b> Abstract Previous chemical studies on specimens of Huperzia saururus (Lam.) Trevis. collected in different parts of the world showed significant differences in the alkaloid content. In Córdoba (Argentina) the chemical pattern was characterized by the presence of three main alkaloids: sauroine, sauroxine, and 6-hydroxylycopodine. This fact remarkably differs from the patterns informed for specimens collected in Quito (Ecuador), Kahuzi and Ruwenzori (Zaire), and Sabyinyo (Rwanda) where their marker alkaloids are clavolonine and lycopodine that in time differ from those mentioned by other authors of unknown specimen provenance. As a consequence, we undertook a seasonal study by analyzing the qualitative-quantitative content of alkaloids by using GLC-MS and GLC-FID resp
