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.

Expression and secretion of recombination proteins in transgenic hairy roots have opened door to simple, feasible and economic option compared to animal and bacterial systems. Here, we report a feasibility study for producing the nontoxic B subunit of Escherichia coli heatlabile enterotoxin (LTB) in Daucus carota L hairy root where transformation is achieved by biolistic gene gun method. Agrobacterium rhizogenes strain (R-1000) cells containing synthetic LTB gene in pMYO51T plant expression vector under the CaMV 35S promoter introduced to Daucus carota L roots by biolistic gene gun method. PCR amplification confirmed the integration of synthetic LTB gene in carrot hairy roots. Western blot analysis confirmed production of LTB pentamer in similar banding pattern to the native bacterial derived LTB. 0.50-0.70\% of LTB protein estimated in carrot hairy roots. GM1-ganglioside assay indicated formation of biological active pentamers. LTB protein with biochemical properties identical to native LTB protein in the hairy roots of edible carrot roots opens the way for inexpensive, safe, and effective plant-based edible vaccines for humans and animals.

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.
