BACKGROUND All plants in nature harbor a diverse community of endophytic bacteria which can positively affect host plant growth. Changes in plant growth frequently reflect alterations in phytohormone homoeostasis by plant-growth-promoting (PGP) rhizobacteria which can decrease ethylene (ET) levels enzymatically by 1-aminocyclopropane-1-carboxylate (ACC) deaminase or produce indole acetic acid (...

We report, for the first time, the remarkable efficacy of uttroside B, a potent saponin from Solanum nigrum Linn, against liver cancer. The compound has been isolated and characterized from the leaves of Solanum nigrum Linn, a plant widely used in traditional medicine and is a rich resource of several anticancer molecules. Uttroside B, that comprises of β-D-glucopyranosyl unit at C-26 of the fu...

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...

Efficient plastid transformation has been achieved in Nicotiana tabacum using cloned plastid DNA of Solanum nigrum carrying mutations conferring spectinomycin and streptomycin resistance. The use of the incompletely homologous (homeologous) Solanum plastid DNA as donor resulted in a Nicotiana plastid transformation frequency comparable with that of other experiments where completely homologous ...

The efficacy of extracts from two Piperaceae species, Piper nigrum L. and P. tuberculatum Jacq. were evaluated using larvae and adults of the Colorado Potato Beetle Leptinotarsa decemlineata (Say). Young larvae and neonates were the most susceptible; a 24-h LD(50) of 0.064% extract of P. tuberculatum was determined for 4-day-old larvae, while 0.05% extract of P. nigrum reduced larval survival u...

BACKGROUND Solanum nigrum is claimed in traditional medical practice, to be useful in the treatment of epilepsy in some parts of Nigeria. OBJECTIVES To study the anti-convulsant property of the aqueous extract of the leaves of S. nigrum in chicks, mice and rats. METHOD Aqueous extracts were administered intraperitoneally, at a pre-treatment time of 30 minutes, at graded doses and animals we...

Solanum nigrum Linn. is extensively used in Indian traditional and folk medicines to cure various skin ailments. The present study aims to evaluate the possibility for the presence of novel bio-active compounds against fungal pathogens. To determine antifungal activity, aqueous and crude extracts from leaves of S. nigrum Linn. was used against A. niger, A. flavus, C. albicans by dry weight meth...

Root extracts of black nightshade (Solanum nigrum) were analyzed for activity against isolates ABA-31 and ABA-104 of Alternaria brassicicola, the causal agent of black leaf spot of Chinese cabbage (Brassica pekinensis). Preliminary results showed that dried root tissues of black nightshade extracted with 70% ethanol contained antifungal properties against A. brassicicola. Ethanol root extracts ...
