background and objectives: the chemical composition and antimicrobial activity of bitter orange (citrus aurantium) leaf, ripe and unripe peel essential oils, cultivated in southwest of iran, were investigated. materials and methods: the analysis of chemical composition of hydro-distilled essential oils was carried out by gc-ms. the disc diffusion and broth micro-dilution were used to assay the ...

BACKGROUND The current treatments for anxiety disorders and depression have multiple adverse effects in addition to a delayed onset of action, which has prompted efforts to find new substances with potential activity in these disorders. Citrus aurantium was chosen based on ethnopharmacological data because traditional medicine refers to the Citrus genus as useful in diminishing the symptoms of ...

The polyamines (PA) putrescine (Put), spermidine (Spd), and spermine (Spm) were measured during 3 weeks exposure to cold hardening (15.6 degrees C day and 4.4 degrees C night) and nonhardening (32.2 degrees C day and 21.1 degrees C night) temperature regimes in three citrus cultivars: sour orange (SO) (Citrus aurantium L.), ;valencia' (VAL) (Citrus sinensis L. Osbeck), and rough lemon (RL) (Cit...

Oxidative stress and apoptosis contribute to neuronal degeneration in many neurodegenerative diseases such as Alzheimer's disease. Glutamate is a major excitatory neurotransmitter in the central nervous system (CNS) and is considered responsible for the pathogenesis of many neurological disorders. Reactive oxygen species (ROS) production is thought to be involved in glutamate-induced apoptosis ...

Flavanones constitute the majority of flavonoids in citrus fruits such as sweet (Citrus sinensis) and sour oranges (C. aurantium) and their near relatives—tangerines/mandarins (C. reticulata), tangors and tangelos. The relevant chemical analytic literature was searched, abstracted, documented, standardized, examined for quality, enumerated, and summarized in a database for these citrus flavanon...

Flowering is a critical step in fructification. No flowers mean no fruit, and when flower number is low crop load may be limited by the number of flowers formed. In most cases, however, citrus trees form a number of flowers exceedingly higher than the final number of fruits harvested, which usually is a very low percentage of the initial flower number. As in other species which form a large amo...

The isoelectric points of isolated cuticles from Citrus aurantium L. (3.15), Prunus armeniaca L. (3.45), and Pyrus communis L. (2.90) leaves were determined from membrane potentials. At pH values below the isoelectric point, cuticular membranes carry a net positive charge and are permselective to anions (determined using (82)Br(-)). Above the isoelectric point, they carry a net negative charge ...

To examine the safety and efficacy of citrus aurantium, an herb now commonly used as a substitute for ephedra in dietary supplements marketed to promote weight loss, we conducted a systematic review. An extensive search of MEDLINE, EMBASE, BIOSIS, and the Cochrane Collaboration Database identified only 1 eligible randomized placebo controlled trial, which followed 20 patients for 6 weeks, demon...
