the effect of ethanolic extract of iranian green propolis, rosemary and earthworm meal to determine on performance, immune system and blood metabolites of japanese quail, using 160 mixed-sex quail chicks in a completely randomized design by four treatments (including ethanolic extract of propolis 0.1 percent, rosemary leaves meal 0.5 percent, earthworm meal 0.5 percent and control) and four rep...

Four triterpenes were isolated from a traditional Japanese tea product produced by anaerobic microbial fermentation of heated green tea leaves (Camellia sinensis). Two of the compounds were novel and characterized by spectroscopic investigation to be 13,26-epoxy-3β,11α-dihydroxyolean-12-one and 3β,11α,13β-trihydroxyolean-12-one. Two known triterpenes were identified as taraxastane-3β,20β-diol a...

Trees can improve air quality, but at the same time, pollution might put them at risk. Plane(Platanus orientalis L) and willow trees (Salix babylonicaL) are important trees in the green space of Tehran. Plane trees in Tehran have experienced early autumn in recent years due to severe air pollution. The present study, investigated some physiological traits of these trees under study to determine...

Several papers have appeared in the literature since 1992 which refer to a major "isoflavonoid" antioxidant in young green barley leaves (Hordeum vulgare) as 2''-O-glucosylisovitexin. In the present paper the original NMR data supporting this structural assignment are examined and found to have been misinterpreted. HPLC and NMR data are used to prove that the major flavonoid antioxidants in you...

Shoot growth, chlorophyll concentrations, gas exchange and starch concentrations were studied in lychee (Litchi chinensis Sonn.) seedlings of cultivar "Wai Chee" grown in a heated greenhouse at Nambour in subtropical Australia (27 degrees S). We also examined the effects of shoot defoliation and root pruning on leaf expansion. Shoot growth showed a rhythmic cycle under constant greenhouse condi...

Alloplasmic lines of Brassica napus with rearranged Arabidopsis thaliana mitochondrial DNA are male sterile and vegetatively altered compared with B. napus cv. Hanna. The CMS lines contain pure nuclear and plastid genomes from B. napus. Cross-sections of leaves revealed elevated starch accumulation and a higher number of chloroplasts per cell area in CMS plants compared with B. napus. The incre...

Mechanisms restricting the accumulation of chloroplast glycolipids in achlorophyllous etiolated or heat-treated 70S ribosome-deficient rye leaves (Secale cereale L. cv "Halo") and thereby coupling glycolipid formation to the availability of chlorophyll, were investigated by comparing [(14)C]acetate incorporation by leaf segments of different age and subsequent chase experiments. In green leaves...
