The Inhibitory Effect of Haloxylon salicornicum on Contraction of the Mouse Uterus

Ethnobotanical, phytochemical and antimicrobial activity of Halexylon salicornicum (Ramth) as a graze and promising shrub against selected animal microbes

Folk medicine, including plants, has been utilized for humans and animals since the dawn of civilization. Because of the widespread problem of antimicrobial resistance around the world, one of the mainly significant challenges in microbiological research is to achieve a replacement antibiotic with the fewest adverse effects. Camel and ruminant grazing were provided by the wild shrub Halexylon salicornicum (Ramth). However, despite prior research demonstrating its antimicrobial action against human diseases, no investigations on its antimicrobial activity against animal pathogens have been conducted to far. The goal of this study is to investigate whether Halexylon salicornicum aqueous and solvent extracts have antimicrobial activity on a variety of animal pathogens isolated from cattle and poultry using the agar well diffusion method (Enterococcus faecium, Shigella flexneri, Bacillus Cereus, Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli, Streptococcus pyogens, Pseudomonas aerogenes, Salmonella typhimurium, and Candida albicans) moreover it's ethnobotanical and phytochemical. All of the extracts tested had antimicrobial efficacy against tested strains and included bioactive chemicals, particularly the acetone extract, had the highest antibacterial activity. As a result, it can be stated that Halexylon salicornicum is a promising important shrub that might be used as a natural antimicrobial alternative for animals or as a food additive.

Optimization of in vitro regeneration of Haloxylon salicornicum: a keystone species of extreme arid regions

Haloxylon salicornicum is an economically important perennial woody shrub of family Amaranthaceae and is a good source of food additives, fodder, fuel and nutrients in Indian Thar Desert. In vitro regeneration of H. salicornicum through nodal shoot segments is achieved in present investigation. Young green shoots in horizontal orientation were found to be more responsive than vertical orientation. Axillary shoot buds were activated on MS medium containing 10 µM BAP. Adventitious roots with intense root hairs were induced on horizontally placed shoots on half strength MS medium containing 2 µM NOA + 100 mg L^-1 activated charcoal. This is a first report on micropropagation of H. salicornicum. This protocol can be a useful means for in vitro characterization, mass propagation and conservation of the plant for future prospects.

Isolation and Characteristics of Biotechnologically Important Antagonistic Thermophilic Bacteria from Rhizosphere of Haloxylon salicornicum

Rhizobacteria are an active part of microbial population in the rhizosphere of plants. In this study, twenty rhizobacteria were isolated from the rhizosphere of a perennial grass, Haloxylon salicornicum, found in Cholistan desert, an arid landmass near Bahawalpur Pakistan, in one set of experimental conditions. Colony characteristics, biochemical and molecular analyses of these isolates were performed. All isolates were bacilli, gram positive with off-white colonies and exhibited typical bacilli colony morphology. None of the isolates was gelatinase, urease, indole, H2S and catalase producer. Eleven isolates were amylase producers and 8 isolates were acid producers. All isolates fermented glucose, 3 fermented lactose and 19 fermented fructose. Molecular data revealed that out of twenty isolates, 14 isolates showed 91-99% identity with Brevibacillus borstelensis, 4 with Bacillus subtilis (97-98%) and 2 with Bacillus licheniformis (94-99%) through BLAST analysis. All identified bacterial isolates cladded with their respective groups in the phylogenetic tree. Many (11-15 out of 20) of the isolates were more effective in inhibiting growth of the tested bacterial strains as compared to the positive control (Ampicillin 50 μg/disc). We conclude that bacilli are the predominant form populating rhizosphere of this desert grass. Among the isolated bacteria Brevibacillus borstelensis, Bacillus subtilis and Bacillus licheniformis are the most predominant species.

A review of hepatoprotective plants used in saudi traditional medicine

Liver disease is one of the major causes of morbidity and mortality across the world. According to WHO estimates, about 500 million people are living with chronic hepatitis infections resulting in the death of over one million people annually. Medicinal plants serve as a vital source of potentially useful new compounds for the development of effective therapy to combat liver problems. Moreover herbal products have the advantage of better affordability and acceptability, better compatibility with the human body, and minimal side effects and is easier to store. In this review attempt has been made to summarize the scientific data published on hepatoprotective plants used in Saudi Arabian traditional medicine. The information includes medicinal uses of the plants, distribution in Saudi Arabia, ethnopharmacological profile, possible mechanism of action, chemical constituents, and toxicity data. Comprehensive scientific studies on safety and efficacy of these plants can revitalise the treatment of liver diseases.
