“…In literature, various methods are used to detect, measure or separate sugars from plant species. Methods such as High Performance Liquid Chromatography (HPLC) (Inoue, et (Kaijanen, et al, 2015), and Spectrophotometric method (Borji, et al, 2017) are used to measure sucrose, glucose and fructose. In this study, the YSI2500 Biochemistry analyser was used to determine the water-soluble sugars and the HPLC method for structural carbohydrates analysis.…”

Iraq is known with the abundance of date palm trees. This can be an important source of food nutrients and agricultural waste for energy. Date pits represent 18-20% of the fruit weight, and are recognized for their oil content and other nutritional components. This agricultural waste can be of great importance as a source of biofuel or useful nutritional compounds. In this paper, date pits of the most common variety of dates in Iraq named Zahdi, was investigated for compositional analysis and biomass value assessment. Samples of dried pits were examined for sugars, wax & chlorophyll and total inorganic ash content. In addition, structural sugars were examined to assess the potential of producing biofuel from date pits. It is found that the total content of structural sugars was 62.16% mainly Arabinose (53.56%). This highly significant percentage of Arabinose in date pits has not been reported in literature till the present. Further analysis of the volatile organic compounds in the pits via pyrolysis, identified a rare sugar in nature named D-allose. It is believed that thermochemical conversion of polysaccharides has led to produce the monosaccharide d-allose sugar. It is the first time ever to identify this rare sugar in Iraqi date pits with a noticeable amount. The importance of this finding comes from the recent medical investigations that proved the inhibiting activity of D-allose on many carcinoma cells in the human body.

“…After preliminary method development and validation studies (Kaijanen et al , 2015, the CE method was applied to the liquid samples produced from wood-based materials. These samples of hydrolyzed softwood were considered to be case examples and representatives of the primary and secondary streams of processes in forest products industry (Holmbom 2011) either currently utilized or under research to be applied in the future.…”

Monitoring wood-related biorefinery process streams is important as the composition of raw material and its variations have a great impact on the production outcome as well as on the process control. In this paper, the applicability of a simple type of capillary zone electrophoresis method to profiling heterogeneous woodbased samples was studied by grouping the peaks in the overall electropherograms. A comparison between 210 and 270 nm as an example confirmed the identification of a monosaccharide peak in the carbohydrate electropherogram. The analytical method applied in this study was found suitable, firstly, in profiling the samples based on correlation of multiple detection wavelengths and, secondly, in characterizing the total carbohydrate composition by grouping detected peaks by the compound type. Compounds were detected in their extracted form without timeconsuming pretreatment procedures. Differences in the raw material and process conditions were successfully identified by comparing characteristic peaks in the sample electropherograms of an example case.
