Chemistry and Biological Activities of Terpenoids from Copaiba (Copaifera spp.) Oleoresins

Molecules, 2012
Copaiba oleoresins are exuded from the trunks of trees of the Copaifera species (Leguminosae-Caesalpinoideae). This oleoresin is a solution of diterpenoids, especially, mono- and di-acids, solubilized by sesquiterpene hydrocarbons. The sesquiterpenes and

Kaurane-Type Diterpenes from Fern Frond Exudates

Zeitschrift für Naturforschung C, 1989
Abstract The viscid exudate found on fronds of the fern, Cheilanthes kaulfussii, consists of terpenoids in which flavonoid aglycones are dissolved. One of the terpenes is shown to be em-kaur-16-en-19-oic acid. The farinose frond exudate of Notholaena pallens contains this acid as the major constituent and its 3 R-hydroxy derivative ...
