"Preliminary pharmacochemical research on Lysimachia nummularia L. was performed by dint of pharmacognostic analysis (macroscopic examination, global chemical analysis, preliminary quantitative determinations).The article includes the analysis of the macroscopic characters of the vegetative organs (root, stem and leaf), as well as of the reproductive organs (flower, fruit, seed) belonging to the spontaneous native species Lysimachia nummularia L. Morphological features were described and discussed. The identification of these aspects was done with the naked eye, but also with the help of a hand magnifier and a binocular magnifier. The results revealed that the external appearance of the plant justifies the species belonging to the genus Lysimachia, family Primulaceae. They are found in the glabrous and creeping appearance of the plant, opposite, almost round leaves, solitary, yellow flowers, axillary with vigorous pedicels, perianth pentamer, actinomorphic, dialisepal and dialipetal, globular capsule fruit. The semi-hydrophilic nature is found in the presence of adventitious roots that develop both from the rhizome and at the nodes of the stem. The preliminary quantitative determinations performed were loss by drying as well as soluble substances of the species Lysimachia nummularia L. Following the global chemical analysis, active principles known in the literature for the antioxidant potential were identified. Following the preliminary quantitative determinations (drying loss, determination of soluble substances) results comparable to those in the literature on the content of volatile substances and soluble substances were obtained."
