Figure 1 Figure 2 Citrus fruits are traditional agricultural products in Egypt. Citrus volkameriana is the best rootstock for growing citrus in Egypt’s desert areas (newly reclaimed land). It is far superior to other rootstocks used in Egypt in its resistance to Citrus tristeza virus as well as its tolerance to drought. Constraints to fruit production are mainly related to tree decline caused b...

The lack of robust measures of dietary exposure hinders a quantitative understanding of causal relationships between diet and health. Non-targeted metabolite fingerprinting was used to explore the relationships between citrus exposure in free-living human subjects, estimated by a FFQ, and the chemical content of urine. Volunteers (study 1, n 12; study 2, n 11) were classified into high-, medium...

Three metabolites appearing in the urine of animals after the ingestion of the flavonol quercetin (1, 2) having been identified, our interests were next centered on similar studies of several citrus flavonoids. Here again our primary concern was to find evidence, if any, that these compounds are absorbed from the gastrointestinal tract after oral ingestion and, secondly, if absorption does take...

practical and in conformity with the citrus laws and regulations. If you could spend a few months in the Commission office you would be amazed at the number of inquiries received from persons all over the country. Many of these persons request information concerning the citrus industry or its products. One party wants to know something about a new process for extracting citrus juices; another i...

Citrus maxima peel is rich in natural phenolic compounds and has a long use in the traditional medicine. HPLC-DAD analysis on Citrus maxima peel powder exhibited the presence of various phenolic compounds such as caffeic acid and (-)-epicatechin. To determine the plausible hepatoprotective activity of Citrus maxima peel powder, we used carbon tetrachloride (CCl4) treated rat model. Liver damage...

Citrus peels, the waste by-products of citrus juices factories are reckoned valuable healthful functional food. The present investigation performed to assess nutritional status of wheat and fortified biscuits with citrus peels powders. Study included determination of gross chemical composition, caloric value , minerals (Fe, Mn, Cu, Ca, Mg, Na, K and P) of wheat and fortified biscuits with citru...

For diagnosis of citrus bacterial canker by PCR, an internal standard is employed to ensure the quality of the DNA extraction and that proper requisites exist for the amplification reaction. The ratio of PCR products from the internal standard and bacterial target is used to estimate the initial bacterial concentration in citrus tissues with lesions.

Citrus trees harbor a large number of viral and bacterial pathogens. Citrus yellow vein clearing virus (CYVCV), Indian citrus ringspot virus (ICRSV), Citrus yellow mosaic virus (CYMV), Citrus tristeza virus (CTV) and a bacterium, Candidatus Liberibacter asiaticus (CLa) associated with huanglongbing (HLB) disease, the most prevalent pathogens in citrus orchards of different regions in India and ...

Saccharomyces cerevisiae boulardii is frequently used as a dietary supplement to promote intestinal health and reduce the impact of growth of enteric pathogens in livestock, including cattle and swine. Citrus by-products are also fed as dietary supplements that have the additional benefit of inhibiting the growth of enteric pathogens. Previous research identified that supplementation of Sacchar...
