In this work, a chemometric approach to positive electrospray ionization (ESI) optimization for the simultaneous determination of the cyromazine, carbendazim, methomyl, imidacloprid, and thiophanate methyl in vegetable samples by liquid chromatography- mass spectrometry (LC-MS) has been developed.

The objective of this study was to evaluate the biological activities and chemical fingerprint profiles of the extracts obtained from twelve Achillea L. species (A. lycaonica, A. biebersteinii (syn: A. arabica), A. kotschyi subsp. kotschyi, A. schischkinii, A. millefolium subsp. millefolium, A. sintenisii, A. setacea, A. teretifolia, A. wilhelmsii subsp. wilhelmsii (syn: A. santolinoides subsp. wilhelmsii), A. nobilis, A. goniocephala, A. spinulifolia).

The chemical composition, antioxidant properties and antibacterial activities of different extracts (water, ethanol, acetate ethyl and hexane) and essential oil from Platycladus orientalis leaves were analysed in this study. The essential oil was extracted by hydrodistillation, and its chemical composition was determined by gas chromatography coupled to mass spectrometry (GC-MS).

This study aimed to propose a mathematical method to investigate and optimize the simultaneous elimination process of multiple organic pollutants using the Fenton process. Hence, the treatment of rhodamine B (RB) and acid red 14 (AR14) dyes in their binary solution was studied. Multivariate curve resolution alternating least square (MCR-ALS), a novel chemometric method, was applied along with correlation constraints to resolute the UV-Vis spectrophotometric data, enabling quantification of investigated dyes despite a high spectral overlapping.

Today, most investigations of the plant metabolome tend to be based on either nuclear magnetic resonance (NMR) spectroscopy or mass spectrometry (MS), with or without hyphenation with chromatography. Although less sensitive than MS, NMR provides a powerful complementary technique for the identification and quantification of metabolites in plant extracts.

Chemometric Techniques for Quantitative Analysis shows how to produce and use quantitative analytical calibrations in a laboratory or production environment following a variety of methods, how to estimate the time and resources needed to develop analytical calibrations, and how to employ the quantitative software provided with a wide range of instruments and commercial software packages. Among several, this bestselling volume covers basic and classical approaches, component regression; PCR in action; partial least squares; PLS in action.
