introduction: citrus fruits, which belong to the family of rutaceae are one of the main fruit tree crops grown throughout the world. although sweet orange (citrus sinensis) is the major fruit in this group accounting for about 70% of citrus output.citrus fruits are well – appreciated fortheir refreshing juice and health benefits.the health benefits of citrus fruits are linked to the high amount...

In orange-pigmented citrus fruits, the xanthophyll esters are predominant carotenoids, but their biosynthetic origin is currently unknown. this work, seven PYP/XES (Pale Yellow Petal/ Xanthophyll esterase) genes were identified in Citrus genomes, only PYP1-4 and 6 contained structural domains essential for activity. The expression profiles sweet orange other species such as lemon, mandarin pumm...

Orange (C. sinensis) peel flavonoids have antibacterial, antioxidant, anticancer, anti-inflammatory, and antiviral effects. However, there is a scarcity of information in the literature about orange peels flavonoids. So, we estimated phytochemicals hydro-methanolic extract C. sinensis were separated by Column chromatography confirmed with TLC HPLC. After that evaluated antimicrobial, antioxidan...

Gas chromatography with quadrupole time-of-flight mass spectrometry (GC-QTOFMS) and soft ionization generated by a rare-gas plasma is described here for the determination of various chlorophenoxy acid methyl esters and a few chlorinated herbicides. This plasma-based, wavelength-selectable ionization source, which can use Xe, Kr, Ar, Ne, or He as the plasma gas, enables ionization of GC-amenable...

essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on gc-ms analysis, in which limonene had the highest percentage (92.4%). due to various important uses of the compound, a method was developed for isolation and purification of limonene. in this method, for extra purification, a fractional distillation on vigreux column ...

Terpenoid volatiles are isoprene compounds that are emitted by plants to communicate with the environment. In addition to their function in repelling herbivores and attracting carnivorous predators in green tissues, the presumed primary function of terpenoid volatiles released from mature fruits is the attraction of seed-dispersing animals. Mature oranges (Citrus sinensis) primarily accumulate ...
