Antimicrobial growth promoters (AGPs) have been banned and phased out because their use has been linked to the emergence and spread of antibiotic-resistant pathogens; however, the ban has had a marked impact on livestock production, and feed additive alternatives to AGPs are required. We focused on green tea leaves as potential alternatives to AGPs because they contain significant amounts of po...

We describe three patients who worked in green tea factories and developed asthmatic and nasal symptoms after exposure to green tea dust. To clarify what component(s) of green tea leaves might be responsible for causing asthma, we prepared catechins, the major components of green tea leaves. Epigallocatechin gallate (EGCg; MW: 458 daltons), a major catechin, was purified by high-performance liq...

Effects of kaolin applicati on were evaluated on water stress in pistachio cv. ‘Ohadi’. This experiment was conducted in one of research sites at the Pistachio Research Institute in Rafsanjan (Kerman province) in . The results show that individual and interaction effects of all treatments were significant on nutrition absorption in leaves, although there was not a steady effect on all the eleme...

in order to transfer rhizomania resistance genes to improved sugar beet lines, crosses were made between 11 commercial resistant varieties and two improved inbred o-type lines of sugar beet (231 and 261) at agricultural research center of khorasan razavi   and jam sugar factory in 2007. o-types carried self fertile (sf) genes and contained male sterile (ms) genotypes. commercial varieties were ...

Jatropha curcas leaves extract was tested as a green corrosion inhibitor for mild steel in aqueous hydrochloric acid solution using gravimetric and thermometric techniques. The results reveal that the inhibition efficiency vary with concentration of the leaf extract and the time of immersion. Maximum inhibition efficiency was found to be 95.92% in 2M HCl with 0.5 g/l concentration of the extrac...

The white leaf tissue of seedlings of Zea mays L. affected by the recessive nuclear gene iojap shows no photosynthetic activity; it contains about 1.4% of carotenoid and less than 0.1% of chlorophyll a content of normal green tissue. Neither fraction I protein nor chloroplast adenosine triphosphatase (EC 3.6.1.4) (CF(1)) is detectable. This confirms earlier observations that plastids of white s...

Tea is the most widely consumed beverage in the world. Tea leaves are a source of polyphenols, especially catechins, a decisive group for their antioxidative activity. This paper reviews what is known of green tea species, its leaves processing and changes occurring in tea components. The main green tea polyphenols are catechins: (±)-catechin C, (-)-epicatechin EC, (+)-gallocatechin GC, (-)-epi...
