This research is done to determine the distribution of flavonoids in diverse varieties of onions (commercial and wild onions). Reflux extraction method was done on dried onions and the abstracts were analyzed subsequently by high performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GCMS). Statistical calculations were done to see if there are significant differences in the varieties of onions studied from the chromatographic profiles obtained. The chromatograms obtained were patterned using visual observations, scatter plot study, correlation co-efficient, and ANO

A novel interface for the coupling of high performance liquid chromatography (HPLC) with inductively coupled plasma mass spectrometry (ICP-MS) for the speciation of organometallic compounds has been developed and utilised for a number of diverse applications. Desolvation of the sample prior to reaching the plasma is shown to facilitate a more versatile coupling of the two instrumental techniques. This has been achieved by first volatilising the aerosol after nebulisation of the sample in a heated cyclone spray chamber.

Uracil, a nitrogen base usually found in RNA, may be found in small quantities in genomic DNA. Genomic uracil may arise as a result of deamination of cytosine or misincorporation of deoxyuridine monophosphate (dUMP) instead of deoxythymidine monophosphate (dTMP) by replicative polymerases. Uracil is normally detected as a lesion in DNA and repaired by base excision repair. Failure to do so may lead to genetic mutations. Conversely, the presence of uracil in the genome can be beneficial: it is an important step in the adaptive immunity processes of class switch recombination and somatic hypermu

In recent years, the use of these explosives in improvised explosive devices (IEDs) has increased.

High performance liquid chromatography (HPLC) is the most widely used separation technique within the pharmaceutical industry. Due to the growing need for high speed and high quality separations other techniques, such as supercritical fluid chromatography (SFC), are now being considered. The key advantage of SFC is minimal solvent waste, which is particularly important in preparative SFC, leading to fast sample recovery. Hence it is important to explore whether SFC, which promises to be cheaper and more environmentally friendly than conventional HPLC, can be applied more widely as a complement

Lipids are important for the structural and physiological functions of neuronal cell membranes. Alterations in their lipid composition may result in membrane dysfunction and subsequent neuronal deficits that characterise various disorders. This study focused on profiling lipids of aged and LPS-treated rat brain and liver tissue with a view to explore the effect of atorvastatin in neuroinflammation, and examining lipid changes in different areas of rat brain of the Flinders Sensitive Line (FSL) rats, a genetic model of depression. Lipids and other analytes extracted from tissue samples w

A comprehensive forensic investigation of sensitive ecosystems in the Everglades Area is presented. Assessing the background levels of contamination in these ecosystems represents a vital resource to build up forensic evidence required to enforce future environmental crimes within the studied areas. This investigation presents the development and validation of a fractionation and isolation method for two families of herbicides commonly applied in the vicinity of the study area, including phenoxy acids like 2,4-D, MCPA, and silvex; as well as the most common triazine-based herbicides like atraz

Streszczenie:

A novel analytical method is developed to examine the chemical composition of plant oils by electrospray ionisation high-resolution Fourier transform ion cyclotron resonance mass spectrometry in both positive- and negative-ion modes. To date, this is the first reported application of this technique for the study of macadamia nut oil. Samples of macadamia nut oil from the Macadamia Integrifolia- Proteaceae family (smooth shell) are examined. The fatty acid profile of the oil is obtained by this mass spectrometric examination of the transesterified and hydrolysed oil samples. The Fourier transfo
