There are about 150 species of Ocimum in the world and out of that 68 species are found in India. Comparative pharmacognostic study of these Ocimum species is unspecified. Growing demand of Ocimum plants demands quality standards for correct identification of desired Ocimum species. Objectives: Hence aim of present study is to establish comparative pharmacognostical, phytochemical and biological standards for most commonly found and morphologically confusing five species of Ocimum. Methods: Macroscopic, microscopic, preliminary phytochemical evaluations, extraction of essential oils, TLC analysis, in vitro antioxidant and antimicrobial potency of selected five species carried out and compared. Results: This comparative study reports that O. sanctum should be preferred in medicine use among selected five species based on phytochemical composition, antioxidant and antimicrobial potency.

Blepharis repens (Vahl) Roth of Acanthaceae family, commonly known as Hadsan in Marathi and Haridachchu in Kannada, is threatened species due to exploitation from natural habitat. Objectives: The objective of present study is to establish scientifically well evaluated pharmacognostic and biological efficacy parameters. Methods: Microscopical parameters of leaf, root and stem are evaluated. Powder microscopy, physicochemical analysis, elemental analysis, fluorescence analysis, preliminary phytochemical screening and estimation of major phytoconstituents of whole herb powder are carried out. In vitro biological evaluation of Blepharisrepens carried out for antioxidant potential by DPPH method, in vitro anticancer activity by SRB assay and antimicrobial efficacy by both agar well diffusion and bioautography methods. Results: Morphologically, roots are cylindrical and elongated, leaf has symmetric base, entire margin, acute apex while stem is cylindrical, elongated. Microscopic evaluation reveals that both leaf and stem are covered with trichomes. Leaf has unicellular uniseriate trichomes while stem has multi-cellular uniseriate covering trichomes. Physicochemical evaluation revealed that total ash, acid insoluble ash and water-soluble ash values 13.85 7.7 and 3.1\% respectively. Petroleum ether, alcohol and water extractive values found 0.84\%, 1.64\%, and 3.52\% respectively. Loss on drying value is found 3.43\%. Element analysis of whole herb confirms presence of nitrogen, sulphate and carbonate. Fluorescence tests are performed by treatment with different acids and alkalis and exposure to ultraviolet light. Phytochemical screening shows presence of carbohydrates, alkaloids, tannins, flavonoids and saponins. Estimation of phytochemicals like carbohydrate, alkaloid, tannin and flavonoid found 5.78\%, 1.43\%, 5.7\% and 1.48\% respectively. Biological evaluation reveals that plant has significant antioxidant and antimicrobial activity while plant is devoid of in-vitro anticancer activity against human leukemia cell line HL-60.
