Geographic origin characterization of Brazilian green coffee beans via untargeted metabolomics.

Coffee is a widely popular beverage worldwide, known for its distinct sensory properties which are greatly affected by geographical origin. Herein, we performed an untargeted metabolomic evaluation of green coffee beans (n = 40) from four different regions in Brazil: Cerrado Mineiro, Sul de Minas, Caparaó, and Mogiana Paulista; by using UHPLC-HRMS (ultra-high performance liquid chromatography coupled with high-resolution mass spectrometry). The most significant metabolites responsible for coffee characterization were theobromine, zeatin, phenylacetaldehyde, 2-acetyl-1-pyrroline, chlorogenic acids, ferulic acid, p-coumaric acid, abscisic acid, and jasmonic acid.

Forensic application of sandpaper spray ionization mass spectrometry (SPS-MS): Direct analysis of solid pharmaceutical formulations and edible cannabis products.

In this work, we employed a new ambient ionization mass spectrometry technique, sandpaper spray mass spectrometry (SPS-MS), as an efficient tool to analyze pills and tablets of pharmaceutical formulations. The following samples were analyzed: regulators of blood pressure, cholesterol, and diabetes, and drugs for the treatment of erectile dysfunction (ED). Additionally, a hard candy of Cannabis sativa containing Δ9-tetrahydrocannabinol (Δ-THC) and its related isomer cannabidiol (CBD) was also evaluated.

Investigating the Chemical Profile of Underexplored Parts of (Baru) Using the PS-MS Technique.

The baru ( Vog.), a fruit native to the Cerrado biome, is well-known for its almonds, which are extensively exploited and exported. Unfortunately, the remaining parts of this fruit are often discarded.

Tentative identification of phytochelatins, their derivatives, and Cd-phytochelatin complexes in Ocimum basilicum L. roots by Paper Spray Mass Spectrometry.

An unprecedented and direct PS-MS (paper spray ionization mass spectrometry) method was proposed for the detection of native peptides, that is, glutathiones (GSHs), homoglutathiones (hGSHs), and phytochelatins (PCs), in basil (Ocimum basilicum L.) roots before and after cadmium exposure. The roots were submitted to cold maceration followed by sonication with formic acid as the extractor solvent for sample preparation.

Rapid discrimination of geographical origin of garlic (Allium sativum L.): A metabolomic approach applied to paper spray mass spectrometry data.

Introduction: Distinguishing and categorizing the origin of garlic are highly significant, considering its widespread use as a flavoring agent. With billions of dollars annually in global trade, garlic is frequently susceptible to fraudulent practices.

Methodology: Paper spray ionization mass spectrometry (PS-MS) was employed to quickly analyze garlic samples from distinct geographic origins: China and Brazil.
