Bioactive compounds in 19 chili pepper varieties cultivated in Italy: Suspect screening and in vitro enzyme inhibitory effect.

Chili peppers have been under the spotlight of bioactivity research as they feature a diverse and rich phytochemical profile with multiple health promoting effects. These beneficial properties are related to the chemical composition of chili peppers and is of utmost importance to identify varieties with the strongest bioprospecting potential. In this study, 19 chili pepper varieties were investigated originating from Capsicum annuum L.

as a producer of lipids for antibacterial, antibiofilm and antifungal properties.

The aim of this study was to investigate the antibacterial, antifungal, and anti-biofilm activities of the methanolic extract of marine along with its lipid composition, including carotenoids. The strain, isolated from the Mediterranean coast of northern Morocco, was identified morphologically and molecularly by partial sequencing of the 18S rRNA gene. The methanolic extract of demonstrated significant antibacterial activity against both Gram-positive and Gram-negative pathogenic bacteria, with MIC values ranging from 3.

Determination of main lipids and volatile compounds in unconventional cold-pressed seed oils through chromatographic techniques.

The purpose of this study was to characterize unconventional cold-pressed seed oils (rosehip, strawberry, blackcurrant, carrot, plum, pomegranate, radish, and raspberry) as novel alternative edible oil source. A chemical characterization of different lipid components (total fatty acid composition, triacylglycerols, and vitamin E) and volatiles responsible for the particular aroma of these oils was reported. All the oils showed a content of unsaturated fatty acids, mainly oleic, linoleic, and α-linolenic acid, that potentially contribute to the prevention of cardiovascular diseases, in the range of 80%-90%.

Peach Palm Fruit () Peel: A Source of Provitamin A Carotenoids to Develop Emulsion-Based Delivery Systems.

The peach palm fruit () peel is a byproduct after fruit consumption. The peel flour of two varieties (yellow and red) was separately obtained by hot air drying and was subsequently milled. The proximate analysis showed that the red variety exhibited higher protein, fat, and fiber contents than the yellow one.

Rapid evaporative ionization mass spectrometry: A survey through 15 years of applications.

Rapid evaporative ionization mass spectrometry (REIMS) is a relatively recent MS technique explored in many application fields, demonstrating high versatility in the detection of a wide range of chemicals, from small molecules (phenols, amino acids, di- and tripeptides, organic acids, and sugars) to larger biomolecules, that is, phospholipids and triacylglycerols. Different sampling devices were used depending on the analyzed matrix (liquid or solid), resulting in distinct performances in terms of automation, reproducibility, and sensitivity. The absence of laborious and time-consuming sample preparation procedures and chromatographic separations was highlighted as a major advantage compared to chromatographic methods.

Direct analysis in real time of high-quality extra virgin olive oils for the rapid and automatic identification of origin trademark.

Background: Following our previous research on the differentiation of Italian extra virgin olive oils (EVOOs) by rapid evaporative ionization mass spectrometry coupled to a tandem high resolution mass analyser, the present study deals with the evaluation of another direct mass spectrometry (direct-MS) approach for the rapid and automatic discrimination of EVOOs. In particular, direct analysis in real time (DART-MS) was explored as an ambient MS (AMS) source for the building of a top-quality Italian EVOOs database and fast identification of unknown samples. A single quadrupole detector (QDa) was coupled with DART, taking advantage of a cost-saving, user-friendly and less sophisticated instrumental setup.

Supercritical Fluid Extraction of Oils from Cactus L. and Seeds.

This study aimed to assess the capability of supercritical fluid extraction (SFE) as an alternative and green technique compared to Soxhlet extraction for the production of oils from (OFI) seeds originating from Yemen and Italy and (OD) seeds from Yemen. The following parameters were used for SFE extraction: a pressure of 300 bar, a CO flow rate of 1 L/h, and temperatures of 40 and 60 °C. The chemical composition, including the fatty acids and tocopherols (vitamin E) of the oils, was determined using chromatographic methods.
