Phenolic compounds are parts of secondary metabolites mostly found in plant species with enormous structural diversities. They can exist as glycosides or aglycones; matrix or free-bound compounds; and comprising mostly polymerized or monomer structures. Additionally, these compounds are not universally dispensed within plants with varied stability. This has contributed to challenging extraction processes; implying that employing a single step or inappropriate extraction technique might change the recovery of phenolic components from the plant samples. Hence, it is important to select an appropriate extraction method so as to recover the targeted phenolic compounds. This is will helps to recover substantial yields from the sample matrix. Therefore, this review mainly focuses on the phenolic compounds and several methods of extraction that are used to obtaining them from plant materials. These extraction methods includes both conventional and unconventional techniques.
酚类化合物是次生代谢产物的一部分，大多存在于结构多样性巨大的植物物种中。它们可以以糖苷或苷元的形式存在；以基质或游离结合化合物的形式存在；并且大多由聚合或单体结构组成。此外，这些化合物在植物中的分布并不普遍，稳定性也各不相同。这使得提取过程具有挑战性；这意味着采用单一步骤或不适当的提取技术可能会改变从植物样品中回收酚类成分的情况。因此，选择合适的提取方法以回收目标酚类化合物很重要。这将有助于从样品基质中获得大量产量。因此，本综述主要关注酚类化合物以及用于从植物材料中获取它们的几种提取方法。这些提取方法包括传统技术和非传统技术。
