Previous research showed that exposure to the aroma of orange oil (Citrus sinensis L.) increased the mating success of male Mediterranean fruit flies (medfly), Ceratitis capitata (Wiedemann). This work, however, involved the exposure of small groups of males (n = 25) in small containers (volume 400 ml). In implementing the Sterile Insect Technique (SIT), several programs use plastic adult reari...

OBJECTIVES The aim of this study was to evaluate the volume of remaining filling material after passive ultrasonic irrigation (PUI) of sodium hypochlorite (NaOCl) and orange oil in mesial canals of mandibular molars, with and without isthmus. MATERIAL AND METHODS Thirty mesial roots of mandibular molars were divided according to the presence or absence of isthmus. Canals were prepared and fil...

The present work investigates the effect of ripening stage on the chemical composition of essential oil extracted from peel of four citrus: bitter orange (Citrus aurantium), lemon (Citrus limon), orange maltaise (Citrus sinensis), and mandarin (Citrus reticulate) and on their antibacterial activity. Essential oils yields varied during ripening from 0.46 to 2.70%, where mandarin was found to be ...

Absorbance spectra of cone outer segments and oil droplets were recorded microspectrophotometrically in the retina of the red-eared turtle, Trachemys scripta elegans. There are four cone visual pigments, with lambda(max) = 617 nm (red sensitive), 515 nm (green sensitive), 458 nm (blue sensitive), and 372 nm (UV-sensitive). The red-sensitive pigment resides in single cones with red or orange oil...

introduction: the purpose of this in vitro study was to evaluate three common gutta-percha solvents’ effectiveness in dissolving three different types of root canal sealers. materials and methods: the solubility of three different root canal sealers (ah plus, apexit plus and endoflas fs) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). one-hundred t...

Background: Orange peel essential oils were obtained using supercritical fluid extraction. This method is an important high scaling extraction methods that used for extraction of plant and animal extracts. Methodology: The experimental parameters of SFE such as temperature, pressure, and extraction time and modifier volume were optimized using a central composite design after a 24-1fractional ...

The peel components of Mandarin, Sour lemon and Sour orange were analyzed. Peel flavorcomponents were extracted using cold-press method and eluted using n-hexane. All compoundswere analyzed using GC-FID and GC-MS. Twenty-seven, Twenty-four and Twenty-nine peelcomponents were identified in Mandarin, Sour lemon and Sour orange respectively. They includealdehydes, alcohols, esters, monoterpenes an...

dicated that the developed flavor descriptive analysis procedure can be used either in Spain or USA with similar outcomes. Orange juices prepared using similar processes in both countries had comparable flavor characteristics. Thus, hand-squeezed orange juices were described with citrus fruits, green and floral attributes. Pasteurized products were also described as citrusy, green and sweet fru...

The antimicrobial properties of essential oils, terpineol, and orange oil, in particular, varied according to the type of bacteria tested. Terpineol and other terpeneless fractions of citrus oils appeared to have greater inhibitory effect on food-borne bacteria than the other citrus oils or derivatives. Gram-positive bacteria were, in general, more sensitive to essential oils than gram-negative...
