<jats:title>Abstract</jats:title><jats:p>The chemical investigation of the liverwort <jats:italic>Corsinia coriandrina</jats:italic>, Corsiniaceae, resulted in the isolation, structure elucidation and synthesis of four sulfur‐ and nitrogen‐containing compounds. The coriandrins were identified as (<jats:italic>Z</jats:italic>)‐ and (<jats:italic>E</jats:italic>)‐2‐(4‐methoxyphenyl)ethenyl isothiocyanates, while the <jats:italic>O</jats:italic>‐methyltridentatols contain the corresponding (<jats:italic>Z</jats:italic>)‐ and (<jats:italic>E</jats:italic>)‐<jats:italic>S</jats:italic>,<jats:italic>S</jats:italic>‐dimethyl 2‐(4‐methoxyphenyl)ethenyliminodithiocarbonate structures.
