To assess the extraction methods of egg yolk oil in ShiZhenKang (SZK) oil, which is used to treat eczema, a mice model of eczema was established by using 2,4-dinitrochlorobenzene (DNCB). The therapeutic effects of egg yolk oil extracted by different methods from SZK oil on the model of acute eczema in mice were evaluated. The oil yield rate of ethanol extraction is 42.06%. Its egg yolk oil is o...

ABSTRACT: Due to the importance of essential oils and their use in various industries, the essential oils of four types of citrus consisting of orange (C. sinesis), tangerine (C. reticulate), sweet lemon (C. limetta) and sour lemon (C. limon) were extracted and subjected to chemical analysis to identify and evaluate the chemical constituents of the oils. The average essential oils of orange, ta...

Materials and methods: One hundred eighty 21-day-old Yorkshire-Landrace pigs were randomly assigned to five treatments. Treatments were the unsupplemented, unmedicated basal diet (Control) and the basal diet supplemented with either 4.41 g per tonne flavomycin (Huvepharma, Inc, Peachtree City, Georgia; Flavomycin), 1.5 kg per tonne oregano oil (Van Beek Scientific, Orange City, Iowa; Oregano), ...

The possibility of stabilizing emulsions of water and non-polar alkane with pure, coloured organic pigment particles is explored. Seven pigment types each possessing a primary colour of the rainbow were selected. Their solubility in water or heptane was determined using a spectrophotometric method and their surface energies were derived from the contact angles of probe liquids on compressed dis...

Essential oil was extracted from peels of sweet orange fruits by supercritical technique and the resulting compounds were analyzed by gas chromatography. After emulsifying with tween-20 in sterile water, the antibacterial efficacy against Vibrio parahaemolyticus, Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus, which were inoculated on the surfaces of samples of stainless st...

The results of gas chromatography/mass spectrometry (MS), with Ion Signature Technology, Inc. (North Smithfield, RI) quantitative deconvolution software, are discussed for pesticides identified both as target compounds by using retention and MS data and as unknowns by using only mass spectra. Target compound analysis of 32 pesticides, surrogates, and an internal standard added to lemon oil over...

Recently, there has been a great deal of attention on usage, byproducts, and wastes of the food industry. There have been many studies on the properties of citrus seeds and extracted oil from citrus grown in Kerman, Iran. The rate of oil content of citrus seeds varies between 33.4% and 41.9%. Linoleic acid (33.2% to 36.3%) is the key fatty acid found in citrus seeds oil and oleic (24.8% to 29.3...

The increasing popularity of essential oils for skincare has led to investigation of their biological effects in human skin cells. In this study, we investigated the biological activities of three commercially available essential oils, i.e. rosemary oil, wild orange oil, and a blend (commercial name: Deep Blue) composed of oils from wintergreen, camphor, peppermint, blue tansy, German chamomile...
