibacterial, and antiviral.

2020年1月1日 · In this chapter, we present structural diversity and the biosynthetic pathway of plant triterpenoids and also highlight the bioactivities of natural triterpenoids with potential pharmaceutical applications.

2024年7月10日 · Triterpenoids are a large and diverse class of phytochemicals —compounds produced by plants, usually for protective and developmental purposes. They also have potential uses in the food and pharmaceutical industries. Triterpenoids are oxygen-containing derivatives or degradation products of the naturally occurring compound triterpene.

2024年10月21日 · The identification of two tailoring enzymes required for astragaloside biosynthesis enabled the discovery of a triterpenoid biosynthetic gene cluster, leading to elucidation of the complete ...

2022年3月31日 · Triterpenoids are biosynthesized in the endoplasmic reticulum and cytoplasm via the combination of two molecules of farnesyl diphosphate to form a C30 precursor (squalene), which is known as the mevalonate/acetate pathway (Yan et al. 2014).

Here, we have summarized the potential of triterpenoids belonging to the lupane, oleanane, ursane, and cucurbitacin groups, and their beneficial effects based on both laboratory and clinical investigations.

"Triterpenoids" can be considered natural products derived from the cyclization of squalene, yielding 3-deoxytriterpenes (hydrocarbons) or 3-hydroxytriterpenes. Triterpenoids are metabolites of these two classes of triterpenes, produced by the functionalization of their carbon skeleton.
