| Abstract Erodium glaucophyllum collected from Tunisian Sahara was never presented in the relevant literature yet. In this study, the phytochemical profiles, chemical compositions, antioxidant and antimicrobial activities, and Kill-time assay of the hydroalcoholic extract of flowers and leaves were investigated. The highest content in phenols, flavonoids and tannins was shown in flowers extract (350 ± 5 mg GAE/g, 34 ± 1 mg QE/g and 221.8 ± 0.0 mg β-carotene E/g, respectively). The carotenoids amount in leaves was about 6-fold higher than it’s in flowers. Conducted LC/MS analysis revealed the presence of 17 compounds in flowers and leaves extract with the main were quinic acid and naringin followed by rutin, hyperoside, gallic acid and... |

| In the context of the French Phytoplankton and Phycotoxins Monitoring Network (REPHY) programme, shellfish samples were harvested from different locations where harmful algae blooms were known to have occurred. For all shellfish samples found positive by the mouse bioassay for diarrhetic shellfish poisoning (DSP) toxins, liquid chromatography (LC) coupled with mass spectrometry (MS) was used to search for the following lipophilic toxins: okadaic acid (OA), dinophysistoxins (DTXs), pectenotoxins (PTXs), azaspiracids (AZAs), yessotoxins (YTXs), spirolides (SPXs) and gymnodimines (GYMs). In order to investigate the presence of acyl-OAs and/or acyl-DTX-1,-2 (DTX-3), alkaline hydrolysis was performed on all samples, and LC/ MS analyses were carried out on the... |
