To solve the problem of the lack of reference material （RM） for determination of allergenic ingredients in food， a RM of cashew nut powder was developed in the study. Cashew nut powder was prepared from cashew nut kernel by selecting， cleaning， crushing， n-hexane degreasing and sieving treatment. The reliability and traceability of RM was verified using real-time quantitative polymerase chain reaction （qPCR） and phylogenetic tree analysis. The cashew nut powder RM showed good homogeneity， and good stability under long-term storage at 4℃ and short-term simulated transportation from -20℃ to 45℃. The RM was determined jointly by 8 collaborative laboratories， and the characteristic CTvalue was 24.732， and the extended uncertainty was 1.052 （k=2）. The RM was applied to verify the amplification efficiency （E）and the limit of detection （LOD） for qPCR assay， and showed good applicability. The RM could be used for method validation and quality control， for the determination of allergenic ingredients in food mixed with trace amounts of cashew nut.

Type 2 diabetes (T2D) presents a significant health challenge， underscoring the need for functional foods and nutraceutical hypoglycemic bioactive peptides for its prevention. This study investigates the potential of proteolytic hydrolysate from artificially cultivated Chinese giant salamander (CGS) meat， a rich protein source， as a preventive strategy for T2D. We produced a CGS meat hydrolysate (CGSh) and demonstrated its ability to inhibit the T2D drug target DPP-IV through in vitro assays. We identified five peptides (WRPPDH， WAPPSKD， IPDSPF， IPEMIF， and VPIAVPT) with high DPP-IV inhibitory activity in CGSh， suggesting its potential antidiabetic effects. In vivo experiments showed that CGSh effectively reduced insulin resistance in mice induced with a high-fat diet， as evidenced by a slower increase in blood glucose levels and a decreased HOMA-IR index. 16S rRNA sequencing analysis revealed that CGSh improved gut microbial homeostasis， promoting beneficial microorganisms and reducing harmful bacteria. Metabolomic analyses identified an increase in valeric acid levels and highlighted nine potential biomarker metabolites. By inhibiting metabolic pathways such as AGE-RAGE， CGSh may also prevent diabetic complications and reduce inflammation. These findings suggest that CGSh has a promising hypoglycemic effect， making it a potential functional food ingredient for T2D prevention and treatment.

Podostemaceae(riverweed family),one of the largest aquatic plant families in the world,comprises about 350 species in 51 genera placed in three subfamilies,Podostemoideae,Weddellinoideae,and Tristichoideae(Koi et al.,2022).Most Podostemaceae genera(~38)are monotypic or oligotypic,with a high level of endemism(Koi et al.,2018,2022).Members of Podostemaceae adhere to rocks in fast-flowing rivers,streams,or waterfalls in the subtropics and tropics(Koi et al.,2018).As an adaptation to fastrunning currents,the morphological structure of river-weeds tends to be extremely reduced,including a loss or reduction of primary shoots or roots(Koi and Kato,2007).The vegetative mass of these plants resembles lichens or bryophytes,and are thus known commonly as“dream bryophytes”(Philbrick and Retana,1998).Podostemaceae plants flower when the water level drops during the dry *** recent years,anthropogenic factors and climate change have severely affected river weed habitats,decreasing populations of these plants.
