Plant-based milk is rich in polyunsaturated fatty acids， polyphenols and other bioactive compounds. This study investigated the effect of three plant-based milk (flaxseed milk， oat milk and soy milk) on the ceftriaxone-induced intestinal disorders， and compared the regulation patterns associated with gut microbiome and metabolome. The results showed plant-based milk alleviated the ceftriaxone caused cecum swelling， colonic tissue damage and intestinal microecological disorders. Meanwhile， administered plant-based milk decreased levels of pro-inflammatory cytokine (tumor necrosis factor (TNF-α)， interleukin (IL-6)， interleukin (IL-1β) and oxidative stresses (malondialdehyde (MDA) and myeloperoxidase (MPO) in the colon， as well as increasing the levels of tight junction proteins (Occludin， Claudin-1， and ZO-1) in the colon. Moreover， administration of plant-based milk modulated the intestinal microbiota by promoting the relative levels of beneficial bacteria (Bifidobacterium)， and inhibiting the harmful bacteria genus (Enterococcus). Furthermore， plant-based milk treatment significantly modulated glycerophospholipids metabolism (e.g. glycerophosphocholine) and arachidonic acid metabolism (e.g. prostaglandin G2 and arachidonic acid) in the serum. In conclusion， plant-based milk could alleviate antibiotic-related imbalance of barrier function damage， gut microbiota disorders and the reduction of metabolic disorders， which lays a foundation for exploring anti-inflammatory and intestinal micro-ecological approach to plant-based milk.

oil from Camellia oleifera Abel. seed is a popular edible oil in Asia, which has gained much attention for itsmedicinal applications on relieving various inflammation, however, the mechanism is still unknown. The presentstudy was to investigate the gastroprotective effect of camellia oil against ethanol-induced gastric mucosal injuryin mice. The results showed that camellia oil pretreatment significantly reduced gastric ulcer injury. A remarkableinhibited oxidative stress by reducing the concentration of malondialdehyde and a significant decrease of thelevels of pro-inflammatory factors in gastric tissue were observed in camellia oil pretreated group. In addition,camellia oil improved the diversity of gut microbiota and changed the community structure and composition byincreasing Bacteriodes and Dorea. And the feces metabolomics found that metabolism of cofactors and vitamins,and lipid, carbohydrate and amino acid metabolism were modulated by admiration of camellia oil. Takentogether, the findings of this study suggested that camellia oil could ease the ethanol-induced gastric mucosalinjury via the improvement of anti-oxidant and anti-inflammatory status, as well as the regulation of gutmicrobiota and its metabolites.

Flaxseed lignan macromolecules (FLM) are a class of important secondary metabolites in flaxseed， which have been widely concerned due to their biological and pharmacological properties， especially for their antioxidative activity. For the composition and structure of FLM， our results confirmed that ferulic acid glycoside (FerAG) was directly ester-linked with herbacetin diglucoside (HDG) or pinoresinol diglucoside (PDG)， which might determine the beginning of FLM biosynthesis. Additionally， p-coumaric acid glycoside (CouAG) might determine the end of chain extension during FLM synthesis in flaxseed. FLM exhibited higher antioxidative activity in polar systems， as shown by its superior DPPH free radical scavenging capacity compared to the ABTS free radical scavenging capacity in non-polar systems. Moreover， the antioxidative activity of FLM was found to be highly dependent on its composition and structure. In particular， it was positively correlated with the number of phenolic hydroxyl groups (longer FLM chains) and inversely related to the steric hindrance at the ends (lower levels of FerAG and CouAG). These findings verified the potential application of FLM in non-polar systems， particularly in functional food emulsions.
