Dynamics of Alkaloid Accumulation in Ephedra Procera aerial Parts According to Phenological Phases

The research focused on the aerial parts of Ephedra procera Fisch. The investigation revealed the presence of acyclic group alkaloids. The study demonstrated a variation in alkaloid content within the aerial parts of Ephedra procera according to different phenological phases. The yield of total alkaloids in the material collected in spring is 0.3%, in the material collected in summer - 0.55 %, in autumn period - 0.72% and in winter - 0.9%, the percentages were calculated based on the air-dried raw material.
