Abstract:
The aim of this study was to analyze the urea content of Dairy Cattle Feed (DCF) using High Performance Liquid Chromatography via Refractive Index Detector (HPLC-RID), without derivatization, along with spectro-colorimetric method that is the official control method of European Union (EU). Towards that goal, the analysis procedure for the method was established, method optimization and validation were carried out by spiking urea at 2% level to DCF, which is the upper limit allowed for use in ruminant feeds in Türkiye. In method validation; R2: 0.9997 coefficient of determination at 25-100000 mg/kg linear range, 75 mg/kg limit of detection (LOD) and 250 mg/kg limit of quantification (LOQ), 1.08% repeatability RSD, 1.84% reproducibility RSD and 95.10% recovery were obtained. The applicability of the method was proven at 25-100000 mg/kg linear range with real samples by spiking 2% urea in Urea-Free Dairy Cattle Feed (UF-DCF), Low Urea Dairy Cattle Feed (LU-DCF), and High Urea Dairy Cattle Feed (HU-DCF). The presence of urea in UF-DCF was detected with the spectro-colorimetric (at 420 and 435 nm wavelength) method, while urea in UF-DCF was not detected by the in-house HPLC-RID method, (P<0.05). The amount of urea in LU-DCF without spiking urea was detected by the same level as HPLC-RID method and the SC-435 method (P>0.05). For HU-DCF blank samples, higher urea amounts were detected with the in-house HPLC-RID method as compared to the spectro-colorimetric methods used in the study (P<0.05). In DCF spiked with 2.0% urea, the urea amount found in the in-house HPLC-RID method were higher than that of the spectro-colorimetric method (P<0.05). As a result, the in-house HPLC-RID method that is developed in this study has shown great promise to be a potential, applicable and valid method for determining the urea amount in DCF.

Abstract:
Five HPLC methods were employed for the quantitative analysis of three natural sugars namely fructose, glucose and sucrose in soft drinks. HPLC-refractive index detector (RID)-AMINO proved to be the most suitable HPLC method to carry out the latter task. For the optimum separation and response of the natural sugars the best conditions employed were column oven temperature 30 oC, flow rate 0.1 mL/min, mobile phase ratio acetonitrile:water 75:25 and they were determined by studying all possible interactions among these three parameters. Full validation of HPLC-RID-AMINO was performed in terms of system suitability test, precision check, accuracy check and robustness.

Abstract:
The quantitation of sugars, including glucose, the primary fermentable sugar; maltose (DP2); and maltotriose (DP3), is a standard procedure during the corn-to-ethanol fermentation process. The quantitation of glucose by the Megazyme Assay utilizing glucose oxidase and peroxidase enzymes (GOPOD) and UV-Vis detection, high-performance liquid chromatography with refractive index detection (HPLC-RID), and liquid chromatography mass spectrometry (LC-MS) with electrospray ionization (ESI) and selected ion monitoring (SIM) was studied. Three biological flask fermentation replicates were analyzed every 12 h beginning at 14 h of fermentation (T14) until near completion of fermentation (T62). The method comparison results for glucose quantitation showed that the LC-MS SIM analysis had the lowest limit of quantitation (LOQ) at 2 ppm and the widest dynamic range of 2.7 orders of magnitude. The HPLC-RID analysis had a linear dynamic range (LDR) of 1.5 orders of magnitude with an LOQ of 1500 ppm. The Megazyme GOPOD analysis had an LDR of 0.9 orders of magnitude with an LOQ of 120 ppm. The HPLC-RID method was ideal for glucose quantitation when it was present in high concentrations. In contrast, maltose and maltotriose components were found to be present in lower concentrations, such that simultaneous quantitation of the three analytes is difficult during fermentation. The LC-MS method was the only method able to quantify the concentration of glucose successfully and simultaneously with DP2 and DP3 in all the fermentation broth samples collected from T14 through T62 during the corn-to-ethanol fermentation process.

Abstract:
Heat treatment is applied to dairy products to ensure microbiological quality and increase the shelf life. However, a suitable control of this process is necessary to guarantee nutritional and sensory quality. The aim of this study is to adapt the high performance liquid chromatography (HPLC) method for determination of lactulose and lactose content in commercial samples of UHT and sweetened condensed milk. The HPLC method used showed a good resolution of the analytes evaluated. The analyzed UHT milk samples presented levels for lactulose in accordance with the limit recommended by the International Dairy Federation. There was no significant variation in lactulose concentration for sweetened condensed milk samples. However, one sweetened condensed milk sample showed lactose level lower than the established values (10–12%).

