Propolis samples from north-west Argentina (Amaicha del Valle, Tucumán,) wereevaluated by palynology, FT-IR spectra, and RP-HPTLC. In addition, the volatilefraction was studied by HS-SPME-GC-MS. The botanical species most visited by Apismellifera L. near the apiaries were collected and their RP-HPTLC extracts profiles werecompared with propolis samples. In addition, GC-MS was performed for volatilecompounds from Zuccagnia punctata Cav. (Fabaceae). FT-IR spectra and RP-HPTLCfingerprints of propolis samples showed similar profiles. In RP-HPTLC analyses, onlyZ. punctata presented a similar fingerprint to Amaicha propolis. The major volatilecompounds present in both were trans-linalool oxide (furanoid), 6-camphenone,linalool, trans-pinocarveol, p-cymen-8-ol, and 2,3,6-trimethylbenzaldehyde.
