The present study explored the influence of submerged fermentation with different lactic acid bacteria (LAB) as a pre-treatment of moringa leaves before the extraction of phenolic compounds via sonotrode. The sonotrode extraction was optimized using a Box-Behnken design and the optimal conditions found were: 25 % ethanol, 5 min and 100 % amplitude. Folin-reacting substances and antioxidant activity were measured on hydroalcoholic extracts obtained from fermented moringa leaves and, individual phenolic compounds were determined by HPLC-ESI-TOF-MS for the first time.

Tea is a widely consumed beverage worldwide due to its rich secondary metabolites. Gallotanin: 1-O-galloyl-6-O-luteoyl-α-D-glucose (GLAG) has strong antioxidant activity and good resistance to a wide range of bacteria and malaria. Despite its potential, there have been few reports on GLAG in plants.

Free fatty acids (FFAs) are important energy sources and significant for energy transport in the body. They also play a crucial role in cellular oxidative stress responses, following cell membrane depolarization, making accurate quantification of FFAs essential. This study presents a novel supercritical fluid chromatography-mass spectrometry (SFC-MS) method using selected ion recording in negative electrospray ionization mode, enabling rapid quantification of 31 FFAs within 6 min without derivatization.

Screening for inborn metabolic disorders (IMDs) in newborns is an important way to prevent serious metabolic and developmental difficulties that can result in lasting disabilities or even death. Electrospray ionization tandem mass spectrometry (MS/MS) provides an efficacious newborn blood spot screening (NBS) mechanism for analyzing dried blood spot specimens (DBSs) for biochemical markers for these conditions. Where possible, the elimination of derivatization in specimen preparation can simplify and streamline analysis.
