Acute renal failure (ARF) is a life-threating disease with high mortality percentage. Two important mechanisms of ARF are inflammation and oxidative stress. Plants are rich source of antioxidant compounds and have a strong anti-inflammatory activity, so they may be useful for the treatment of ARF. Some herbal medicines are effective against different models of experimentally induced ARF such as cisplatin, gentamicin, glycerol, and ischemia-reperfusion injury. Some of these plants such as ginseng, black seed, ginger, garlic, grape, pomegranate, saffron, and green tea are so famous and are effective against various models of ARF...

Black garlic produced from fresh garlic under controlled high temperature and humidity has strong antioxidant properties. To determine these compounds, five fractions (from F1 to F5) were separated and purified by elution with chloroform:methanol at different ratios (8:1, 6:1, 4:1, 2:1, and 0:1; v/v). The antioxidant activity of each fraction was analyzed. The results showed that F3 and F4 had higher phenolic contents and stronger 2,2-diphenyl-2-picrylhydrazyl radical scavenging activity than the others. Seven purified individual components were further separated using semipreparation high-performance liquid chromatography from these two intensely antioxidant fractions (F3 and F4), their structures were elucidated by high-performance liquid chromatography coupled to diode array detection, electrospray ionization, mass spectrometry,1 H nuclear magnetic resonance, and13 C nuclear magnetic resonance spectrometry...

Black garlic is obtained from fresh garlic (Allium sativum L.) that has been fermented for a period of time at a controlled high temperature (60-90°C) under controlled high humidity (80-90%). When compared with fresh garlic, black garlic does not release a strong offensive flavor owing to the reduced content of allicin. Enhanced bioactivity of black garlic compared with that of fresh garlic is attributed to its changes in physicochemical properties. Studies concerning the fundamental findings of black garlic, such as its production, bioactivity, and applications, have thus been conducted...
