Z. fabago, P. harmala and Z. elephantidens are mentioned on page 14 of Sniekus citing Ivanov et al. 1965 and Awad et al. 1967.

Fagonia bruguieri DC, Zygophyllum coccinum L & Zygophyllum fabago L. had alkaloid detected in Al-Shamma & Mitscher 1979


In Francesco Festi and Giorgio Samorini's excellent profile of Tribulus terrestris [in 1997 Eleusis 7: 24-32] they mentioned:

Fagonia cretica was reported to contain small amounts of harmine.

Tribulus terrestris (Caltrop; Tribolo; Puncture-vine; Goat's-head) contains low concentrations of b-carbolines; a small percentage of which is harmine. Traces of harmine were reported from the seeds.

Zygophyllum fabago was reported to contain 0.002% harmine; using the whole plant.


All three contain other alkaloids.

Note: Porlieria angustifolia is also called Caltrop. The Zygophyllaceae is usually referred to as the Caltrop family or simply the Caltrops.
