China is one of the most important centers of diversity for Eriobotrya japonica Lindl. in the world. In this study, seven loquat cultivars grown in China were evaluated for their phenolic compounds and antioxidant activity. Eleven phenolic compounds, i.e., 3-p-coumaroylquinincacid (3-p-CoQA), 5-caffeoylquinic acid (5-CQA), 4-caffeoylquinic acid (4-CQA), 3-caffeoylquinic acid (3-CQA), 5-feruloyl...

Myricetin (Myc) is one of the most important flavonoids in diet due to its abundance in foods with the highest antioxidant activity. The antioxidant activity of Myc was studied in cell-free and cell-based systems to evaluate the ROS protection efficiency of Myc. The studies were based on the assessment of reducing power of Myc according to ferric ion reduction and intracellular ROS level measur...

background: potency test for control of rubella vaccine is a significant factor to qualify production line and vaccination pro­gram. for this reason, who recommends to use the microtitration method by both vaccine companies and control laborato­ries. then the study was done to improve this test. methods: three rubella virus samples, including an in-house standard, a lot of vaccine and an in- pr...

for evaluation the stability and potency of anthrax vaccine prepared in razi vaccine and serum research institute in iran, samples of different batches of vaccine were kept at 4-8 °c (refrigerator), 20-25 °c (room temperature) and 37 °c (incubator).the viable spores/ml of vaccines were determined using plate–counting method before and after holding at different temperatures monthly. vaccine pot...

mass vaccination against viral infections such as mumps is a very noticeable and appropriate attempt in common health. mumps infection has severe complications like deafness, infertility and meningitis. attenuated live vaccine of mumps is produced and used to prevent the problems. viral content in the monovalent vaccine is assayed with different methods. nowadays international standards introdu...

Polar extracts of Tapirira guianensis Aubl. were prepared for evaluation biological activities. Identification and quantification phenolic compounds, antioxidant activity, inhibition acetylcholinesterase enzyme antifungal potential performed in all extracts. High contents total phenols detected the ethanolic aqueous leaves (237.10±5.39 mg EAG/g 346.46±5.67 EAG) respectively. The same had a free...

objective: the role of herbs against the free radicals have been put forth recently in combating many diseases. the aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of tinospora cordifolia (setc). materials and methods: setcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (dpph), nitric oxide, hydr...
