What are the pharmacological activities of Peganum harmala?
This plant has potent pharmacological activities including monoamine oxidase A (MAO-A) inhibition, anti-inflammatory, antioxidant, neuroprotective, and antimicrobial properties. Its primary alkaloids act as reversible inhibitors of the MAO-A enzyme, which significantly affects neurotransmitter levels in the brain. The presence of various bioactive compounds allows the plant to combat oxidative stress and reduce systemic inflammation. These combined effects contribute to its ability to provide neuroprotection against various neurodegenerative processes. Additionally, the plant exhibits significant antimicrobial capabilities against a wide range of pathogenic microorganisms.
According to a study published by "Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association", Peganum harmala L. contains main beta-carboline alkaloids including harmaline, harmine, harmalol, harmol and tetrahydroharmine. Dry seeds contain 4.3% (w/w) harmine, 5.6% (w/w) harmaline, 0.6% harmalol, and 0.1% (w/w) tetrahydroharmine, while roots contain 2.0% (w/w) harmine and 1.4% (w/w) harmol. Seed extracts act as potent reversible and competitive inhibitors of human monoamine oxidase (MAO-A) with an IC(50) of 27 microg/l. Root extracts also strongly inhibit MAO-A with an IC(50) of 159 microg/l, though both seed and root extracts are poor inhibitors of MAO-B. This potent inhibition of MAO-A by the plant's beta-carbolines could serve as the basis for its purported antidepressant actions.
