A sensitive HPLC-FLD method combined with multivariate analysis for the determination of amino acids in l-citrulline rich vegetables
Publication date: Available online 23 April 2019Source: Journal of Food and Drug AnalysisAuthor(s): Karen A. Corleto, Jashbir Singh, G.K. Jayaprakasha, Bhimanagouda S. PatilAbstractThe proposed analytical method reports the separation and quantification of 21 amino acids including l-citrulline from fresh vegetables and commercial juices using C8 column. Optimal separation conditions for amino acids analysis were obtained with 20 mM sodium acetate (solvent A) and water with organic modifier acetonitrile and methanol (solvent B; 18/50/32 V/V). The ideal pH and column temperature were found to be 5.40 and 35 °C, respectiv...

Detection of BPDE-DNA adducts in human umbilical cord blood by LC-MS/MS analysis
In this study, we employed our developed LC-MS/MS method to detect and quantity BPDE-dG adducts present in 42 normal human umbilical blood samples and 42 birth defect cases. We determined that there is no significant difference in the level of BPDE-dG formation between the normal and birth defect groups. This represents the first time to use an LC-MS/MS method to quantify BPDE-dG in human umbilical blood samples. The results indicated that under experimental conditions, BPDE-dG adducts were detected in all the human umbilical blood samples from the normal and birth defect groups.Graphical abstract (Source: Journal of Food and Drug Analysis)

Determination of phenylenediamines in hair colors derivatizated with 5-(4, 6-dichlorotriazinyl)aminofluorescein via micellar electrokinetic chromatography
Publication date: Available online 21 March 2019Source: Journal of Food and Drug AnalysisAuthor(s): Hung-Yu Ko, Yi-Hui Lin, Chi-Jen Shih, Yen-Ling ChenAbstractPhenylenediamines (PDs), which are reported to cause allergic dermatitis and possess genotoxicity and carcinogenicity, are the ingredients used in permanent hair dyes. The fluorescent derivatization strategy coupled with micellar electrokinetic chromatography (MEKC) were established to analyze four PDs, including o-phenylenediamine (OPD), m-phenylenediamine (MPD), p-phenylenediamine (PPD) and toluene-2,5-diamine (PTD). Additionally, 5-(4, 6-dichlorotriazinyl) aminofl...

Comparative quality of the forms of decoction pieces evaluated by multidimensional chemical analysis and chemometrics: Poria cocos, a pilot study
Publication date: Available online 21 March 2019Source: Journal of Food and Drug AnalysisAuthor(s): Li-Xia Zhu, Jun Xu, Yun Wu, Li-Fei Su, Kelly Yin Ching Lam, Elizabeth R. Qi, Xiao-Ping Dong, Hu-Biao Chen, Yu-De Liu, Zhong-Zhen ZhaoAbstractMany Chinese medicinal materials (CMMs) are parts of plants or fungi that have been processed into different physical forms, termed decoction pieces, that are typically boiled in water for consumption. One CMM may have several decoction pieces forms, e.g., slices, small cubes (dice), or grains. The specifications that have different morphological parameters (shape, size and thickness) f...

Multi-residue analysis using liquid chromatography tandem mass spectrometry for detection of 20 coccidiostats in poultry, livestock, and aquatic tissues
In this study, we developed a novel analysis method based on liquid chromatography/tandem mass spectrometry (LC–MS/MS) to allow the simultaneous identification of 20 coccidiostats in eight matrix categories, including the muscles of chicken, swine, cow, and fish as well as chicken eggs, bovine milk, and porcine viscera. In the pretreatment procedure, acetonitrile/methanol (95:5, v/v) containing 1% formic acid, 5 g of sodium acetate, and 6.0 g of anhydrous magnesium sulfate was used for extraction, followed by a clean-up procedure using n-hexane saturated with ACN to facilitate the elimination of analytes from high lipi...

Potential prebiotics and their transmission mechanisms: Recent approaches
Publication date: Available online 4 March 2019Source: Journal of Food and Drug AnalysisAuthor(s): Ishu Khangwal, Pratyoosh ShuklaAbstractPrebiotics are non digestible carbohydrates which can be used as prime source of energy for gut microflora. These can be naturally occurring in fruit and vegetables or can be made synthetically by enzymatic digestions. New versatile sources of prebiotics had been found nowadays for economic commercialization. This review will decipher on highlighting the importance of prebiotics in immunomodulation and nutrient absorption abilities of gut, as it is important for anti-effective capacity o...
