Determination of microbial degradability of N is important in formulating a sound supplementation strategy for efficient utilisation of basal as well as supplementary diet components. In vitro degradability of N (IVDN) from tannin-containing browses (Acacia cyanophylla, Acacia albida, Acioa barteri and Quercus ilex) and two herbaceous legumes (Desmodium intortum and Desmodium uncinatum) was det...

Lactobacillus plantarum is a lactic acid bacterium that can degrade food tannins by the successive action of tannase and gallate decarboxylase enzymes. In the L. plantarum genome, the gene encoding the catalytic subunit of gallate decarboxylase (lpdC, or lp_2945) is only 6.5 kb distant from the gene encoding inducible tannase (L. plantarumtanB [tanBLp ], or lp_2956). This genomic context sugges...

BACKGROUND Phytochemicals are found in abundance at different levels in many medicinal plants. It is important to measure the total phenolic compounds correctly in such medicinal plants, the better to assess their antioxidant capacity. METHODS Our study sought to evaluate the total phenolic, flavonoid, and tannin contents of three Algerian medicinal plants: Echium pycnanthum Pomel, Haloxylon ...

Olive oil can be considered as a functional food because they carry a number of beneficial effects on the organism beyond nutritional benefits accepted. Studies conducted so far have shown that phenolic compounds in olive oil have positive effects on various physiological biomarkers, while exhibiting high bioavailability. Experimental studies (in vivo and in vitro) on phenolic compounds in oliv...

The underutilized fruits Baccaurea ramiflora (Kusum) from the eastern region of India were investigated for nutritional composition, phytochemicals and bioactive compounds. A detailed nutritional characterization of the fruit demonstrated that it has the potential to act as good source of minerals along with other nutrients, dietary fibres, significant phenolic compounds and possesses antioxida...

Consumption of tomato fruits, like those of many other plant species that are part of the human diet, is considered to be associated with several positive effects on health. Indeed, tomato fruits are an important source of bioactive compounds with known beneficial effects including vitamins, antioxidants, and anticancer substances. In particular, antioxidant metabolites are a group of vitamins,...

Olive oil is considered to be one of the most healthy dietary fats. However, several types of olive oils are present in the market. A key question for the consumer is: What of the olive oils is the best when concerning nutritional purposes? With the data available at present, the answer is: the Virgin Olive Oil (VOO), rich in phenolic compounds. On November 2011, the European Food Safety Author...

the drastic decline of precipitation over the past decade along with overuse of chemical inputs and consequent soil fertility reduction are the most important problems in the approach to agricultural expansion, particularly in urban landscaping. therefore, an experiment was designed to examine the effects of different irrigation levels (40, 70 and 100 % of field capacity, or fc) and different v...

The performance of hybrids depends upon the inheritance and expression of resistance traits. Secondary chemicals are one such resistance trait. In this study, we measured the concentrations of phenolic glycosides and condensed tannins in parental and F1 hybrid willows to examine the sources of chemical variation among hybrids. S. sericea produces phenolic glycosides, salicortin and 2'-cinnamoyl...

Extending the knowledge on secondary metabolites and the effect of solvent of extraction in mushrooms, We investigated five mushrooms species; two cultivated edible (Agaricus bisporus (brown) and Agaricus bisporus (white); and three wild medicinal edible mushrooms Trametes versicolor, Ganoderma applanatum and Fomes fomentarius for total phenolic, total flavonoid and condensed tannins content. T...
