Linalool as a key component in strawberry volatile organic compounds (VOCs) modulates gut microbiota, systemic inflammation, and glucolipid metabolism. Food Chem 2024; 460:140361.

Abstract
Strawberries are rich in volatile organic compounds (VOCs), which are increasingly recognized as potential health-promoting factors. This study explored the health effects of intaking strawberry VOC extract and its dominant terpene, linalool. The results indicated that linalool and strawberry VOC extract significantly increased the abundance of beneficial bacteria like Lactobacillus, Bacillus, and Alistipes in mice. Moreover, mice treated with linalool and strawberry VOC extract exhibited notable reductions in serum pro-inflammatory cytokines; interleukin IL-6 decreased by 14.5% and 21.8%, respectively, while IL-1β levels decreased by 9.6% and 13.4%, respectively. Triglyceride levels in the treated groups were reduced by 38.3% and 58.1%, respectively. Spearman's correlation analysis revealed that Bacillus negatively correlated with glucolipid indices, and Bifidobacterium and Dubosiella negatively correlated with inflammatory factors, indicating that alterations in glucolipid metabolism might be associated with the regulation of gut microbiota and systemic inflammation.

You YL, Choi HS. Nootkatone (NK), a grapefruit-derived aromatic compound, inhibited lipid accumulation by regulating JAK2-STAT signaling and antioxidant response in adipocyte. Food Sci Biotechnol 2024; 33:2631-2641. [PMID: 39144189 PMCID: PMC11319697 DOI: 10.1007/s10068-024-01522-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/20/2023] [Accepted: 01/05/2024] [Indexed: 08/16/2024] Open
Abstract
Nootkatone (NK) is an aromatic compound derived from grapefruit. This study aimed to investigate the inhibitory effect of NK on lipid accumulation and its underlying mechanism in adipocytes. NK effectively inhibited adipogenic lipid storage by downregulating C/EBPα and PPARγ, while upregulating KLF2, an early inhibitory factor, downregulating C/EBPβ, an early promoting factor. In addition, NK inhibited the JAK2-STAT signaling pathway by decreasing the phosphorylation of STAT3 and STAT5 in the early adipogenic stage. NK significantly reduced ROS generation while elevating antioxidant enzymes such as catalase and glutathione peroxidase. It activated NRF2-HO-1 signaling, responsible for antioxidant response, by increasing protein levels. Furthermore, NK regulated adipokines, increasing adiponectin and visfatin, while downregulating resistin. Collectively, NK inhibited adipogenic lipid accumulation through the suppression of JAK2-STAT signaling and the augmentation of antioxidant response. This study highlights the potential of NK as an edible agent to alleviate obesity and its associated metabolic diseases.
