ABSTRACT

Background: Stachytarpheta jamaicensis (L.) Vahl. (Verbenaceae) is a common weed and ornamental plant, well-known as Brazilian tea, Aaron’s rod. Ethnomedical survey reveals the use of this plant in diabetes and many other disease conditions. Establishing a preliminary analytical profile of the herb is a prerequisite to its use in clinical conditions. Hence the present study was undertaken with the objective to establish analytical standards of Stachytarpheta jamaicensis (L.) Vahl. plant & tablet. Material & methods: The aerial part of the plant was collected, authenticated and subjected to macroscopic, microscopic, physico-chemical, preliminary phytochemical analysis using standard methodology. High performance thin layer chromatography was performed with Gallic acid as reference standard. Results: The macroscopic & microscopic features show unique characters of the plant. The preliminary phytochemical analysis revealed the presence of carbohydrates, proteins, saponins, tannins in aqueous & alcoholic extracts, while alkaloids, glycosides, flavonoids were detected in alcoholic extract only. HPTLC analysis revealed 2 spots (Rf value 0.22,0.36) under UV short wave, 6 spots (0.14, 0.22,0.28, 0.36, 0.49, 0.70) under UV long wave in both powder & tablet. Discussion & conclusion: The results obtained from the present study serves as a reference standard for Stachytarpheta jamaicensis (L.) Vahl. and its tablet. The product may further be evaluated for its medicinal uses. Keywords: Stachytarpheta jamaicensis (L.) Vahl., Pharmacognosy, phytochemistry, Diabetes mellitus, Gallic acid
