Oak trees cover a wide range of forests in Iran and most of them are located in Kohgiloye and Boyer-Ahmad province (K.B). The high tannin is one of the anti-nutritional characteristics of acorn for domestic animal. Wide range of gut microorganisms could tolerate tannin and reduce it by producing tannase enzyme. This study was carried out to isolate and identify the tannin resistance bacteria (t...

Green tea (Camellia sinensis) is one of the most widely consumed beverages in the world. The cancer chemopreventive qualities of green tea have been well documented. Epigallocatechin gallate (EGCG) is often described as the most potently chemopreventive green tea catechin; however, the low bioavailability of EGCG is a limiting factor for its biological effect. Thus, the aim of this work was to ...

Eleven fungal strains (4 Penicillium commune, 2 Aspergillus niger, 2 Aspergillus rugulosa, Aspergillus terricola, Aspergillus ornatus and Aspergillus fumigatus) were isolated, characterized morphologically and by their capacity to degrade tannins. Aspergillus niger Aa-20 was used as control strain. Several concentrations of hydrolysable tannin (tannic acid) were used as sole carbon source. All ...

• EAEP increased extractability and bioaccessibility of soy isoflavone aglycones. phenolic compounds. resulted in extracts with higher antioxidant potential. improved the functional biological properties extracts. The effects enzymatic extraction strategies on extractability, bioconversion, biologically active aglycones, total content, activity aqueous from full-fat flour were evaluated. Protea...

For the purpose of discovering natural products which possess hair growing activity, we examined about 1000 kinds of plant extracts concerning growth-promoting activity with respect to hair follicle cells. After an extensive search, we discovered that proanthocyanidins extracted from grape seeds promote proliferation of hair follicle cells isolated from mice by about 230% relative to controls (...
