Anethum graveolens was characterized by scanning electron microscopy and elemental analysis. The ability of Anethum graveolens to adsorb Pb(II) was investigated by using batch adsorption procedure. The effects such as pH, contact time, adsorbate concentration and biosorbent dosage on the adsorption capacity were studied. The experimental data were analysed using various adsorption kinetic models viz., the pseudo-first and second-order equations, Bangham’s equation, intraparticle diffusion and Elovich models. Results show that the pseudo-second-order equation provides the best correlation for the biosorption process. The equilibrium nature of Pb(II) adsorption at 30℃ has been described by the Langmuir, Freundlich, Temkin and Redlich-Peterson isotherm models. The equilibrium data fit well on Langmuir isotherm. The monolayer adsorption capacity of Pb(II) onto Anethum graveolens as obtained from Langmuir isotherm at 30℃ was found to be 303 mg/g. This high adsorption capacity of Anethum graveolens places this biosorbent as one of the best adsorbents for removal of Pb(II) from aqueous effluents.展开更多

Methods: In this descriptive study, the antioxidant and antiradical properties of dill tablet at dif erent concentration(0.032, 0.065, 0.125, 0.25, 0.5 and 1 mg/m L) were measured. The total phenolic, l avonols and l avonoid, alkaloids, anthocyanin, tannin and saponin contents in dill tablet were determined. Furthermore, antiglycation properties of dill tablet were assayed. In the in vivo experiments, male rats were randomly divided into three groups(n = 6): Group 1: normal rats; Group 2: diabetic rats; Group 3: diabetic rats + 300 mg/kg dill tablet, and Group 4: diabetic rats + 100 mg/kg dill tablet. After 2 months, the blood glucose was measured enzymatically and advanced glycation end-products(AGEs) formation was determined using a l uorometric method.Results: Our results illustrated that different concentrations of dill tablet had significant antioxidant activity. Dill tablet markedly declined AGEs formation and fructosamine levels(P < 0.001) compared with glycated sample. Oxidation of protein carbonyl and thiol group was signii cantly reduced by dill tablet in a dose dependent manner(P < 0.001). Formation of amyloid cross-β and fragmentation were markedly inhibited by dill tablet(P < 0.001) compared with glycated sample. After 2 months, fasting blood glucose levels(P < 0.001) and AGEs formation(P < 0.05) were signii cantly reduced by dill tablet in diabetic animals. Conclusions: Dill tablet exhibited significant antiglycation and antioxidant activities. This study provides a scientii c basis for using dill in treatment of diabetic patients.展开更多
