Onion peels are often discarded, representing an unlimited amount of food by-products; however, they a valuable source bioactive phenolics. Thus, we utilized UPLC-MS/MS to analyze the metabolomic profiles red (RO) and yellow (YO) onion peel extracts. The cytotoxic (SRB assay), anti-inflammatory (Griess antimicrobial (sensitivity test, MIC, antibiofilm, SP-SDS tests) properties were assessed in vitro. Additionally, histological analysis, immunohistochemistry, ELISA tests conducted investigate...

Berberine (BBR) is a known alkaloid that has verified its protective effects against ischemia/reperfusion (I/RN) lesion in multiple organs but poor oral bioavailability limited use. Despite the previous works, possible impact on warm hepatic I/RN-induced not clear. Accordingly, nanostructured lipid carrier of BBR (NLC BBR) was developed for enhancing efficiency and to inspect mechanistic I/RN.NLC formula evaluated pharmaceutically. Wistar rats were orally pre-treated with either or NLC (100...

Reusing food waste is becoming popular in pharmaceutical industries. Watermelon (Citrullus lanatus) rind commonly discarded as a major solid waste. Here, the vitro cytotoxic potential of watermelon extracts was screened against panel human cancer cell lines. Cell cycle analysis used to determine induction death, whereas annexin V-FITC binding, caspase-3, BAX, and BCL-2 mRNA expression levels were degree apoptosis. VEGF-promoting angiogenesis migration also evaluated. Moreover, identification...

Abstract Traditionally, Bidens pilosa L. is an edible herb utilized for various ailments. The study accomplished a complete analysis of B. extract including UPLC/T-TOF–MS/MS, GC–MS, and in vitro antiproliferative activity, addition to molecular docking on kinase aldose reductase enzymes. From GC–MS analysis, the percentage identified unsaturated fatty acids (FAs) (11.38%) was greater than saturated FAs (8.69%), while sterols percent (39.92%) higher hydrocarbons (6.6%). Oleic palmitic are...

Morin (MRN), a known natural flavonol, has demonstrated its shielding aptitude against ischemia/reperfusion (I/Re) lesion in various organs. Nonetheless, potential influence on hepatic I/Re-induced injury modulation not been fully elucidated. Consequently, the current study strived to investigate mechanistic maneuvering of MRN I/Re. Furthermore, effects Nrf2, TLR4, and NLRP3 proteins were evaluated via molecular docking studies.

Saussurea costus is a plant traditionally used for the treatment of several ailments. Our study accomplished UPLC/T-TOF-MS/MS analysis methanol extract roots (MESC), in addition to lipoidal matter determination and assessment its vivo hepatoprotective activity. In this study, we were able identify major metabolites MESC rather than previously known isolated compounds, improving our knowledge chemical constituents. The flavones apigenin, acacetin, baicalein, luteolin, diosmetin, flavonol...
