Histochemical analysis of the ground part of garden pursuit

Histochemical analysis reveals the presence and placement of secondary metabolites in tissues and organs. Portulaca oleracea is used in folk medicine, a widespread annual plant. This article presents results of histochemical analysis of the leaves, flowers and stems of Portulaca oleracea L. The study of the aerial organs of Portulaca oleracea L. by light microscopy in combination with histochemical reactions was performed for the first time. As a result of the carried out histochemical reactions, phenolic compounds, flavonoids, traces of alkaloids, sesquiterpene lactones, inulin, and polysaccharides were found on the cross sections of the leaf, stem and whole flower, and their localization was established. The results of histochemical studies were used to confirm the authenticity, identification and standardization of aboveground parts of Portulaca oleraceae (Portulaca oleracea L.).
