Abstract

This study was conducted to determine the histochemical constituents on the selected species of Lamiaceae found in De La Salle University – Dasmariñas. Four species were investigated, namely: Coleus amboinicus (oregano), Coleus blumei (mayana), Ocimum sanctum (sulasi) and Orthosiphon aristatus (balbas pusa). The roots, stems and leaves of each plant species were subjected to histochemical tests, i.e. alkaloids, tannins, glucosides, saponins, oxalic acid and tartaric acid. Results showed that alkaloid is the most abundant histochemical constituent observed among all plant organs of Coleus amboinicus (oregano), Coleus blumei (mayana), Ocimum sanctum (sulasi) and Orthosiphon aristatus (balabas pusa). Coleus amboinicus (oregano) has the most number of histochemical constituent namely: alkaloid, glucoside, saponin, oxalic acid and tartaric acid. The roots of the Lamiaceae species have the most number of constituents because it contains five out of the possible six constituents tested. Tannin is not observed in all plant organs of the four Lamiaceae species. Base on the results, it has been proven that selected Lamiaceae species contain important histochemical constituents.
