Humans consume a wide range of foods, drugs, and dietary supplements that are derived from plant extracts and which modify the functioning of the central nervous system (CNS). Some drugs from plant extract. Plant extracts is our human friends.

Ninety male Holstein bulls were used in a complete randomized design to study the effects of a blend of plant extract (PE: cynarin, gingsen and fenugreek; Biostar?, Phytosynthese, France) supplementation on performance, rumen fermentation, and metabolism of Holstein bulls fed high-concentrate diets.

In many cases, the effects of these phytochemicals on the human CNS might be linked either to their ecological roles in the life of the plant or to molecular and biochemical similarities in the biology of plants and higher animals.

Biosensors represent an interesting tool in the search of bioactive compounds. In particular, optical sensors based on Surface Plasmon Resonance transduction (SPR) allow monitoring of biomolecular interaction in real time and without any labelling of the interactants. The biosensor analysis can be applied to both pure compounds or to complex ...
... mixtures.

Saponins also have selective antibacterial effects that may prove useful in, for example, controlling starch digestion. The 'Rumen-up' project began with a targetted collection of European plants and plant extracts, which partners have tested for their effects on rumen proteolysis, protozoa, methanogenesis and lactate production.

White plant extract is a natural source that effectively inhibits adipogenesis and stimulates lipolysis-activity. Therefore, it can be utilized to modulate different levels of the adipocyte life cycle.

For this purpose, we chose four independent potato genotypes characterized by modifications in sucrose metabolism. Plant extraction analysis allowed identification of the most important components of these clusters. Furthermore, correlation analysis revealed close linkages between broad spectrums of metabolites.

The aqueous plant extract of the leaf mixtures of Aloe buettneri, Dicliptera verticillata, Hibiscus macranthus and Justicia insularis given by oral route to immature female rats, at doses of 13, 49 and 94 mg/kg per day for 15 days induced a significant increase in ovarian and uteri weight as well as serum and ovarian oestradiol. Moreover, a significant decrease in liver of aminopyrine N-demethylase activity was noticed in treated animals.

Adequate intake of specific phytochemicals can increase adaptive responses regulating hormone metabolism and cell behavior. Cruciferous vegetables, cabbage, cauliflower, and broccoli, posse unique phytochemical constituents able to modify the metabolism of oestrogen.

In summary, these data demonstrate the use of metabolic profiling in conjunction with data-mining tools as a technique for the comprehensive characterization of a plant genotype.
