FUNASAKI, Mariko et al. Neolignans and sesquiterpenes from leaves and embryogenic cultures of Ocotea Catharinensis (Lauraceae). J. Braz. Chem. Soc. [online]. 2009, vol.20, n.5, pp.853-859. ISSN 0103-5053.

The extracts from leaves of Ocotea catharinensis Mez (Lauraceae) were found to contain fourteen neolignans and two sesquiterpenes: nine benzofuran types (including three new compounds 1e, 2f and 4b), one new seco-benzofuran type (3b), two bicyclo[3.2.1]octane types (including the new compound 5c), two new dimers of bicyclo[3.2.1]octane type (7a and 7b) and two sesquiterpenes (including a new humulanol 9). In addition, seven neolignans were also showed to occur in somatic embryos of O. catharinensis including one new bicyclo[3.2.1]octane type (4a).

Keywords : Ocotea catharinensis; benzofuran neolignans; bicyclo [3.2.1] octane neolignans; humulane sesquiterpene; somatic embryos.
