  • We have previously reported that piperine, a known piperidine alkaloid from Piper longum, competitively inhibited mouse brain MAO-A and MAO-B activities. Piperine also showed in vivo antidepressant-like activity against the tail suspension test. In the present study, we further expanded on the identification of MAO inhibitors from the fruit of P. longum. Activity-guided fractionation of a methylene chloride soluble extract led to the isolation of three known piperine-related compounds… CONTINUE READING
