Triterpene Biosynthesis in Plants
Annual Review of Plant Biology, 2014The triterpenes are one of the most numerous and diverse groups of plant natural products. They are complex molecules that are, for the most part, beyond the reach of chemical synthesis. Simple triterpenes are components of surface waxes and specialized membranes and may potentially act as signaling molecules, whereas complex glycosylated triterpenes ...

Triterpenes and a triterpene glucoside from Dysoxylum cumingianum
Phytochemistry, 2011Six triterpenes and a triterpene glucoside were isolated from the MeOH extract of the leaves of Dysoxylum cumingianum together with three known triterpenes. Their structures were elucidated by extensive spectroscopic analyses. In cytotoxicity assays against three human cancer cell lines, including a multi-drug resistant cancer cell line (KB-C2 ...

Triterpenes and triterpene glycosides from Paradrymonia macrophylla
Phytochemistry, 1996Abstract Seven pentacyclic triterpenes and triterpene glycosides have been isolated from the stems and roots of Paradrymonia macrophylla and their structures elucidated by means of 1H and 13C NMR spectroscopy. Three of them are described for the first time as natural products, namely: 2α,3β,19α-trihydroxy-24-oxo-urs-12-en-28-oic acid (24-epi ...

Triterpenes fromMucuna birdwoodiana
Phytochemistry, 1991Methanolic extracts of the stalks of Mucuna birdwoodiana on acid hydrolysis and subsequent methylation with diazomethane provided four triterpene sapogenols. On the other hand, investigation of glycosides after methylation of the same extract led to the isolation of four triterpene glycosides.

Triterpene und Triterpen-Saponine
1955Triterpene sind Naturstoffe mit 30 C-Atomen. Der Aufbau ihres Molekuls folgt der „Isoprenregel“, d. h. das Kohlenstoffskelet last sich in 6-Isoprenreste zerlegen (s. die Formeln I, III, IV, V). Die Mannigfaltigkeit der Korperklasse wird durch die Abanderungen des Kohlenstoffskelets, durch Zahl und Stellung der Doppelbindungen und der ...

Triterpenoids belong to a large and structurally diverse class of natural products which occur abundantly in plant kingdom, especially in higher plants in cases of pentacyclic and tetracyclic triterpenes, while mono-, bi-, and tricyclic triterpenes are prevalent in ferns and nonflowering lower plants (cryptogams).

Triterpenes from Licania licaniaeflora
Fitoterapia, 2001Nine triterpenoids with lupane, oleanane, and ursane skeleton have been isolated and characterized from the leaves of Licania licaniaeflora. The structural identification was based on (1)H and (13)C-NMR spectral data.
