B.Umamaheswari & S.Rajalakshmi – Department of Microbiology, Idhaya College for women Kumbakonam. Guided by: Miss. B.Umamaheswari, M.Sc., M.Phil,-lecturer in microbiology, Idhaya College for women ABSTRACT In the present study the Indian spices extracts of Piper nigrum, Foeniculum vulgare, Syzyigum aromaticum and Elettaria cardamomum was used for antibacterial activity assay. The test organism ...

This study focused on the protective actions of Empetrum nigrum against ultraviolet B (UVB) radiation in human HaCaT keratinocytes. An ethyl acetate extract of E. nigrum (ENE) increased cell viability decreased by exposure to UVB rays. ENE also absorbed UVB radiation and scavenged UVB-induced intracellular reactive oxygen species (ROS) in HaCaT keratinocytes. In addition, ENE shielded HaCaT ker...

Solanum nigrum (European Black Nightshade or locally just "black nightshade", present in the flora of Europe, Serbia. It grows in different types of habitats like as weed, in crops, ruderal habitats, along the roads, fences and neglected places. They are semi cultivated in most countries and largely utilized as a vegetable and fruit source. Solanum nigrum has very much importance as a medicinal...

N the course of some research on peppers, Capsicum annum (SMITH and I HELSER 1951 ) , conducted at the Citrus Experiment Station, Riverside, California, several striking, heritable fruit characters were noted. Upon further analysis, a chromosome linkage was found to exist between two immature-fruit color genes and a gene determining pepper fruit shape. In addition the fruit shape difference bet...

Effects of varying temperatures with constant pressure of solvent on extraction efficiency of two chemically different alkaloids were studied. Camptothecin (CPT) from stem of Nothapodytes nimmoniana (Grah.) Mabb. and piperine from the fruits of Piper nigrum L. were extracted using Accelerated Solvent Extractor (ASE). Three cycles of extraction for a particular sample cell at a given temperature...

Globally available folklore medicines are consumed by people as food, without scientific validation. Aim of the present study is to evaluate the antiulcer and antioxidant activity of traditional herbs. Physicochemical analysis, preliminary phytochemical analysis and quantitative analysis of aerial parts from Solanum nigrum and Cynodon dactylon were carried out. the free radical scavenging activ...

In a previous study, we demonstrated that transgenic Lotus plants producing opines (which are small amino acid and sugar conjugates) specifically favor growth of opine-degrading rhizobacteria. The opine-induced bias was repeated and demonstrated with another soil type and another plant species (Solanum nigrum). This phenomenon is therefore independent of both soil type and plant species.

Bioactive substances are responsible for therapeutic properties of the plant in folk medicine. They have actions body that may promote good health. being studied prevention disease. The present investigation is focused on screening bioactive various parts (leaves, stems, and grains) Solanum nigrum. Qualitative tests presence phytochemicals different extracts using solvants with polarity such as...

Goal. Determine the species composition of weeds, their dominant role and establish type level weediness winter wheat crops by cultivation on black fallow, after peas for grain as forecrops in Eastern Forest-Steppe Ukraine.
 Methods. The research was carried out means route surveys field experiments located a stationary nine-field steam-grain-row crop rotation monoculture wheat.

North East India is one of the mega biodiversity hot spot, also one of the richest reservoir of genetic variability and diversity of different crops. Here, natural distribution of non tuberous Solanum species is also found to be very rich. Despite the importance of Solanum species no information in the karyotype of the members of this taxa available in North East India is found. In the present ...
