In this work we report that volatiles emitted from wounded citrus peel play a major role in host recognition by Penicillium digitatum. Volatiles of various citrus cultivars had a pronounced stimulatory effect on germination and germ tube elongation of green mold pathogen. When exposed to volatiles from grapefruit, the percentage of P. digitatum spores germinated on minimal media was 10-fold hig...

the research focused to evaluate physical, chemical, and sensory properties of raw, blanched, and 2, 4, and 6% osmotically salt treated mandarin (citrus reticulata) peel powder. the yields of mandarin peel powder (mpp) were found in the range of 29.1 to 30.4% (db) for different treatments, which were not significantly different. the bulk density and solubility were found in the range of 1,267-1...

A comparative study between the antioxidant properties of peel (flavedo and albedo) and juice of some commercially grown citrus fruit (Rutaceae), grapefruit (Citrus paradisi), lemon (Citrus limon), lime (Citrusxaurantiifolia) and sweet orange (Citrus sinensis) was performed. Different in vitro assays were applied to the volatile and polar fractions of peels and to crude and polar fraction of ju...

A putative citrus vacuolar processing thiolprotease cDNA (Cit-vac) was isolated from a cDNA library of Citrus fruits (Citrus sinensis L. Osbeck var Washington navel). The cDNA is 58 and 57% identical with vacuolar processing seed proteases from castor bean and soybean, respectively. The Citvac sequence shows a typical signal peptide for entering into the endoplasmic reticulum and two glycosylat...

Abstract Citrus juice processing residues are mainly composed of peel, juice sack and seed. The peel, especially, consists of bioactive compounds such as flavones. Supercritical carbon dioxide (SC-CO2) extraction of flavonoid was carried out at a pressure of 30 MPa and temperature ranging from 80 to 160°C. Ratio of water and ethanol as a co-solvent was varied from 0 to 100%. Flavonoids such as ...

Background: Citrus fruits have some antioxidant and antimicrobial properties. The aim of this study was to determine the chemical compounds, antioxidant, and antimicrobial activities of Essential Oil (EO) of lemon (Citrus limon) peel in vitro and in a food model. Methods: The analysis of the lemon peel EO was carried out using gas chromatography-mass spectrometry. Total phenolic and flavonoid ...

The literature data on the use of agricultural waste, mandarin peel (Citrus reticulata) as a sorption material for removal various pollutants, mainly metal and metalloid ions dyes from aqueous media, are summarized. review, based analysis literary sources, provides information volume waste generation processing citrus fruits, including tangerines. Information is given content chemical compounds...

The present study was designed to evaluate the phytochemical profile and the anti-inflammatory, analgesic and anti-convulsant activity of methanolic extracts of Allium sativum, L.(peel of the bulb), Arachis hypogaea, L. (fruit shell), Citrus limon, L. (rind of the fruit), Punica granatum, L.(rind of the fruit) and Vitis vinifera, L.( seed).

Two new flavanones and one chalcone were isolated from the peel of Citrus kinokuni Hort. ex Tanaka and identified as (2S)-5,6,7,8,4'-pentamethoxyflavanone (1), (2S)-5,6,7,3',4'-pentamethoxyflavanone (2) and 2'-hydroxy-3,4,3',4',6'-pentamethoxychalcone (3). The structures of new compounds were elucidated by spectroscopic analysis.

Comparative antioxidant activities of the water and ethanol extracts obtained from dried citrus fruit (Citrus unshiu) peel were determined using chemical and biochemical in vitro assays. Chemical assays were used for evaluation of 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, hydrogen peroxide scavenging, and reducing power of both extracts and their total phenolic, flavonoid and ta...
