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...

Water stress may affect the growth, physiology, morphology, biochemistry, and productivity of Nigella sativa (black cumin), a medicinal aromatic plant. Measuring these parameters under various irrigation regimes could provide useful information for successful genotype selection breeding. Therefore, agronomically significant features were evaluated in ten black cumin genotypes (Afghanistan, Paki...

Cumin leaf are medicinal plants that used as treatment and useful for health. contain secondary metabolites, one of which is flavonoids. Flavonoids the largest phenolic compounds found in function antioxidant, antibacterial, antiviral, anti-inflammatory, antiallergic, anticancer activities. The flavonoid content a plant can be affected by drying temperature manufacture simplicia. purpose this s...

A common problem with vegetable production in drought areas is low crop stand, but germination data are limited and inconsistent for cumin. Different priming methods positively affect the enhancement of seed seedlings growth, especially under stress conditions. The objective this study was to assess effects different treatment (unprimed seeds as control, hydro-priming, salicylic acid, jasmonic ...

cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...

in order to evaluate the different photoperiod and temperature sensitive pre-flowering phases in two cumin landraces a raciprocal transfer experiment from photoperiod 8 h to 16 h and vice versa under two different day/ night temperatures 20/10 and 30/20 ˚c was conducted. two model including ellis and adams were used to analyse the data and to quantify the duration of different developmental pha...

This study aimed to determine the effect of black cumin extract (Nigella sativa) on histopathological liver and kidneys in albino rats exposed organophosphates. used 20 male mice divided into five treatment groups, i.e. (K-) without organophosphate cumin, (K+) induced by 40 mg/kg BW, group BW as therapy (P1 ) 200 (P2) 400 (P3) 600 BW. Organophosphate administration for eight weeks seed was give...
