The model reaction was first carried out in absence of catalyst in water the reaction was not gave desired product even after prolonged reaction time, then we employed different catalysts for model reaction some catalysts (Table l) can catalyze this reaction with moderate yields but we found that using tannic acid
the desire product formed with higher yield that is 96% yield within 45 minutes (Table l, entry 9).
Among the variables tested, the statistically significant variables (p < 0.1) were tannic acid
, potassium nitrate and incubation time.
In ad- dition to growth in the oral cavity Candida albicans can ferment and/or assimilate some dietary sugars and produce organic acids in dental plaque.14 The pur- pose of the present study was to determine the effect of Tannic Acid
on the growth and acid production of Candida albicans.
The samples' tannic acid
levels totaled 0.25, 0.5, 1.0 and 2.0 milligrams (mg) per milliliter of peanut butter extract.
For the study, Chung mixed four different levels of tannic acid
in peanut butter extract.
Furthermore, histopathology study revealed normal glomerulus and tubules with intact renal architecture in normal (Figure 3(a)), gallic (Figure 5(a)), and tannic acid
(Figure 5(b)) group without cisplatin injection.
The results show that as the quantity of tannic acid
is increased, first the size decreases and then reaches saturation.
Recently, reduction of metal salts by tannic acid
has attracted attention of scientific community since it fulfils the requirement of a chemical reductant, but itself is a plant derived compound.

Caption: Mix iron and tannic acid
in water and they'll bond, forming little capsules (shown).
Figure 4 presents the percentage of remaining DPPH ([DPPH.sub.R] as a function of the concentrations of EELB, ascorbic acid and tannic acid
. Ascorbic acid was selected for its common use in the food industry, and tannic acid
for being reported as a metabolite present in the EELB.
Massachusetts Institute of Technology (MIT) engineers developed a nanoscale biological coating that consists of two alternating layers of thrombin, a natural clotting protein, and tannic acid
, a small molecule found naturally in tea, which yields a film containing large amounts of functional thrombin.
