Abstract

From the fresh leaves or twigs of Aptenia cordifolia, a total of 29 compounds were isolated, including the new tetranoroxyneolignan 18, the new dilignan 19, and the β‐ionone derivative 27, previously only known as a synthetic compound, together with 26 known compounds. The structures of the new products were determined by ^1^H‐, ^13^C‐, and 2D‐NMR, as well as HR‐MS analyses. The phytotoxic effects of the isolates on the germination and growth of the dicotyledon Lactuca sativa L. (lettuce) were studied in the concentration range 10^βˆ’4^ to 10^βˆ’7^β€…M. Several constituents of A. cordifolia were found to be equally active as or superior to 4‐hydroxybenzoic acid (HBA) used as positive control.

Seventeen extracts and seven secondary metabolites isolated from basidiomycetes were tested in medium culture against promastigote forms of Leishmania spp. and bloodstream forms of Trypanosoma cruzi. Extracts from the culture filtrate or mycelium were generally inactive against the parasites except
