Triterpenes and a triterpene glucoside from Dysoxylum cumingianum

Phytochemistry, 2011
Six 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, 1996
Abstract 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, 1991
Methanolic 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

1955
Triterpene 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 ...

Triterpenes (C30)

2014
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).
