Theoretically, lactic acid bacteria (LABs) could degrade polyphenols into small molecular compounds. In this study, the biotransformation of lotus seedpod and litchi pericarp procyanidins by (), (), (), and 06 () were analysed. The growth curve results indicated that procyanidins did not significantly inhibit the proliferation of LABs. Ultra-high-performance liquid chromatography high-resolution mass spectrometry (UPLC-HRMS) revealed that procyanidin B2 and procyanidin B3 in lotus seedpod decreased by 62.85% and 25.45%, respectively, with metabolised, while kaempferol and syringetin 3-O-glucoside content increased. Although bioconversion did not increase the inhibitory function of procyanidins against glycosylation end-products in vitro, the 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate) free radical scavenging capacity and ferric reducing antioxidant power of litchi pericarp procyanidins increased by 157.34% and 6.8%, respectively, after biotransformation. These findings may inspire further studies of biological metabolism of other polyphenols and their effects on biological activity.

Metabolic syndrome (MetS) poses considerable toxicological risks due to its association with an increased likelihood of metabolic dysfunction-associated steatotic liver disease (MASLD), and is characterized by hypertension, hyperglycemia, dyslipidemia, and obesity. This study aimed to investigate the therapeutic potential of flavonoid-rich lotus seedpod extract (LSE) in alleviating MetS and MASLD-related hepatic disturbances. In vivo, mice subjected to a high-fat diet (HFD) and streptozotocin (STZ) injection were supplemented with LSE or simvastatin for 6 weeks.

The integration of photothermal de-icing and micro/nanostructured anti-icing technologies into a surface is regarded as a promising solution to solve ice accretion aggravated. Unfortunately, light-dependent heat effect and large-scale production of micro/nano building still challenge the anti-icing ability and applications for real-world. Herein, a stick-and-play film embedded with bioinspired thermal-management cells is developed.

Polyphenols have potent antioxidant properties, but are easily degraded in the gastrointestinal tract, greatly limiting their application as dietary supplements. Therefore, the composition changes of lotus seedpod oligomeric procyanidins (LSOPC) in the gastrointestinal digestion, colonic fermentation and their absorption in Caco-2 cell monolayer were studied. The extracted LSOPC were identified using UPLC-Q-Exactive/MS, and a total of 47 compounds were identified.

Effective removal of phosphorus from water is crucial for controlling eutrophication. Meanwhile, the post-disposal of wetland plants is also an urgent problem that needs to be solved. In this study, seedpods of the common wetland plant lotus were used as a new raw material to prepare biochar, which were further modified by loading nano La(OH) particles (LBC-La).
