This study underscores the organ-specific distribution of metabolites in Hyptis suaveolens L., highlighting its pharmacognostically significance. The analysis focused on key components such as starch, protein, tannins, fats, saponins, alkaloids, and glucosides. Starch was localized in the epidermis and Exodermis of the root, the stem's vascular bundles, cortical parenchyma, and cortex, as well as in the leaves' vascular bundles and palisade parenchyma. Proteins were present in the root’s cortex, vascular bundles, and Exodermis, while in the stem, they were found in the xylem, phloem, cortex, Pericycle, and medullary rays. In leaves, protein localization included vascular bundles, palisade, mesophyll, and parenchyma. Tannins were detected in the medullary rays and epidermis of the root, the vascular bundles and cortical cells of the stem, and the palisade and mesophyll cells in the leaves. Saponins appeared in the root’s Pericycle, cortex, endodermis, and Exodermis, as well as in the stem's xylem and leaves' vascular bundles.
