Antioxidant Activity of Hepatoprotective Silymarin and Silybum marianum L. Extract
The paper presents the antioxidant activity evaluation of Silybum marianum L. extract in comparison with the commercial silymarin standard solution (2 mg/mL) and the time-dependent antioxidant capacity by calculating the free radical 2,2-diphenyl-1-pycryl-hydrazyl (DPPH) reaction rate in the presence of these biosystems. The best result was obtained in the case of S. marianum L. extract, with a...
متن کاملIn vitro antioxidant activity of berry (Morus alba var.nigra)
Antioxidant activity of Berry (Morus alba var. nigra) was investigated. For superoxide anion radical assay, the superoxide anion radicals were generated by a pyrogallol auto oxidation system, Nitric oxide radical inhibition by the use of Griess Illosvoy reaction and reducing power was determined according to the Oyaizu method. At least this sample was represented a potential antioxidant capacit...
متن کاملUltrasonic-assisted enzymatic extraction of silymarin from the Silybum marianum seed shell and evaluation of its antioxidant activity in vitro
This study revealed the optimal conditions for the Ultrasonic-Assisted Enzymatic Extraction (UAEE) of silymarin, and include: the concentration of ethanol, 50 %; enzyme concentration, 30 U/mg; liquid-solid ratio, 6:1; an extraction time of 120 min; and the ultrasonic power at 180 W. The extraction rate was 7.86 %, which is higher, by 74.67 %, than that of the silymarin extract from the Silybum ...
