This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

The large RNA genome of Citrus tristeza virus (CTV; ca. 20 kb) contains 12 open reading frames, with the 3'-terminal one corresponding to a protein of 209 amino acids (p23) that is expressed from an abundant subgenomic RNA. p23, an RNA-binding protein with a putative zinc-finger domain and some basic motifs, is unique to CTV because no homologs have been found in other closteroviruses, includin...

Citrus tristeza virus (CTV) (genus Closterovirus, family Closteroviridae) causes some of the more important viral diseases of citrus worldwide. The ability to map disease-inducing determinants of CTV is needed to develop better diagnostic and disease control procedures. A distinctive phenotype of some isolates of CTV is the ability to induce seedling yellows (SY) in sour orange, lemon and grape...

Three-year-old citrus trees were grown in the greenhouse to study the effects of fertilizer concentration and root herbivory on plant growth and mineral concentration. In separate experiments, sour orange (Citrus aurantium L.) and Swingle citrumelo (C. paradisi Macf. Poncirus trifoliate L.) plants were treated with a complete fertilizer diluted to provide 25, 100, 200, or 400 ppm N and grown fo...

pruritis is a common dermatic condition which can be the symptom of many localized and systemic infections,for which these is no specific treatment.most of the drugs used only lessen the symptoms,and they all have side effects.based on this,and since in Iranian traditional medicine sour orange fruit has been implicated as having antipruritic effects,in this study the latter effect was studied.a...

Introduction: Based on the documents in traditional medicine regarding the therapeutic effect of Sour orange flowers (Citrus aurantium L.) on the nervous system disorders, this experimental study was conducted to evaluate the pretreatment of Sour orange flowers extract in preventing or reducing depressive-like behaviors induced by systemic injection of lipopolysaccharide (LPS) in rats. Method: ...

abstract: due to the importance of essential oils and their use in various industries, the essential oils of four types of citrus consisting of orange (c. sinesis), tangerine (c. reticulate), sweet lemon (c. limetta) and sour lemon (c. limon) were extracted and subjected to chemical analysis to identify and evaluate the chemical constituents of the oils. the average essential oils of orange, ta...
