In Mexico, plants are commonly used to alleviate various ailments, including controlling some chronic degenerative diseases through the regular consumption of decoctions, infusions, and teas. However, there is little scientific evidence consolidating traditional medicine within health systems. Therefore, this work determined the phytochemical profile of the most used plants to treat various ailments (Cedro rojo, Cancerina, Ortiguilla, Hierba de la golondrina, Hierba de arlomo) and their general consumption as infusions. Aqueous and ethanolic extracts were generated, while the phytochemical compound content in the extracts obtained was quantified. The results indicate that the ethanolic extracts showed the highest phenolic compound and tannin content, with the highest contents for Cedro rojo (831.04 mg L−1) and Cancerina (864.80 mg L−1). The antioxidant activity was also determined, and a significant difference was observed (p<0.05). The extracts with the highest antioxidant capacity were the ethanolic extracts ranging from 250 to 907 μMET mL−1, while the aqueous extracts ranged from 112 to 390 μMET mL−1. The compounds identified by high-performance liquid chromatography characterization on the aqueous extracts highlighted the presence of chlorogenic acid>cinnamic acid>quercetin. In ethanolic extracts, the presence of chlorogenic acid>cinnamic acid>quercetin>gallic acid>ferulic acid>coumaric acid was highlighted. The correlation between bioactive compounds, type of extract, and antioxidant activity suggests a significant affinity of these phytochemical compounds for the ethanol solvent. The results indicate that these plants are good sources of antioxidant phenolics and can be incorporated for use as functional beverages. However, more studies are needed to corroborate their beneficial effect.

瓜纳华托州彭贾莫的五种传统药用植物的抗氧化活性、总酚、单宁和类黄酮含量

在墨西哥,植物通常用于缓解各种疾病,包括通过经常食用煎剂、输液和茶来控制一些慢性退行性疾病。然而,几乎没有科学证据表明传统医学在卫生系统中得到巩固。因此,这项工作确定了最常用于治疗各种疾病的植物(Cedro rojo、Cancerina、Ortiguilla、Hierba de la golondrina、Hierba de arlomo)的植物化学成分及其作为输液的一般消费。产生了水提取物和乙醇提取物,同时对所获得的提取物中的植物化合物含量进行了量化。结果表明,乙醇提取物的酚类化合物和单宁含量最高,其中雪松的含量最高(831.04 mg L -1) 和 Cancerina (864.80 mg L -1 )。还测定了抗氧化活性,观察到显着差异 ( p< 0.05)。具有最高抗氧化能力的提取物是乙醇提取物,范围从 250 到 907 μMET mL -1,而水提取物范围从 112 到 390 μMET mL -1. 通过对水提取物进行高效液相色谱表征鉴定的化合物突出了绿原酸>肉桂酸>槲皮素的存在。在乙醇提取物中,突出了绿原酸>肉桂酸>槲皮素>没食子酸>阿魏酸>香豆酸的存在。生物活性化合物、提取物类型和抗氧化活性之间的相关性表明这些植物化学化合物对乙醇溶剂具有显着的亲和力。结果表明,这些植物是抗氧化酚类物质的良好来源,可用作功能性饮料。然而,需要更多的研究来证实它们的有益作用。
