The antioxidant potential and phenolic profile of infusions prepared with cherry stems from different commercial brands were studied. The phenolic profile of each infusion was characterized by UHPLC-ESI-QTOF-MS and 44 phenolic compounds belonging to eight distinct classes (hydroxybenzoic acids, hydroxycinnamic acids, phenylpropanoic acids, flavan-3-ols, flavonols, flavanones, flavones and isoflavones) were tentatively identified. For the first time, salicylic acid was identified in cherry stem infusions. In cell-based assays, all the infusions tended to inhibit lipid peroxidation and presented no cytotoxicity. Significant differences (p < 0.05) were found between a sample sold in bulk (lower antioxidant activity by DPPH˙ inhibition, ferric reducing antioxidant power, and oxygen radical absorbance capacity assays; lower amounts of total phenolics and flavonoids and a different quantitative phenolic profile) and samples sold in packages. These, in turn, were very similar to each other and revealed a high antioxidant potential and a very rich phenolic profile. These results reflect not only the antioxidant potential of cherry stem infusions but also the need to globally harmonize the control and regulation of herbal products in order to ensure in the market products with high quality, safety and efficacy.

樱桃茎浸液：通过UHPLC-ESI-QTOF-MS进行的抗氧化剂潜力和酚类分析

研究了来自不同商业品牌樱桃干的浸提液的抗氧化潜力和酚类特征。通过UHPLC-ESI-QTOF-MS对每种输注液中的酚类进行了表征，分别归类为8种不同类别的44种酚类化合物（羟基苯甲酸，羟基肉桂酸，苯基丙酸，黄烷-3-醇，黄酮醇，黄烷酮，黄酮和异黄酮）。初步确定。首次在樱桃茎浸液中鉴定出水杨酸。在基于细胞的测定中，所有输注都倾向于抑制脂质过氧化并且没有细胞毒性。散装出售的样品之间存在显着差异（p <0.05）（通过DPPH˙抑制作用降低了抗氧化活性，还原铁的抗氧化能力以及氧自由基吸收能力的测定）；总酚和类黄酮的含量较低，并且酚类的定量数量不同），并且样品以包装形式出售。这些反过来彼此非常相似，并且显示出高的抗氧化潜力和非常丰富的酚醛特性。这些结果不仅反映了樱桃茎浸液的抗氧化潜能，而且反映了在全球范围内协调草药产品的控制和调节以确保市场上产品具有高质量，安全性和有效性的需求。
