Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O) were used to determine the aromatic composition and aroma active compounds of fruit juice and peel oil of Jinchen sweet orange fruit. Totals of 49 and 32 compounds were identified in fruit juice and peel oil, respectively. GC-O was performed to study the aromatic profile of Jinchen fruit juice and peel oil. ...

Varying the strength of the croton oil in a phenol peel solution can customize the peel to suit the needs of each patient and address delicate areas, such as the eyelids and the neck. Here the author presents important refinements in phenol-croton oil peel application.

The volatile secondary metabolites of essential oils from fruit peel and leaves of variegated pink-fleshed lemon (Citrus x limon) were investigated using GLC and GLC-MS (gas-liquid chromatography-mass spectroscopy). Altogether 141 compounds were identified and quantified, accounting for 99.59% and 96.33% of the total hydrodistilled peel and leaf oil, respectively. Limonene occurred in higher am...

Introduction A study was made recently in this laboratory on some possible causes of breakdown in the peel of Washington Navel oranges. One approach to this problem was the determination and evaluation of the relative quantities of volatile oil in the peel of affected and unaffected fruits (2). It was founld early in this investigation that more information was needed than had been published on...

The volatile components of Hallabong ([C. unshiu Marcov x C. sinensis Osbeck] x C. reticulata Blanco) cold-pressed peel oil were quantitatively and qualitatively determined by use of two internal standards with GC, GC-MS, and GC-olfactometry. According to instrumental analysis by GC and GC-MS, limonene (90.68%) was the most abundant compound, followed by sabinene (2.15%), myrcene (1.86%), and g...

The aim of the present investigation was to assess and compare the antimicrobial activities of the lemon (Citrus sinensis) peel extract and lemon oil against common food borne pathogens and to study their potential as food bio-preservatives. The antagonistic activity of lemon peel extract and lemon oil was studied against common food borne pathogens like Staphylococcus aureus, Staphylococcus ep...

conclusions orange peel essential oil did not reduce postpartum depression and anxiety. background mothers are vulnerable to mental disorders, such as depression and anxiety, in the 6-week postpartum period after delivery. objectives this study was performed to determine the potential effect of orange peel essential oil on postpartum depression and anxiety. patients and methods this double-blin...

Citrus oil is a clear volatile oil with a pleasant pungent odor. The material furnished for these experiments was extracted from citrus peel and is double distilled. Citrus peel oil mixed with dehydrated gum turpentine in the proportions of 80 per cent and 20 per cent respectively, has been used commercially as a deodorant and an insect repellant. Because of its penetrating properties citrus oi...

This study reports the optimised conditions (temperature, ethanol concentration and processing-time) for antioxidant extraction from potato peel (Agria variety) waste. At short extraction times (34 min), optimal yields of phenolic (TP) and flavonoid (Fv) compounds were reached at 89.9°C and ethanol concentrations of 71.2% and 38.6%, respectively. The main phenolic compounds identified in the ex...

The aim of this study was to determine the main constituents of the essential oil isolated from Fortunella crassifolia Swingle peel by hydro-distillation, and to test the efficacy of the essential oil on antimicrobial activity. Twenty-five components, representing 92.36% of the total oil, were identified by GC-MS analysis. The essential oil showed potent antimicrobial activity against both Gram...
