Summary: This study investigated the changes in polyphenol content during pumpkin processing and comprehensively characterized and quantified the phenolic compounds using LC-ESI-QTOF-MS/MS and HPLC-PDA. The results showed that pumpkin seeds and skins had the highest total phenolic content and total antioxidant capacity, while separated pumpkin puree had a higher total condensed tannins content. Epicatechin and catechin were found to be the most abundant phenolic compounds in pumpkin seeds and skins. This study highlights the potential of pumpkins as a source of antioxidant polyphenols.

Summary: This paper examines the adsorption of methylene blue (MB) and crystal violet (CV) dyes onto Bauhinia forficata residual fruit powder (BFRFP) as a potential adsorbent. The results show that BFRFP has a higher affinity for CV dye, and it can be a competitive material for removing MB and CV dyes from polluted water. A physical model is used to interpret the adsorption mechanisms, indicating the presence of physical interactions during the adsorption process.

Summary: This study proposes derivatization reagents based on azobenzene, AzoB and AzoC, for LC-ESI-MS analysis of free amino acids in fermented beverages and juices. The results show that AzoB can be used for targeted and non-targeted analysis, while AzoC has advantages such as fast reaction and good reactivity with secondary amines but is affected by side products for quantitation.

Summary: This study validated an alternative microbiological assay for quantitation of posaconazole in bulk and investigated its stress stability, showing susceptibility to degradation factors. Three major degradation products of posaconazole were identified, with first-order kinetics observed for photolytic decomposition. The microbiological method was proven to be equivalent to physico-chemical ones, and impurities found in posaconazole were described for the first time in raw material studies.

Summary: The stability of the antibiotic doripenem was evaluated by LC-ESI-Q-TOF method, revealing six degradation products under stress conditions and the formation of a major degradation product through cleavage of the beta-lactam ring under hydrolytic conditions. Additionally, oxidation of the drug using H2O2 led to the formation of three new degradation products. The study provides insight into the degradation behavior of doripenem and its important antibiotic class.