Abstract:
Red ginseng (RG) has been extensively utilized in Asian countries due to its pharmacological effects. For the quality evaluation of RG, small molecules, such as ginsenosides, have been widely considered as candidates of its quality markers (Q-markers), and various analytical techniques have been developed in order to identify these compounds. However, despite the efforts to analyze the hydrophobic constituents, it is worth pointing out that about 60% of the mass of RG is made of carbohydrates, including mono-, oligo- and polysaccharides. Consequently, the quality differentiation and identification of RG from the perspective of sugar-markers should be focused. High performance liquid chromatography and evaporative light scattering detector (HPLC–ELSD) method for the determination of disaccharides in RG was established. Furthermore, high performance size exclusion chromatography–multi-angle laser light scattering–refractive index detector (HPSEC–MALLS–RID) for the determination of molecular weight and high performance liquid chromatography photodiode array (HPLC–PDA) for the determination of compositional monosaccharides in RG polysaccharides were also established. HPLC–ELSD/PDA combined with HPSEC–MALLS–RID could be used to determine the contents of disaccharides, molecular weights, and compositional monosaccharides of RG polysaccharides, which could be used for quality control, and this is a new view on the sugar marker to quality differentiation of various origins of RG.

Abstract:
Objective: The aim of the current study was to evaluate the black salsify (Scorzonera hispanica L.) as a potential source of inulin and to characterize the physicochemical properties of isolated polysaccharide.Methods: The carbohydrate content in its roots and leaves was analyzed by high-performance liquid chromatography with refractive index detection (HPLC-RID) method. Microwave-assisted extraction was performed for isolation of inulin from black salsify roots. The obtained polysaccharide was characterized by HPLC-RID method, HPLC size-exclusion chromatography, and Fourier transformed-infrared spectroscopy. Functional properties as swelling capacity, solubility, and water-holding and oil-holding capacities (OHCs) were also evaluated.Results: Black salsify (S. hispanica L.) roots were evaluated as a rich source of inulin (22% dw) and 1-kestose (6.25 g/100 g dw). The isolated inulin (yield 20%) was characterized with average degree of polymerization 17, with polydispersity index (1.04) that was near to medium-chained inulin. This polysaccharide showed better OHC than water-holding capacity, and it was characterized with swelling capacity 0.5 ml/g sample.Conclusion: For the first time, inulin was isolated from black salsify roots. The chemical characterization of inulin reveals the potential of this plant to be used as a valuable source of this polysaccharide for future application in food technology and pharmaceutical industry for dietary fibers, stabilizer, and coating agent.

Abstract:
Carbohydrate analysis can be used as a standard analysis for quality control of industries of plants, foods and pharmaceuticals. Quantitative 1H NMR spectroscopy (qNMR) is an excellent alternative to chromatography-based mixture analysis. However, the application of qNMR in sugar analysis has rarely been reported. In this study, the performance of qNMR in sugar analysis was investigated and compared with the results from HPLC analysis. A head-to-head comparison of qNMR (internal and external standard methods) versus HPLC (PMP pre-column derivatization HPLC, HPLC-RID and HPLC-ELSD) based on quantitative analysis of four carbohydrates (fructose, glucose, sucrose and maltose) in Yiqi Fumai lyophilized injection (YQFM) is presented. Both assays showed similar performance characteristics, including linearity range, accuracy, precision and recovery, and analysis times of less than 30 min/sample. After methodological validation, both qNMR and HPLC have good accuracy, precision and stability. Indeed, the qNMR method is simple, sensitive and rapid in quantifying the four sugars. By analysis of variance (ANOVA) for sugar content with HPLC and qNMR methods, we demonstrated that the two analytical methods had no significant difference and could be used interchangeably for the quantitative analysis of carbohydrates.

Abstract:
This paper provides a review of the pharmacopoeial methods for determination of the content of glucose in parenteral solutions (HPLC/RID method, polarimetry and volumetric titration) and evaluation of all critical aspects of the proposed methods, with a focus on accuracy, precision, time of analysis and resources for introducing, maintenance and conducting analysis. Comparative analysis of the results from assay (ten independent determinations) of Glucose 5% w/v solution for intravenous infusion, obtained using all three methods, was performed. The analysis confirmed that there is no statistical difference between the testing results obtained with each method, indicating that all three methods provide valid accurate and precise results. However, the availability of the equipment and trained personnel may be the crucial factor for small laboratories for selection of the method for assay of glucose in parenteral preparations. The obtained results and discussion on all critical aspects (accuracy, precision, time of analysis and resources for introducing, maintenance and conducting analysis) of the proposed methods, provide a valuable input to small laboratories on the suitability of these methods for quality control of Glucose 5% w/v solution for intravenous infusion.

Abstract:
Detection in High Performance Liquid Chromatography (HPLC) is most often done by optical methods1. The most popular detection modes, in order of importance are, absorption, fluorescence, refractive index (RID) or optical activity (OAD). It is known2 that the measured changes in those physical properties are always associated with changes in refractive index (Δn) in the mobile phase. This coupling of refractive index (RI) usually shows up in the response of detectors as non-linearity2, increased noise level or, even spurious response, which all have detrimental effects on the quantitative evaluation of chromatograms.
