A process for the production of .beta.-carboline derivatives of general formula I (I), in which X represents a hydrogen atom or a halogen atom, Y represents a carbon-oxygen bond or a methyl group, R1 represents an alkyl group with up to 6 carbon atoms and R2 represents an alkyl group with up to 4 carbon atoms, from 1,2,3,4-tetrahydro-.beta.-carboline derivatives of general formula II (II), in which X, Y, R1 and R2 have the above-mentioned meaning, is described, which is characterized in that the 1,2,3,4-tetrahydro- .beta.-carboline derivatives are fermented with a fungi culture of genus Fusarium or Myrothecium.
