Maytenus aquifolium (Celastraceae) and Salacia campestris (Hippocrateaceae) species
accumulate friedelane and quinonemethide triterpenoids in their leaves and root bark …

Among the biologically active triterpenes, friedelin has the most-rearranged structure
produced by the oxidosqualene cyclases and is the only one containing a cetonic group. In …

Abstract The native Brazilian plant Maytenus ilicifolia accumulates a set of quinone methide
triterpenoids with important pharmacological properties, of which maytenin, pristimerin and …

Main conclusion An oxidosqualene cyclase (PdFRS) from Populus davidiana was
characterized as a monofunctional friedelin synthase by its heterologous expression in yeast …

The first committed step in triterpenoid biosynthesis is the cyclization of oxidosqualene to
polycyclic alcohols or ketones C 30 H 50 O. It is catalyzed by single oxidosqualene cyclase …

Phytochemical investigation of the outer root bark of Salacia reticulata var. β-diandra
(Celastraceae) has resulted in the isolation of two novel quinonemethide triterpenoids …

The regulation of triterpenoid saponin biosynthesis in Gypsophila paniculata and Saponaria
officinalis suspension cells has been investigated by studying the effects of adding …

The quinone-methide triterpenoids (QMTs) are chemotaxonomic markers of the family
Celastraceae and many compounds of this class possess important anticancer and anti …

Triterpenes are among the most diverse plant natural products, and their diversity is closely
related to various triterpene skeletons catalyzed by different 2, 3oxidosqualene cyclases …

Five different morphological types of Maytenus ilicifolia of the same age and harvested
under the same conditions showed distinct accumulations of some friedonoroleananes. A …
