Isolation and Biological Evaluation of Triterpenes from Leaves.

is naturally found in the Atlantic Forest regions of Brazil. Despite the pharmacological potential of plants from the genus, phytochemical studies on this species have not been reported in literature. A new triterpene, 28-hydroxyfriedelane-3,15-dione (), and seven known compounds (friedelan-3-one (), friedelan-3β-ol (), friedelane-3,15-dione (), 15α-hydroxyfriedelan-3-one (), 28-hydroxyfriedelan-3-one (), 30-hydroxyfriedelan-3-one (), and 29-hydroxyfriedelan-3-one ()) were obtained from the hexane extract of leaves.

Pentacyclic Triterpenoids Isolated from Celastraceae: A Focus in the C-NMR Data.

The Celastraceae family comprises about 96 genera and more than 1.350 species, occurring mainly in tropical and subtropical regions of the world. The species of this family stand out as important plant sources of triterpenes, both in terms of abundance and structural diversity.
