Abstract

The medicinal plant Phyllanthus emblica Linn. has been recognized for its health-beneficial properties and has a long history of cultivation in ancient China and India. However, its effects and main mechanism in high-fat diet (HFD)-induced metabolic syndrome (MetS) have not been revealed yet. According to our findings, emblica fruit powder (EFP) through the freeze-drying process was able to modulate the composition of the intestinal microbiota, with a significant increase in the beneficial bacteria genera Lactobacillus and Turicibacter. In addition, fecal metabolite profiling revealed that 20 metabolites were deferentially expressed, which were mainly organic acids, amino acids, and their derivatives. They are primarily enriched in the biological process of lipid metabolism, including the metabolism process of cholic acid, glycerophospholipid, and α-linoleic acid. Subsequent qPCR testing of the liver tissue suggested that the regulatory effects of EFP in HFD mice may stem from its influence on the expression levels of over 20 key genes involved in host metabolic processes. In conclusion, EFP is able to alleviate the MetS caused by HFD, and this positive impact may be partially through the regulation of the “gut-liver axis.” Consequently, EFP holds potential as a functional food ingredient for the prevention and management of MetS.

冬青果冻干粉中功能成分对 MetS 小鼠模型的调节作用及其机制
药用植物黄皮(Phyllanthus emblica Linn.)被认为具有有益健康的特性,在古代中国和印度有着悠久的栽培历史。然而,其在高脂饮食(HFD)诱导的代谢综合征(MetS)中的作用和主要机制尚未揭示。根据我们的研究结果,通过冷冻干燥工艺制成的冬青果粉(EFP)能够调节肠道微生物群的组成,其中乳酸杆菌属和湍流杆菌属的有益菌显著增加。此外,粪便代谢物分析表明,有 20 种代谢物被递延表达,主要是有机酸、氨基酸及其衍生物。它们主要富集在脂质代谢的生物过程中,包括胆酸、甘油磷脂和α-亚油酸的代谢过程。随后对肝脏组织进行的 qPCR 检测表明,EFP 对高脂蛋白胆固醇小鼠的调控作用可能源于其对 20 多个参与宿主代谢过程的关键基因表达水平的影响。总之,EFP 能够缓解高氟日粮引起的 MetS,而这种积极影响可能部分是通过调节 "肠肝轴 "产生的。因此,EFP 有潜力成为预防和控制 MetS 的功能性食品配料。

期刊介绍: The Journal of Food Biochemistry publishes fully peer-reviewed original research and review papers on the effects of handling, storage, and processing on the biochemical aspects of food tissues, systems, and bioactive compounds in the diet. Researchers in food science, food technology, biochemistry, and nutrition, particularly based in academia and industry, will find much of great use and interest in the journal. Coverage includes: -Biochemistry of postharvest/postmortem and processing problems -Enzyme chemistry and technology -Membrane biology and chemistry -Cell biology -Biophysics -Genetic expression -Pharmacological properties of food ingredients with an emphasis on the content of bioactive ingredients in foods Examples of topics covered in recently-published papers on two topics of current wide interest, nutraceuticals/functional foods and postharvest/postmortem, include the following: -Bioactive compounds found in foods, such as chocolate and herbs, as they affect serum cholesterol, diabetes, hypertension, and heart disease -The mechanism of the ripening process in fruit -The biogenesis of flavor precursors in meat -How biochemical changes in farm-raised fish are affecting processing and edible quality
