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...

Nowadays, the use of essential oils as alternative therapies has gained worldwide concern, owing to their various biological activities. Considerable attention has been devoted to essential oil, which is widely used for its important properties, including antimicrobial, anti-inflammatory, antispasmodic, cytoprotective, hepatoprotective, with strong antioxidant actions. Eucalyptol is an essential oil present in large amounts in a variety of plants, which is frequently used in the manufacture of cosmetics, to increase percutaneous penetration of drugs, as a nasal decongestant and anti-cough agent, and in aromatherapy. GC analysis of the essential oil was carried out on the Agilent 7820A system with a mass detector (MS) and a HP-5 MS column (30 m × 0.25 mm, 0.25 μm film thickness). Nineteen essential chemical constituents were identified based on GC-MS in Eucalyptus oil supplied from the pharmacy. The main constituents of Eucalyptus oil are eucalyptol (76.81%), γ -terpinene (7.75), α-pinene (6.62), and α-terpineol (1.44%). These four components account for 92.6% of the total relative content of the Eucalyptol oil. This research also demonstrated...

Acne is a skin-related condition entailing many psychological complications. Although several medications have been developed, natural remedies attracted more attention because of the less side effects and multifunctional. The objective of this study was to prepare and evaluate the anti-acne effects of a pharmaceutical gel containing herbal extracts, including Lawsonia inermis and Matricaria chamomilla. The total phenolics of extracts were determined with the Folin-Ciocalteu method. Using Hydroxypropyl methylcellulose (HPMC), carboxymethyl cellulose (CMC) and propylene glycol (PEG), the pharmaceutical gel was formulated and the physical properties of the formulation were specified at 37 ± 2 °C. The release of the active ingredients from the optimum formulation was investigated using Franz cell device. The results showed that the optimum formulation was stable at least for 3 months. The total phenol content of the aqueous extract of Henna leaves, hydroalcoholic extract of chamomile flowers, and the optimum formulation was 57.8 mg/g ex, 181.08 mg/g and 202.75 mg/g, respectively. Nearly 80 % of the phenolic compounds in the optimum formulation were released over...
