Triterpenes from Adiantum lunulactum
Fitoterapia, 2002The petrol extract of the whole plant of Adiantum lunuactum yielded a new hopane triterpenoid characterized as 6 alpha-acetoxy-16 beta,22-dihydroxy-3-ketoisohopane, along with the known 3beta,6 alpha,16 beta,22-tetrahydroxyisohopane (mollugogenol A). The structures were elucidated by spectral as well as chemical studies.

Antitumoractive Endoperoxides from Triterpenes
Archiv der Pharmazie, 2009AbstractA series of triterpene endoperoxides was synthesized and screened for antitumor activity in a panel of 15 human cancer cell lines by a sulforhodamine‐B (SRB) assay. The compounds induce apoptosis and show excellent antitumor activity.

Differential Partitioning of Triterpenes and Triterpene Esters in Apple Peel
Journal of Agricultural and Food Chemistry, 2018Apple peel is a rich source of secondary metabolites, and several studies have outlined the dietary health benefits of ursane-type triterpenes in apple. Changes in triterpene metabolism have also been associated with the development of superficial scald, a postharvest apple peel browning disorder, and postharvest applications of diphenylamine and 1 ...

Cytotoxic triterpenes fromCrataegus pinnatifida
Archives of Pharmacal Research, 2000Bioassay-guided fractionation of Crataegus pinnatifida (Rosaceae) gave two cytotoxic ursane-type triterpenes which were identified as uvaol (1) and ursolic acid (2) by physicochemical and spectroscopic methods. 3-Oxo-ursolic acid (3) was synthesized from ursolic acid (2) by Jones method.

Journal of Pharmaceutical Sciences, 1961
A water extract of the fungus Poria obliqua has been shown to possess tumor-inhibiting activity against two test tumors. Two triterpene alcohols were isolated from the hexane extract, one of which was identified as lanosterol. The second, named obliquol, C30H50O2, was shown to have two hydroxyl groups and two double bonds, one of which is inert to ...

Triterpene antioxidants fromGanoderma lucidum
Phytotherapy Research, 1999Ganoderma lucidum was studied for its antioxidative activity by bioassay guided isolation in conjunction with in vitro tests. The powdered crude drug was treated with boiling water and the aqueous extract (Ex1) was further separated to obtain terpene and polysaccharide fractions.

Triterpene Glycosides fromAstragalus angustifolius
Planta Medica, 2012Six new cycloartane-type (1- 6) and four new oleanane-type (7- 10) triterpene glycosides were isolated from Astragalus angustifolius Lam., together with five known triterpene glycosides. Their structures were established by the extensive use of 1D and 2D-NMR experiments along with ESIMS and HRMS analysis.

Lupane-triterpenes fromBupleurum flavum
Natural Product Research, 2005Two new triterpenoids, lup-20(29)-en-3 alpha, 28-diol (1) and lup-20(29)-en-3 alpha, 28,30-triol (2), have been isolated from aerial parts of Bupleurum flavum, a native plant of the Eastern Mediterranean area (Bulgaria, Greece, and Turkey). Their structures were elucidated by spectral analysis.
