Unlabelled: BACKGROUND PISUM SATIVUM: (PS) is a universal legume plant utilized for both human and animal consumption, particularly its seeds, known as green peas. The processing of PS in food industries and households produces a significant amount of waste that needs to be valorized.

Methods: In this study, the metabolite profiles of the 70% ethanolic extracts of PS wastes, namely peels (PSP) and a combination of leaves and stems (PSLS), were investigated by liquid chromatography-electrospray ionization-quadrupole time-of-flight tandem mass spectrometry (LC-ESI-QTOF-MS/MS) followed by molecular networking.

Article Synopsis
  • - Carob seeds (Ceratonia siliqua L.) are primarily known for their edible pulp, but their seeds are also a key source of the food additive E410 and contain various beneficial metabolites.
  • - The study successfully isolated two flavonoid compounds from the seeds—quercetin-3-O-rhamnoside and 4'-p-hydroxybenzoylisorhamnetin-3,7-di-O-rhamnoside—using methanol extraction and advanced analytical techniques like HPLC and LC-MS.
  • - These isolated compounds displayed significant cytotoxic effects against renal and colorectal cancer cell lines, with 4'-p-hydroxybenzoylisorhamnetin-3,7-di-O-r

Introduction: This research explores sustainable applications for waste generated from fenugreek (Trigonella foenum-graecum), a plant with both nutritional and medicinal uses. The study specifically targets waste components as potential sources of nutrients and bioactive compounds.

Objectives: The focus is to conduct detailed metabolic profiling of fenugreek waste, assess its anti-inflammatory properties by studying its cyclooxygenase (COX) inhibitory effect, and correlate this effect to the metabolite fingerprint.

Hyperlipidaemia, characterised by elevated levels of lipids, particularly LDL-C, is a significant risk factor for atherosclerotic cardiovascular disease. While synthetic inhibitors of microsomal triglyceride transfer protein (MTP) have shown potential in lowering LDL-C, they are associated with adverse effects. This study explores a novel approach by screening natural products to identify plant extracts that down-regulate MTP gene expression, aiming to reduce hyperlipidaemia with fewer side effects.

, , and were acquired from the Egyptian market, profiled for their chemical constituents, screened for the MAO-B inhibitory activity and evaluated for the total phenolic content. Thirty compounds were characterized in the selected herbs using HPLC-MS/MS. MAO-B inhibitory activity and total phenolic content of the acquired herbs were compared with those of a prepared herbal formula consisting of a mixture of equal amounts of the four mentioned herbs.

Exposure to ionizing radiation usually results in cellular oxidative damage and may induce liver toxicity. The efficiency of the ethanol extracts of (EWF) and (EWR) leaves in alleviating γ-radiation-induced oxidative hepatotoxicity was herein explored. Proximate and macronutrient composition of the leaves was determined to establish reliable quality control criteria.

Over 100 species of the genus Salsola are distributed in dry, arid parts of Asia, Europe and Africa, of which many species are recognised as antifungal, anticancer, antihypertensive and anthelmintic agents. Egyptian Salsola received scant characterisation of either its phytochemical composition or its biological effects. In this study, the metabolite profiles of two Salsola species viz.

The chemical constituents and biological activities of the terrestrial Aspergillus flavipes MM2 isolated from Egyptian rice hulls are reported. Seven bioactive compounds were obtained, of which one sterol: ergosterol (1), four butyrolactones: butyrolactone I (2), aspulvinone H (3), butyrolactone-V (6) and 4,4'-diydroxypulvinone (7), along with 6-methylsalicylic acid (4) and the cyclopentenone analogue; terrien (5). Structures of the isolated compounds were deduced by intensive studies of their 1D & 2D NMR, MS data and comparison with related structures.

The acaricidal (miticidal) activity of 90% ethanolic extracts of leaves and stem bark of Swietenia mahogani and Swietenia macrophylla were tested against Varroa destructor mite. Four concentrations were used over two different time intervals under laboratory and field conditions. In general, it was noticed that the acaricidal effect based on mortality and LC(50) of all tested extracts against the Varroa mite was concentration and time dependant.
