Background Thymoquinone is one of the active ingredients of black cumin (Nigella sativa L.) essential oil possessing antiinflammatory, antineoplastic, neuroand hepatoprotective properties. Some of these properties were attributed to an antioxidant activity of thymoquinone, which seems to be unlikely from its structure. Because the lipophilic thymoquinone exhibits a structural similarity with th...

Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger cause...

The loss of the ability for learning and memory is a prominent feature of dementia, which affects millions of individuals all over the world, due to either neurodegenerative diseases or brain injury. Although a lot of information is known about the pathology involved, treatment remains elusive at best. The Black Seed of Nigella sativa has been historically and religiously used for thousands of ...

Metronidazole (MTZ) was the most widely accepted treatment for Blastocystis hominis (B. hominis) with high treatment failure rate, resistance and potential mutagenic and carcinogenic effects so there is urgent need to find out new, effective and safe treatment against B. hominis. The present research aimed to evaluate the therapeutic effect of the aqueous extract of Nigella sativa (NS) at diffe...

The present study was conducted to find out the antibacterial activity of aqueous and organic extracts of Nigella sativa (L.) seeds against various bacterial pathogens, namely; S. aureus, P. aeruginosa and E. coli. Plant extract along with different elicitors such as metal ions and commercial drugs was also screened to see the change in efficacy and potency of the compounds. Among different ext...

it has been reported that several members of convolvulaceae family such as convolvulus arvensis possess cytotoxic activity on some tumor cell lines. proteoglycan mixture, the water extract of c. arvensis with high molecular weight, has potent anti-angiogenesis and stimulating effects. in this study, arial parts of c. arvensis were collected and identified, and the cytotoxic effects of chlorofor...

Our previous studies have demonstrated the relaxant, anticholinergic (functional antagonism), antihistaminic, and inhibitory effect of calcium channels of Nigella sativa on guinea pig tracheal chains. To investigate the other mechanism responsible for the relaxant effect of this plant, the stimulatory effect of Nigella sativa on ß 2 -adrenergic receptors in tracheal chains of the guinea pig was...

Nigella sativa (NS) has been shown to have antioxidant, anti-inflammatory and antiulcer activities in different conditions. The present work was done to investigate the possible effects of Nigella sativa aqueous extracts (NS) on gastric acid secretion in isolated rat stomach. Gastric acid secretion was measured in the isolated rat stomach preparation. The results obtained in vitro experiments s...

Many herbaceous perennial plant species gain significant competitive advantages from their underground creeping storage and proliferation organs (CR), making them more likely to become successful weeds or invasive plants. To develop efficient control methods against such weedy plants, it is necessary identify when the dry weight minimum of CR (CR DWmin) occurs. Moreover, interest determine how ...

Medicinal plants are now widely used for various purposes, such as preventing and treating diseases. One of the medicinal traditional medicines already commercialized is Sonchus arvensis, known show thistle tempuyung in Indonesia. This mini-review will highlight information about uses, phytochemical compounds, biological activities S. arvensis to increase our knowledge understanding this plant....
