Laboratory bioassay of the essential oil extracted from the grapefruit (Citrus paradisi) peel by steam distillation was carried out against the developmental stages of the yellow fever vector Aedes aegypti to evaluate its toxicity, and ovicidal and larvicidal potency. Volatile oil components isolated and characterized by coupled gas chromatography/mass spectrometry included varying levels of mo...

The present study was aimed to evaluate the in vitro thrombolytic, anti-haemolytic and anti-inflammatory activities from essential oil of C. sinensis peel. C. sinensis collected and was subjected to hydrodistillstion by using Clevenger apparatus. The identification of compounds present in the oil of C. sinensis was carried out by gas chromatography and mass spectrometry (GC-MS). In vitro thromb...

The chemical composition, antioxidant and antibacterial activities of essential oil from peel of Citrus unshiu which cultivated in South Korea were investigated. Eight compounds were identified as l-limonene (88.11%), γ-terpinene (4.66%), cyclohexane, 2,4-diisopropenyl-1-methyl-1-vinyl (1.82%), diethyl phthalate (1.02%), β-linalool (0.97%), β-myrcene (0.91%), α-farnesene (0.91%) and o-cymene (0...

Orange peel and pulp were analyzed for their proximate composition, water and oil holding capacity. Data showed that, orange peel and pulp had high amount of dietary fiber (74.87 and 70.64%, respectively) with high proportion of IDF, also it has high level of water and oil holding capacity. Biscuits prepared from blendes containing different proportion (0,5,15 and 25%) orange peel or pulp were ...

Epithelial cells (ECs) lining the secretory cavities of Citrus peel have been hypothesized to be responsible for the synthesis of essential oil, but direct evidence for such a role is currently sparse. We used laser-capture microdissection and pressure catapulting to isolate ECs and parenchyma cells (as controls not synthesizing oil) from the peel of young grapefruit (Citrus × paradisi 'Duncan'...

is added to grapefruit pulp the pulp acts as a bland filler and makes an apple pie. If peach is added it makes a peach pie. Citric acid, sugar and peel oil give excellent orange, grapefruit and tangerine jams. A little' peel oil, sunset yellow, No. 6 and sugar makes a good ice cream mix. Add more sugar and you have a good sundae topping. Cake fillings were made from the jams but they gave troub...

This study evaluated the effect of foliar biostimulants on fruit quality of adult 'Valencia' orange and 'Biancolilla' olive trees. Half of the selected orange and olive trees were sprayed twice before harvest with the SUNRED® commercial mix containing phenylalanine, methionine, mono-saccharides and oxylipins from plant extracts as well as potassium salts and urea. Orange and olive yields and fr...

Tea (Camellia sinensis L.) fruit peel, the main byproduct during the manufacture of tea seed oil, was used as raw material for the recovery of phenolic antioxidants. The effect of ethanol concentration, extraction time, and extraction temperature on total phenolic content (TPC) and ferric-reducing antioxidant power (FRAP) of the extracts from tea fruit peel was investigated. The maximum predict...

In order to qualitative and quantitative study on essential oil, obtained from leaf and peel of Citrus aurantium L. cultivated in North of Iran (Sari city) the leaves and fruits were gathered on April and November 2002, respectivelly. Clevenger apparatus was used for hydro-distillation extraction in order to provide the oil of leaf and peel of Citrus aurantium L. The outputs of each essential o...

Cold pressed peel oil was added to high quality 50°Brix commercial orange concentrate and foam-mat dried, or diluted to single strength juice and freeze-dried using different platen temperatures. Amounts of peel oil ranged from 0.026% to 0.106% for samples to be foam-mat dried, and from 0.011% to 0.109% for freeze drying. For foam-mat drying, previously de veloped standard commercial conditions...
