Pharmacognostical and Preliminary Phytochemical Evaluation of Leaf of Blepharis Maderaspatensis Linn

Blepharis maderaspatensis Linn. (Family: Acanthaceae) is a perennial herb traditionally used in the treatment of wounds, ulcers, boils, and eye diseases¹. Despite its wide ethnomedicinal relevance, detailed pharmacognostical and phytochemical documentation remains scarce. The present study was undertaken to establish diagnostic features and preliminary phytochemical standards for this plant. Although Blepharis maderaspatensis is widely used in traditional medicine, comprehensive scientific validation is lacking, and so far, no major research has been carried out on its efficacy from an Ayurvedic perspective. The leaves were collected from their natural habitat, authenticated, shade-dried, powdered, and subjected to macroscopic, microscopic, and powder microscopy investigations. Preliminary phytochemical screening was also performed using standard protocols. Macroscopic evaluation revealed simple, ellipticovate leaves arranged in whorls of four, with entire to slightly toothed margins, dark green upper surface, pale green lower surface, and an astringent taste. Microscopic studies showed dorsiventral differentiation2,3 Diacytic stomata, single-layered epidermis with cuticle, parenchymatous ground tissue, xylem, phloem, and abundant calcium oxalate crystals. Powder microscopy confirmed the presence of epidermal cells, fibres, trichomes, tracheid's, and pitted vessels. Phytochemical analysis indicated the presence of alkaloids, phenolic compounds, flavonoids, tannins, saponins, steroids, carbohydrates, and terpenoids, with ethanolic extract showing the highest extractive value (6%). These findings provide baseline data for proper identification, authentication, and future standardization of Blepharis maderaspatensis Linn. for pharmacological and therapeutic applications.
