Comprehensive comparison of antioxidant activity bioactive peptides produced from fish, poultry and shrimp wastes using Flavourzyme enzyme

Garcinia atroviridis (Clusiaceae) has been used as a postpartum medication agent in folkloric medicine. However, its biological potential has not been fully evaluated. The present study was aimed to evaluate the antioxidant efficacies, cholinesterase enzyme inhibitory and antimicrobial activity of the stem bark extracts of G. atroviridis. Successive extraction was done using solvents of varied ...

background: withania somnifera l. dunal, (ashwagandha) belongs to the family solanaceae and is known as ‘indian ginseng’ in the traditional system of medicine. objectives: in the present investigation, comparative analysis was carried out between two different ecotypes of w. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (cat), superoxide dismutase (sod) an...

in order to optimization of protein hydrolysis condition (including enzyme to substrate ratio (e/s), temperature and time) for achieving the highest antioxidant activity, the green tiger prawn (p. semisulcatus) mince was tested via commercial protease (alcalase® 2.4l) based on the response surface designed method in 18 treatments and then dried to obtain powder in freeze dryer. the antioxidant ...

the present study investigated the effects of e. coli lipopolysaccharide (lps) induced mastitis model in rat on the activity of antioxidant enzyme systems. to achieve this purpose, e. coli lps were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. the antioxidant activ...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

to determine the importance of q 10 h 2 as an antioxidant in cancer, we measured the activity of lipoamide dehydrogenase (q 10 h 2 recycling enzyme) in hl-60 and normal lymphocyte. the cultured cells of hl-60 and human normal lymphocytes were assayed in cell lysate of given number of both hl-60 and normal lymphocyte. the activity of lipoamide dehydrogenase and the protein concentration were det...

abstract: in a wide search program towards new and efficient antimicrobial agents, a series of 4-substituted-1,2,4-triazolidine-3,5-dione derivatives namely urazoles holding an alkyl moiety at position 4 have been synthesized and tested for their in vitro antibacterial and antifungal activities. the structures of these compounds have been investigated by spectral data. the synthesized compounds...
