Detection of aristolochic acids I and II in “Chiniy-trèf”, a traditional medicinal preparation containing caterpillars feeding on Aristolochia trilobata L. in Martinique, French West Indies

Abstract “Chiniy-tref” is a traditional medicinal preparation used in Martinique, French West Indies, for the prevention of all kinds of attempted poisoning and hex. It is produced by the maceration in alcohol (mostly rum) of larvae (caterpillars) of the butterfly Battus polydamas ssp. cebriones, feeding on the leaves of Aristolochia trilobata. Aristolochic acids I and II that are well-known nephrotoxic and carcinogenic substances were identified on two samples of “chiniy-trefl” by chromatographic methods.
