Bioactive effects of citrus flavonoids and role in the prevention of atherosclerosis and cancer
2022
Citrus fruits are the main fruits of the Mediterranean diet and have been long recognized for their beneficial effects on human health. Observational studies have shown a significant association between dietary flavonoid intake and reduced risk of cardiovascular and malignant diseases. The beneficial effects of citrus fruits on human health appear to be due to their high content in vitamins, minerals and fibers. In particular, the antioxidant and anti-inflammatory activities have been indicated as some of the mechanisms through which citrus fruits may thwart the development of chronic degenerative diseases such as atherosclerosis and cancer. This review would critically examine the results …

The ancient urban agroforestry systems of the Conca D'Oro (Palermo, Italy) need protection to defend the city
2019
The favorable environmental conditions together with the ancient agronomic practices, e.g. the irrigation systems introduced by the Arabs, have made the plain surrounding Palermo, known as Conca d’Oro, the unique agriculture landscape famous worldwide. Several tree and vegetable species have spread throughout in time but the new crops, instead of replacing the others, were often integrated exploiting the different heights of the tree canopies. The result was the creation of complex agroecosystems characterized by orchards with several layers of trees (as walnut, loquat, citrus) and empty spaces where the farmers cultivated vegetables. The grass fed the animals in the stables while manure wa…
Citrus somatic hybrid leaf essential oil
2000
The essential oil from the leaves of a Citrus interspecific somatic hybrid obtained by symmetric protoplast fusion between ‘Milam’ lemon [purported sexual hybrid of C. Jambhiri Lush (×) C. sinensis] and ‘Femminello’ lemon (C. limon L. Burm f.) has been characterized by steam distillation GC–MS analysis and its composition compared with that of the corresponding oils obtained from the parent plants. The amount (%) of the different classes of substances present in the oils show, in the new hybrid, an overall lowering of the hydrocarbon fraction and an increase of the oxygenated components. The somatic hybrid shows a close similarity in the amounts of terpenes, sesquiterpenes and alcohols with…
Morphogenic responsein vitroof epicotyl segments ofCitrus macrophylla
2008
Abstract The influence of explant orientation, contact of the cut surface with the medium, type of growth regulators and distance of epicotyl cuttings from the cotyledonary node (the part of the seedling where the cotyledons are attached) on in vitro morphogenesis of Citrus macrophylla (alemow) was evaluated. Maximum number of shoots was induced from epicotyl segments placed horizontally.
Survey of Citrus tristeza virus in Southern Italy
2010
After a recent detection of Citrus tristeza virus (CTV) in Calabria (Southern Italy), an investigation was initiated in the spring 2006 to survey for the virus in this Region. The survey showed that CTV was not present in the nurseries which indicated that citrus mother plants and citrus plantlets ready for marketing have fulfilled completely the phytosanitary requirements. CTV was not detected in citrus-growing areas of Catanzaro, Cosenza and Crotone Provinces, but was found, at different levels in infected plants, in some orchards located in the Reggio Calabria and Vibo Valentia Provinces. Since the virus was detected not only in material illegally imported from abroad but also in local v…
Free and conjugated polyamine content in Citrus sinensis Osbeck, cultivar Brasiliano N.L.92, a Navel orange, at different maturation stages
2004
Biogenic amines, synthesized during physiological metabolic processes of all living organisms, are present in food. At low concentrations, polyamines are essential for cell renewal and growth, but they can be detrimental when consumed in high amount through the diet as they could support abnormal cell growth pathologies. The daily human diet contains more putrescine than spermidine or spermine, mostly derived from fruits. In general, orange fruits contain high levels of put, a fact that could limit their utilization in the daily diet besides the benefits contributed by their strong antioxidant properties. There is therefore an increasing interest in finding plant foods with low polyamine co…
Effect of polyamines on in vitro anther culture of Citrus clementina Hort. ex Tan
2006
The improvement of the induction rate in Citrus anther culture is important for taking practical advantage of the haploid potential in breeding. The influence of polyamines on anther culture of Citrus clementina, cv Nules, with particular attention to the free, soluble and insoluble-conjugated polyamine levels, has been investigated. Putrescine, spermidine and putrescine plus spermidine, were added to the standard induction medium. Before culture, spermidine was the most abundant among the free polyamines detected in anthers. The exogenous supply of either putrescine or spermidine, either independently or combined, effected greater uptake and accumulation of polyamines. The addition of 2 mM…
An Integrated Approach to Mandarin Processing: Food Safety and Nutritional Quality, Consumer Preference, and Nutrient Bioaccessibility
2017
Mandarins are a member of the Citrus genus and are the focus of growing commercial interest, with satsuma mandarins (Citrus unshiu) and the common mandarin (Citrus reticulata Blanco) being the most important mandarin varieties. The possible health benefits and functional properties of those fruits are often associated with the antioxidative function of vitamin C, carotenoids, and phenolic compounds. While most mandarins are consumed fresh, many are processed into juices (mostly cloudy), usually via thermal processing which can lead to the creation of off-flavors and may diminish nutritional quality. The aim of this review is to summarize the most significant and recent information on the sa…
Le lumie di Sicilia: note storiche e botaniche
2015
Citrus lumia Risso is one of the old cultivated limes in Sicily, Mediterranean Europe and North Africa; For this reason, besides lumia, it is called Mediterranean lime. It is a small tree, with unarmed branches; obovate, obtuse leaves, with serrate margins and slightly winged petioles; flowers of medium size, fragrant, with petals externally reddish; fruit globose, umbonate, with base and apex de- pressed; umbo conical, dotted at the base; smooth, yellow-sulphureous, aromatic peel; thin and bitter mesocarp; endocarp with sweet juice, consisting of 9 -11 logs containing many seeds. It is distinguished from C. limetta Risso by the colour of petals and some other carpological and foliar charac…
