Objectives: Evaluation of antihyperglycemic activity of aqueous extract of leaves of Solanum nigrum (AELSN) in Alloxan induced diabetic rats. Comparison of antihyperglycemic activity of aqueous extract of leaves of Solanum nigrum with standard drug Glimepiride. Methodology: 200-250 g of Wistar rats of either sex were divided into 4 groups (n=6). Group l is normal control (received 0.5ml normal ...

OBJECTIVE To investigate the in vitro antioxidant activity of different fractions (R1, R2 and R3) obtained from pet ether extract of black pepper fruits (Piper nigrum Linn.) MATERIALS AND METHODS The fractions R1, R2 and R3 were eluted from pet ether and ethyl acetate in the ratio of 6:4, 5:5 and 4:6, respectively. 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) radical, superoxide anion radical, nitri...

Plants used in popular diet were studied for anti-Helicobacter pylori activity and their effect on the expression of interleukin-8 (IL-8) from H. pylori infected gastric epithelial cells. Extracts were prepared of Allium sativum (A. sativum), Cuminum cyminum (C. cyminum), Piper nigrum (P. nigrum) and their mix in two different dilutions. AGS cell line and H. pylori strains were used for co-cult...

The exotic vines Vincetoxicum rossicum (Kleopow) Barbar. and Vincetoxicum nigrum (L.) Moench have become increasingly invasive in lowand high-light habitats in North America, and a biological control program is being developed. These plants experience little damage in North America, so it is unclear how they might respond to introduced herbivores. I conducted an artificial defoliation study on ...

Little is known about the number and rate of introductions into terrestrial and marine tropical regions, and if introduction patterns and processes differ from temperate latitudes. Botryllid ascidians (marine invertebrate chordates) are an interesting group to study such introduction differences because several congeners have established populations across latitudes. While temperate botryllid i...

BACKGROUND The blackcurrant (Ribes nigrum L.) is a species of native currant which contains a lot of polyphenolic antioxidants which is used medicinally and has a fundamental role in the maintenance health. MATERIALS, METHODS AND OBJECTIVE: Ultraviolet-visible spectrophotometry and ultraviolet range high performance liquid chromatography (HPLC) were used to characterize the polyphenolic content...

Background: Over the past few decades, there has been more interest in geminiviruses, especially begomoviruses, as many of the diseases they cause have now reached epidemic proportions. Weed plants serve as an alternative host for begomoviruses and may allow the transmission of begomovirus to other horticulture crops and medicinal plants thus enhances the host range of these viruses in differen...

Indian spices that provide flavor, color, and aroma to food also possess many therapeutic properties. Ancient Indian texts of Ayurveda, an Indian system of medicine, detailed the medicinal properties of these plants and their therapeutic usage. Recent scientific research has established the presence of many active compounds in these spices that are known to possess specific pharmacological prop...

The effects of salt stress (100, 200, 300 mmol/L) on physiological characteristics Solanum nigrum seedlings were studied by pot experiment. results showed that the contents chlorophyll a, b, carotenoids and total in S. leaves a trend first flattening then increasing with aggravation stress. With stress, net photosynthetic rate, stomatal conductance intercellular CO2 concentration decreased grad...
