![]() showed that Ellagitannins and UVA radiation were proved to be efficient in biofortify strawberry agro-industrial by-products, significantly improving the phenolic compounds content and their bioactive properties with adequate bioaccessibility, adding value to the strawberry agro-industrial by-products. In recent years, it has become a major development trend in enhancing the activity of phenolic compounds through biotic or abiotic stress ( 5, 6), which is of great significance for the extension of the food industry chain. A thorough understanding of phenolic components among different species may provide scientific guidance for better enrichment and extraction of specific phenolic compounds and benefit the extension of the value chain of functional foods. fruit, as a functional fruit, was also rich in health-promoting phytonutrients and bioactive compounds, such as flavonoids, phenolic acids, vitamins, carotenoids, pectins, and fatty acids. reported that four phenolic classes with 316 phenolic metabolites were identified in white radish. found that isoflavones, sinapic acid derivatives, catechin and epicatechin, phenolic alcohols, chlorogenic acid, and lignans were the main phenolic compounds in soybean, rapeseed, peanut skin, olive, sunflower seed, sesame and flaxseed, respectively. The metabolomics approaches based on mass spectrometry can achieve comprehensive extraction and determination of different phenolic compounds. ![]() Phenolic compounds are widely distributed in vegetables, fruits and grains ( 4). Therefore, the novel technologies for enrichment, extraction, and determination of phenolic compounds have received widespread attention. However, they cannot be synthesized in the human body and need to be ingested through external sources ( 3). Due to the large amount of active phenolic hydroxyl groups in phenolics, they have a strong ability to scavenge free radicals and have various physiological and biochemical functions, including anti-cancer, anti-tumor, anti-aging, and other health-promoting functions ( 2). Phenolic compounds, a class of plant secondary metabolites with high biological activity, are mainly composed of flavonoids, phenolic acids, and anthocyanins ( 1).
