Nowadays due to the concern with the environmental impact of analytical techniques and in order to reduce the ecological footprint there is a tendency to use more efficient and faster procedures that use a smaller amount of organic solvents. Polyphenols have been widely studied in plant-based matrices due to their wide and potent biological properties; however there are no standardized procedures both for sample preparation and analysis of these compounds. The second of a two-part review will carry out a critical review of the extraction procedures and analytical methods applied to polyphenols and their selection criteria over a wide range of factors in relation to commerce-associated, environmental, and economic factors. It is foreseen that in the future the analysis of polyphenols in plant-based matrices includes the use of techniques that allow the simultaneous determination of different subclasses of polyphenols using fast, sophisticated, and automated techniques that allow the minimal consumption of solvents.
如今，由于人们关注分析技术对环境的影响，并为了减少生态足迹，人们倾向于使用更高效、更快的方法，这些方法使用的有机溶剂更少。由于其广泛而强大的生物特性，多酚已在植物基质中得到广泛研究；然而，对于这些化合物的样品制备和分析，既没有标准化的程序。这是两部分综述中的第二部分，将对多酚的提取程序和分析方法进行批判性回顾，并针对与商业相关的、环境的和经济的因素，对其选择标准进行广泛的评估。可以预见，在未来，植物基质中多酚的分析将包括使用允许同时测定不同类多酚的技术，使用快速、复杂和自动化的技术，最大限度地减少溶剂的消耗。
