摘要:

林源次生代谢物的开发与利用是发挥森林“钱库”作用的重要途径。枳实黄酮是一类天然的林源黄酮类化合物,因具有重要的生物活性而被广泛应用于食品、药品等领域。然而,当前枳实提取物产业仍存在资源利用率较低、枳实黄酮生物活性作用机制不明以及水溶性差、生物利用度低等瓶颈问题,严重制约产业的可持续发展。基于此,本文综述了枳实黄酮的提取方法,提出了强化质量传递过程与揭示提取机理的策略;评述了枳实黄酮的主要生物活性与作用机制;梳理了通过化学结构修饰或包埋技术进行改性增加其利用价值的途径。同时,对开展枳实黄酮的研究提出了建议:1)在提高枳实资源利用率方面可采用多种技术联合或多组分提取的方法实现枳实黄酮的高效提取,建立质量传递模型并结合表征技术揭示提取过程中的物质迁移规律;2) 在生物活性及作用机制研究方面可以通过实验与计算化学相结合的手段深入研究枳实黄酮的化学结构与生物活性之间的构效关系,揭示其生物活性作用的分子机制;3)在枳实黄酮的改性方面可融合计算化学手段精准设计改性策略并诠释改性机制。

Abstract:

The exploitation and utilization of secondary metabolites of forest source is an important approach to play the forest as "treasure houses". Natural forest-derived flavonoids from Citrus aurantium which exhibit significant biological activities have been widely used in the fields of food and medicine. However, some bottleneck problems such as low resource utilization rate, unclear bioactivity mechanism, poor water solubility and low bioavailability, seriously restrict the sustainable development of the industry. This paper reviews the extraction, bioactivity and modification of flavonoids from Citrus aurantium. The extraction methods of the flavonoids were reviewed, while the strategies to strengthen the quality transfer process and the extraction mechanism were proposed. The main biological activities and potential mechanisms of the flavonoids were introduced, and the strategies to increase the flavonoids utilization value through chemical structure modification or embed technology were summarizeed. Meanwhile, the suggestions for future research were proposed. 1) The multi-extraction technology or multi-component extraction methods can be utilized to achieve efficient extraction of the flavonoids to improve the utilization efficiency of resources, and the migration behavior of substances during the extraction process may be revealed with the help of mass transfer models and characterization techniques. 2) The structure-activity relationship between chemical structure and biological activity can be further studied by means of experiment combining with computational chemistry to expound biological activities and their mechanisms. 3) The computational chemical methods can be used to accurately design modification strategies and interpret modification machines to modify the flavonoids.
