Comparative in vivo antidiabetic evaluation of leaves and bark of Berberis lycium Royle in alloxan induced diabetic rabbits

The aim of this study was to measure minerals in Berberis lycium leaves and bark to evaluate the effects of its methanolic extract on diabetic rabbits. For this study 15 female rabbits were used and were divided into five equal groups. For induction of diabetes in animals, Alloxan monohydrate was used. The animals were under […]

Thin layer chromatographic profiling and phytochemical screening of six medicinal plants in Bangladesh

Medicinal plants contain different bioactive compounds which have great importance to the health of individuals and communities. These compounds produce definite physiological action on the human body. The present study was carried out to verify the thin layer chromatographic (TLC) profiling and phytochemical screening of water and ethanol extracts of six different plant parts in […]

Endophytic Bacteria: A beneficial organism

Now a day due to this character they attain the keen interest of human. Wide variety of bioactive compounds are using in biotechnology are produce by these bacteria. They have ability to minimize […]

Indole acetic acid and flavonoids production by rhizospheric bacteria isolated from Medicago sativa L. rhizosphere

Rhizospheric region of the roots is richly supplied with the secondary metabolites that orchestrate all sort of rhizospheric interactions and hence communicate plant root with their below-ground competitors. A chemical dialogue is established between the microbes and plant roots that create an atmosphere of complex and dynamic interactions flourishing either symbiosis or pathogenicity. A wide […]

Comparison of morphological traits and essential oils content in Lippia citriodora L. cultivated in greenhouse and outdoor

Lippia citriodora L., Verbenaceae family, is cultivated due to useful secondary metabolites like essential oil compound, which apply in the food, cosmetics industries. This plant is used as decreasing blood sugar, anti-blood releasing of nose and enteral. There are a lot previous studied which investigated essential oil compound in Lippia citriodora in greenhouse or field […]

Chemical composition and insecticidal activity of essential oil of Artemisia herba alba (Asteraceae) against Ephestia kuehniella (Lepidoptera: Pyralidae)

Plant secondary metabolites play an important role in plant-insect interactions and therefore such compounds may have insecticidal or biological activity against insects. In the present study, aerial parts of Artemisia herba alba Asso were subjected to hydro distillation using a Clevenger-type apparatus and the chemical composition of the volatile oils was studied by GC-MS. Forty […]

Isolation and characterization of lovastatin producing fungi; investigating the antimicrobial and extracellular enzymatic activities

Lovastatin is the drug used to reduce blood cholesterol serum levels. The present study includes the isolation of new fungal species such as Aspergillus terreus to produce lovastatin and other key secondary metabolites that can be effectively used as antimicrobial agents. New strain was characterized by morphological and molecular identification. Lovastatin was produced by Aspergillus […]

Antimicrobial potential of the crude extracts of an ethno botanically important plant Quisqualis indica Linn.

The organic and inorganic crude extracts of different plant parts of Quisqualis indica Linn; were obtained by maceration technique in n-hexane, chloroform, ethanol and water. The phytochemical screening of the crude extracts disclosed the presence of a variety of secondary metabolites, such as alkaloids, tannins, saponins, terpenoids, flavonoids, cardiac glucosides and reducing sugars. The crude […]

Rapid seed DNA extraction for species identification and diversity analysis of Pumpkin

Cucurbita moschata an economically important species of the family Cucurbitaceae, shows high variability in fruit characteristics. A standardized DNA isolation protocol has been developed from dried pumpkin seeds for polymerase chain reaction for species identification and diversity analysis. Higher concentration of polysaccharides and polyphenols in pumpkin seeds interferes with DNA during its isolation resulting in […]

Chemical composition and bilogical effects of essential oil of Artemisia judaica an endemic plant from central Sahara of Algeria Hoggar

The medicinal plants contain many secondary metabolites that are gifted of different biologic activities as antiparasital, antimicrobial or antioxidant proprieties. Essential oil extracted from dried aerial parts of Artemisia judaica harvested at central Sahara of Algeria Hoggar, was analysed by gas chromatography (GC-FID) and coupled to mass spectrometry (GC-MS).  Thirty one compounds were identified, representing […]
