The aims of this study were the evaluation of polyphenols and vitamin C content, and antioxidant capacity of dehydrated pulp powder and the dried flour obtained from the skin and seeds residue remaining after pulp preparation from camu-camu (Myrciaria dudia). Fifty-three different phenolics were characterised by HPLC-DAD-ESI-MS-MS and UPLC-HR-QTOF-MS-MS. The phenolic content of camu-camu flour ...

Mg-Al-LDH is a chemical compound produced through co-precipitation technique and modified with Cu(NO3)2.6H2O to form Mg-Al/Cu. However, the research on capability of these compounds for adsorbing mixtures cationic dyes as well malachite green (MG), methylene blue (MB), Rodhamine-B (Rh-B) has not been carried out. Therefore, this aims determine performance Mg-Al/Cu removing dyes. The materials u...

The present study is concerned with the evaluation of tannase and gallic acid production efficacy Bacillus licheniformis KBR6 under different environmental conditions through submerged fermentation. Results have shown that mineral sources differential influences on production. Highest yield was observed at incubation period 18 h 22 h, respectively. At tannic concentration 15 g/l, maximum cell mass...

Background: A renewed focus on medicinal mushrooms has brought forth a sustainable health dimension. Conventional strategies are insufficiently integrated with promotion. The health-promoting outcome of fascinated many groups during the past few years because various primary and secondary metabolites in different cellular components. They contain bioactive metabolites, including proteins (cytok...

In the group of chemical hepatocarcinogenic agents, the number of which has steadily increased in recent years (:$7), tannic acid deserves attention. Owing to its astringent effect, this compound was formerly used widely in therapy. The local treatment of thermal burns with tannic acid was suggested by Davidson (1935), and his procedure was generally employed in Hungary during World War II. I t...

Pomegranate (Punica granatum) peel is a nutritive, antioxidant rich byproduct, easily available after production of pomegranate juice and ready to eat arils. The present study is undertaken to know the nutritional importance of fresh and detanninated pomegranate peel powder. Fresh pomegranate peel collected after juice extraction from Bhagwa variety of pomegranate. Fresh peels were crushed fine...

Tannic acid inhibits the mutagenicity of several polycyclic aromatic hydrocarbons (PAHs) and their bay-region diol-epoxides. Our prior studies have shown that when applied topically to Sencar mice, tannic acid caused substantial inhibition of epidermal PAH metabolism, subsequent PAH-DNA adduct formation, and PAH-induced skin tumorigenesis (H. Mukhtar et al., Cancer Res., 48:2361-2365, 1988, and...

resistance of microencapsulated fish oil (mfo) in the rumen and its effects on fermentability of nutrients in the rumen was studied in 3 experiments. the key parameter in these studies was the amount of oil released from the microcapsules and their effects on gas production and rumen degradability in comparison with unprotected fish oil (fo). in the first experiment the effect of rumen and abom...

Cisplatin (cis-diamminedichloroplatinum (II) or CDDP), used in the treatment of many solid-tissue cancers, has its chief side-effect in nephrotoxicity. Hence, this study sought to investigate and compare the protective effect of gallic acid (GA) and tannic acid (TA) against cisplatin induced nephrotoxicity in rats. The rats were given a prophylactic treatment of GA and TA orally at a dose of 20...

Increasing evidence supports the hypothesis that tannic acid, a plant polyphenol, exerts anticarcinogenic activity in chemically induced cancers. In the present study, tannic acid was found to strongly inhibit tyrosine kinase activity of epidermal growth factor receptor (EGFr) in vitro (IC50 = 323 nM). In contrast, the inhibition by tannic acid of p60(c-src) tyrosine kinase (IC50 = 14 microM) a...
