Interests: analytical and Bioanalytical Chemistry; innovative (micro)extraction procedures; hyphenated instrument configurations; method validation; biological active molecules both synthetic and natural-derived

Dr. Locatelli has been an Assistant Professor at the Department of Pharmacy, University “G. d’Annunzio” of Chieti-Pescara since 2008 where he teaches “Analytical Chemistry and Laboratory of Analytical Chemistry”, and “Clinical Analytical Chemistry”. He held Master's degree in chemistry in 2003, and a Ph.D. in Chemistry Sciences in 2007. He has 12 years of experience in the development and validation of innovative analytical protocols for quantification of drugs, metabolites and natural compounds. The research activity is aimed at the development and validation of chromatographic methods (according to international guidelines, ICH) for the qualitative and quantitative determination of biologically active molecules in human and animal, cosmetics, food, and environmental complex matrices. It provides, in addition, to the study of all processes related to pre-analytical stages such as sampling, extraction and purification, separation, enrichment, even the application of conventional and hyphenated analytical methods for the accurate, sensitive and selective determination of biologically active molecules. These procedures have been applied to different analytes also finding application in clinical and pre-clinical studies designed to assess the pharmacokinetic, bioequivalence and Absorption, Distribution, Metabolism and Excretion (ADME) of the formulations examined, in order to characterize new delivery systems of the active principle to improve their pharmacological properties. In the development of the method, predictive and chemometric models both are applied for the optimization of extraction protocols and for final data processing. Particular attention is given to the new instrument configurations for the quantitative analysis in complex matrix. Scientific activity was attested by more than 83 manuscripts, more than 85 congress communications, 1 patent subject to approval, and 8 book chapters, being also the guest editor for 4 special issues for international peer-reviewed journals, and coeditor of 2 books.

Special Issue Information

Dear Colleagues,

Techniques that can be employed to accelerate extractions, work up, and isolation/purification of the products/metabolites, may be of interest both in the fields of natural products (food, plants, plant-derived products) and in analytical chemistry (biological matrices, clinical trials, sample preparation). In the last few years, the development of innovative procedures has deeply impacted the work of chemists.

The present Special Issue, “Innovative Extraction Techniques and Hyphenated Instrument Configuration for Complex Matrices Analysis”, aims to collect and to disseminate some of the most significant and recent contributions in the interdisciplinary area of innovative extraction procedures from complex matrices followed by validated analytical methods using hyphenated instrument configurations to support the optimization of the whole process and the scale-up possibility.

The scope is broad and includes the use of alternative (green) and/or innovative extraction techniques, optimization of the corresponding parameters by means of experimental design, development of proper solvents (ionic liquids, deep eutectic solvents, cyclodextrins), extract fractioning on the basis of specific biological activities, knowledge of the target structures in order to pursue a targeted analysis, and evaluation of the stability of intermediates/final products.

Accepted paper (both reviews and research papers) could be in the field of: - extraction procedures - hyphenated techniques - food and food supplements analyses - biological analyses - chemometric approaches. Eventually all related to specific biological activities observed.

- Abstract submission     February 2018

- Paper submission     31 May 2018

- Revision (Reviewer)     end of June 2018

- Revised version     end of July 2018

- Final proof     first days of September 2018

Indoor air quality problems are usually revealed by occupants’ complaints. In this study, the odors of two types of hardwood species, namely, Cathy poplar (Populus cathayana Rehd.) and rubberwood (Hevea brasiliensis) were selected and extracted with ethanol-toluene for removal of extractives in an attempt to eliminate the odors. The odorous components of neat and extracted woods were identified by gas chromatography-mass spectrometry/olfactometry (GC-MS/O). The results showed that about 33 kinds of key volatile compounds (peak area above 0.2%) were detected from the GC-MS, and about 40 kinds of odorants were identified from GC-O. The components were concentrated between 15 and 33 min in GC-O, which was different from the concentration time in GC-MS. Lots of the odors identified from GC-O were unpleasant to humans, and variously described as stinky, burnt, leather, bug, herb, etc. These odors may originate from the thermos-oxidation of wood components. After extraction, the amounts and intensities of some odorants decreased, while some remained. However, the extraction process resulted in a benzene residue and led to increased benzene odor.

Branched-chain keto acids (BCKAs) are derivatives from the first step in the metabolism of branched-chain amino acids (BCAAs) and can provide important information on animal health and disease. Here, a simple, reliable and effective method was developed for the determination of three BCKAs (α-ketoisocaproate, α-keto-β-methylvalerate and α-ketoisovalerate) in serum and muscle samples using high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF/MS). The samples were extracted using methanol and separated on a 1.8 μm Eclipse Plus C18 column within 10 min. The mobile phase was 10 mmol L−1 ammonium acetate aqueous solution and acetonitrile. The results showed that recoveries for the three BCKAs ranged from 78.4% to 114.3% with relative standard deviation (RSD) less than 9.7%. The limit of quantitation (LOQ) were 0.06~0.23 μmol L−1 and 0.09~0.27 nmol g−1 for serum and muscle samples, respectively. The proposed method can be applied to the determination of three BCKAs in animal serum and muscle samples. Full article
