Depression is a prevalent mental disorder with limited effective treatments， posing a significant global issue. This study explored L-theanine and geniposide， key components in "food-medicine homology" materials， to determine if their combination (TG) could alleviate depression-like behaviors and hippocampal neuronal damage in a chronic unpredictable mild stress (CUMS) mouse model. Male C57BL/6J mice were divided into control， CUMS model， and CUMS+TG groups with varying doses. The CUMS group displayed depression-like behaviors， including reduced activity and sucrose preference. TG treatment partially reversed these changes， significantly increasing antioxidant enzyme activities， decreasing pro-inflammatory cytokine levels， and improving neuromodulator levels. RNA-seq analysis identified the transthyretin (TTR) gene， upregulated in the model group but downregulated after TG treatment. TG treatment modulated intestinal microbiota composition compared to the CUMS group， including increased Firmicutes， reduced Bacteroidetes and Prevotella， and variable changes in Bifidobacterium abundance. In conclusion， our study indicates that CUMS exposure upregulates stress hormones and TTR expression， associated with neuroinflammation， oxidative stress， monoamine depletion， depression-like behaviors， and intestinal microbiota dysbiosis. TG treatment alleviates these effects and modulates intestinal microbiota， suggesting L-theanine and geniposide’s potential as a novel depression therapy.

Wheat bran, a principal byproduct of flour milling, stands as an abundant source of dietary fiber, yet its economic potential remains under-exploited in current forage applications. Arabinoxylan(AX), constituting the core of dietary fiber, emerges as a versatile compound with multifaceted functionalities. Its nutritional significance,coupled with its role in cereal food processing, has prompted a surge of studies focusing on the valorization of wheat bran AX. Moreover, the hydrolyzed derivative, arabinoxylan oligosaccharides(AXOS), demonstrates prebiotic and antioxidant properties, offering potential avenues to mitigate the risk of chronic diseases. This review summarizes current knowledge on the valorization of wheat bran AX in terms of the processing and nutritional properties of AX. Moreover, multiple novel applications of AX in the materials area, including biodegradable food packaging films, delivery of bioactive substances as nanoparticles, and the manufacture of food emulsifiers, are also highlighted to extend the utilization of AX. This review underscores the immense potential of wheat bran AX, advocating for its exploitation not only as a nutritional asset but also as a primary ingredient in advanced materials. The synthesis of nutritional and materials perspectives accentuates the multifaceted utility of wheat bran AX, thereby paving the way for sustainable valorization pathways. By unraveling the latent potential within AX, this paper advocates for the holistic and sustainable utilization of wheat bran in diverse, value-added applications.

Medicinal and dietary plants provide numerous nutritional and functional compounds and also have various potential health benefits to humanity. The specific and efficient techniques for accurate identification of nutritional compounds and functional metabolites is crucial for the development of functional foods from medicinal and dietary plants. Nuclear magnetic resonance (NMR) and mass spectrometry (MS) are indispensable and essential technologies that provide an unsurpassed wealth of untargeted identification， quantitative and qualitative analysis， and structural information in the study of food and plant products. In the past decade， the rapid development of modern analytical technology has led to the emergence of new approaches and strategies for natural products discovery. Especially the application of novel NMR- and MS-based identification and dereplication strategies aided by artificial intelligence and machine learning algorithms have brought about a significant shift in the natural products discovery process. These developments and changes in the natural products filed have given us insights into how to accurately target and mining nutritional， functional， and bioactive compounds. Thus， we have summarized recent research on novel NMR and MS based strategies and methods focusing on functional compounds， accurate identification and efficient discovery mainly in medicinal and dietary plants. This review could provide a comprehensive perspective for a better understanding of novel strategies and methods based on NMR and MS technologies， which could provide valuable insights and ideas for functional compounds mining.
