A field study was conducted at the Vegetable Research Farm, Banaras Hindu University, Varanasi, during rabi season 2016-2017 for the evaluation of newer insecticides (Imidacloprid 600 FS and Thiamethoxam 30 % FS) on plant growth characters of a garden pea. The two insecticides were applied as a seed treatment in different doses. The result of bio-efficiency revealed that the seed treatment with T₃ gaucho (Imidacloprid 600 FS) @ 2 ml/kg was found effective in promoting plant growth and increased germination % (93.84%) and maximum plant stand per meter square(m²) (30.40%). Less number of days to 50% flowering (43.33 days) and maximum plant height at last harvesting stage (91.07 cm) were also recorded in seed treatment with T₃ gaucho (Imidacloprid 600 FS), while there was no significant difference in plant height at 30 DAS and 45 DAS. However, all the seed treatment was found superior over untreated...

The present study, carried out on Cymbopogon citratus was interested in volatile and no-volatile extracts of the plant. It focused on the effect of two types of extracts on eleven strains of bacteria. Chemical analysis of the volatile extract obtained with a yield of 2.28% revealed the presence of 72.91% of citral and other minority compounds. The extraction yield of the ethanolic extract (no-volatile) is 10.8%. Chemical groups such as reducing compounds, alkaloids, flavonoids, phenolic compounds, leuco-anthocyanins, saponosides, coumarins, and finally, terpenoids have been identified in this extract. The Minimum Inhibitory Concentration (MIC) and Bactericidal (CMB) were determined by macro dilution method. The volatile extract showed the best inhibitory activities on more than 90% of the strains of bacteria studied. The lowest minimum inhibitory concentrations were obtained against Micrococcus luteus (0.3125 mg/ml), Staphylococcus epidermidis T22695 (0.625 mg/ml) and Proteus vulgaris A25015 (0.625 mg/ml). This extract also had the best inhibition diameters against most bacteria. The bactericidal activity of this extract was only obtained against Enterococcus faecalis (1.25 mg/ml). The...

Marine natural products are currently acknowledged as the most significant source of bioactive substances and medications with phenomenal biodiversity. Marine plants and creatures, for example, algae, bacteria, sponges, fungi, seaweeds, corals, diatoms, ascidians, are significant sources of the ocean and contain over 90% of the complete ocean biomass. Because of its exceptional biodiversity, the sea world is a rich common asset for some biologically active compounds. About half of the world’s biodiversity is a marine organism; thus, the seas and oceans are viewed as the biggest repositories with an immense assortment of new substances and natural molecules of benefit. During the previous four decades, various novel compounds have been confined from a marine organism, and a large number of these substances have been appeared to have intriguing biologic potential.This review is an ongoing update of data about efficient marine eugicons (proteins, peptides, amino acids, fatty acids, sterols, polysaccharides, oligosaccharides, phenolic compounds, photosynthetic pigments, vitamins, and minerals) and spotlight on their potential health benefits. Accordingly, the work assessed so far...

Impatiens minor (DC.) Bennet (Balsaminaceae), a small, slender, erect herb, growing about 10 – 15 cm tall, with glassy stem, with oppositely arranged, elliptiac or ovate-lanceolate leaves and have distantly serrated margins is claimed to have many medicinal properties, but not scientifically proved properly. Systematic pharmacognostical evaluation of aerial parts of the plant has been carried out with focus on its macroscopy, microscopy, physic-chemical and phytochemical characterization. Macroscopical and microscopical features of stem and leaf have been documented. Preliminary phytochemical investigations indicated tests the presence of carbohydrates, alkaloids, triterpenoid, steroid, tannins, glycosides and flavonoids. The result of the study could be useful for the identification and preparation of a monograph of the...

Hylocereus undatusis an important medicinal plant belonging to the family Cactaceae and widely distributed in tropical forest areas. Fruits are used for anti-bacterial, anti-oxidant, antipyretic, antidiabetic and hepato-protective activities of the plants are scientifically proved. The aim of the present study is to evaluate Hylocereus undatus pharmacologically for the anti-oxidant study. The study also includes the Pharmacognostical and phytochemical evaluation of the plant. The pharmacognostic evaluation revealed authentication and identification of the plant and extraction of plant material using ethanol by Soxhlets extraction method. Preliminary phytochemical studies were carried out using various chemical tests. Phytochemical studies showed the presence of glycoside, phenolic, flavonoids, triterpenoids, tannins and reducing sugar. The phenolic content of the ethyl acetate extract of the roots separated by chromatographic technique and the total phenolic content was calculated. Anti-oxidant activity studies using nitric oxide and DPPH scavenging assay showed that the ethyl acetate and aqueous extracts could be promising sources of natural...
