Walnut dreg protein hydrolysates(WDPHs)exhibit a variety of biological activities,however,the cyclooxygenase-2(COX-2)inhibitory peptide of WDPHs remain unclear.The aim of this study was to rapidly screen for such peptides in WDPHs through a combination of in silico and in vitro analysis.In total,1262 peptide sequences were observed by nano liquid chromatography/tandem mass spectrometry(nano LC-MS/MS)and 4 novel COX-2 inhibitory peptides(AGFP,FPGA,LFPD,and VGFP)were identified.Enzyme kinetic data indicated that AGFP,FPGA,and LFPD displayed mixed-type COX-2 inhibition,whereas VGFP was a non-competitive inhibitor.This is mainly because the peptides form hydrogen bonds and hydrophobic interactions with residues in the COX-2 active site.These results demonstrate that computer analysis combined with in vitro evaluation allows for rapid screening of COX-2 inhibitory peptides in walnut protein dregs.

Moringa oleifera Lam. (M. oleifera Lam) is a Moringa genus in the Moringaceae family that is high in nutrients and has a wide range of applications. Phenolic compounds are widely found in plants and have various health benefits for the human body. With its high content and wide variety of phenolic compounds， M. oleifera Lam has been widely studied for its health benefits. The phenolic compounds in M. oleifera Lam (MOPCs) can be a potential source of functional food ingredients in pharmaceutical and industrial applications. Numerous studies have shown that MOPCs have antioxidant， anti-obesity， anti-diabetic， and antibacterial effects. Although the research on MOPCs has been gradually increasing， the extraction， isolation， identification， biological activities， and comprehensive application of MOPCs need a more systematic summary and generalization. Therefore， this paper reviews the isolation and extraction methods， structure identification， biological activities， and comprehensive applications to provide a further reference for the research and application of MOPCs.

Diabetes mellitus(DM)is a chronic metabolic disease characterized by hyperglycemia,which poses a serious threat to human health.Moringa oleifera Lam.is a medicinal and edible plant with various physiological functions.However,its main hypoglycemic components and mechanisms are still unclear.In this study,network pharmacology and bioinformatics were used to analyze the potential bioactive substances of M.oleifera leaf extract(MOLE)and its hypoglycemic mechanism.Studies have shown that MOLE has the effect of increasing glucose consumption in insulin resistant-HepG2 cells.MOLE was found to contain 975 compounds by ultrahigh performance liquid chromatography-mass spectrometry(UHPLC-MS).Network pharmacology analysis indicated that the main active component was robinetin and the identified core genes were AKT1 and GAPDH.KEGG pathway enrichment analysis showed that the hypoglycemic effect of MOLE may be closely related to the PI3K-Akt signaling pathway.This study revealed the possible active components and mechanisms of action of M.oleifera for hypoglycemia,laying the theoretical foundation for subsequent studies.

This aim of this study was to rapidly screen for such peptides in WDPHs through a combination of in silico and in vitro analysis. In total， 1262 peptide sequences were observed by nano LC-MS/MS and four novel COX-2 inhibitory peptides (AGFP， FPGA， LFPD， and VGFP) were identified for the first time. Enzyme kinetic data indicated that AGFP， FPGA， and LFPD displayed mixed-type COX-2 inhibition， whereas VGFP was a non-competitive inhibitor. This is mainly because the peptides form hydrogen bonds and hydrophobic interactions with residues in the COX-2 active site.
