species are promising potential sources of natural antioxidants, owing to their high polyphenol content. In addition, increasing scientific and epidemiological evidence have associated consumption of foods rich in polyphenols with health benefits such as decreased risk of cardiovascular diseases mediated through anti-inflammatory effects. The complex and diverse nature of polyphenols and the huge variation in their levels in commonly consumed herbs make their analysis challenging. Innovative robust analytical tools are constantly developing to meet these challenges. In this review, we present advances in the state of the art for the identification and quantification of polyphenols in species. Novel chromatographic techniques that have been employed in the past decades are discussed, ranging from ultra-high-pressure liquid chromatography to hyphenated spectroscopic methods, whereas performance characteristics such as selectivity and specificity are also summarized.
由于其高多酚含量，物种是天然抗氧化剂的有前景的潜在来源。此外，越来越多的科学和流行病学证据表明，食用富含多酚的食物具有健康益处，例如通过抗炎作用降低心血管疾病风险。多酚的复杂多样性质以及它们在常见草药中的含量巨大差异使得对其进行分析具有挑战性。不断开发创新的强大分析工具以应对这些挑战。在本综述中，我们介绍了用于鉴定和定量物种中多酚的最新技术进展。讨论了过去几十年中使用的新型色谱技术，从超高压液相色谱到联用光谱方法，同时还总结了诸如选择性和特异性等性能特征。
