Abstract

Less research has been conducted on the association between camellia oil's (CO) phenolic composition and antioxidant capability. In this study, the phenolic profile of CO and its connection to antioxidant capacity were examined utilizing a combination of widely-targeted phenolic metabolomics and multivariate statistical analysis. A total of 751 phenolics were discovered. The WGCNA was used to link phenols to antioxidants, yielding 161 antioxidant-related phenols from the blue module. In response to several antioxidant assays, 59 (FRAP), 59 (DPPH), and 53 (ABTS) phenolics were identified as differential phenolic markers (DPMs). Further stepwise multiple linear regression revealed six DPMs that substantially influenced the antioxidant capacities. Nine metabolic pathways and their associated network mechanisms for the most significant phenolics were developed. This study sheds light on the phenolic content of CO, elucidates their role in antioxidant activity, and lays the groundwork for improving extraction techniques and generating improved product.

山茶油中的酚类成分及其相关抗氧化特性分析。

关于山茶油（CO）酚类成分与抗氧化能力之间关系的研究较少。在这项研究中，研究人员结合广泛的酚代谢组学和多元统计分析，对山茶油的酚类成分及其与抗氧化能力的关系进行了研究。共发现了 751 种酚类物质。利用 WGCNA 将酚类与抗氧化剂联系起来，从蓝色模块中得到了 161 种与抗氧化剂相关的酚类。在几种抗氧化测定中，59 种（FRAP）、59 种（DPPH）和 53 种（ABTS）酚类被确定为差异酚类标记（DPMs）。进一步的逐步多元线性回归发现，有六种 DPM 对抗氧化能力有重大影响。为最重要的酚类物质建立了九条代谢途径及其相关网络机制。这项研究揭示了一氧化碳中的酚类物质含量，阐明了它们在抗氧化活性中的作用，为改进提取技术和生产改良产品奠定了基础。

期刊介绍： No subject pertains more to human life than nutrition. The aim of Frontiers in Nutrition is to integrate major scientific disciplines in this vast field in order to address the most relevant and pertinent questions and developments. Our ambition is to create an integrated podium based on original research, clinical trials, and contemporary reviews to build a reputable knowledge forum in the domains of human health, dietary behaviors, agronomy & 21st century food science. Through the recognized open-access Frontiers platform we welcome manuscripts to our dedicated sections relating to different areas in the field of nutrition with a focus on human health. Specialty sections in Frontiers in Nutrition include, for example, Clinical Nutrition, Nutrition & Sustainable Diets, Nutrition and Food Science Technology, Nutrition Methodology, Sport & Exercise Nutrition, Food Chemistry, and Nutritional Immunology. Based on the publication of rigorous scientific research, we thrive to achieve a visible impact on the global nutrition agenda addressing the grand challenges of our time, including obesity, malnutrition, hunger, food waste, sustainability and consumer health.
