Using ethnobotanical techniques, the medicinal flora used by the inhabitants of San Rafael Coxcatlán, Puebla was determined. During the field work, two types of interviews were applied (free listing and semi-structured) to 60 informants, who supplied consistent information concerning the use of 46 species of medicinal plants. Further analysis showed 13 categories of different medicinal use. An informant consensus factor was calculated and 16 species were selected due to their utilization in the treatment of diseases of possible bacterial origin. Of these 16 plants, sequential extractions were made with hexane, ethyl acetate and methanol. The obtained extracts were used to assess their antibacterial activity against 14 bacterial strains; 75% of the plants presented antibacterial activity. The medicinal species Jatropha neopauciflora Pax (Euphorbiaceae) and Juliania adstringens (Schldl.) Schldl. (Julianiaceae) were those that showed the biggest activity. Moreover, these species also had the highest informant consensus factor values.
运用民族植物学技术，确定了普埃布拉州圣拉斐尔科斯卡特兰居民所使用的药用植物群。在实地考察期间，对60名信息提供者进行了两种类型的访谈（自由列举和半结构化访谈），他们提供了关于46种药用植物使用情况的一致信息。进一步分析显示有13种不同的药用类别。计算了信息提供者共识因子，并挑选出16种因其用于治疗可能由细菌引起的疾病的植物。对这16种植物依次用己烷、乙酸乙酯和甲醇进行提取。所得提取物用于评估其对14种细菌菌株的抗菌活性；75%的植物具有抗菌活性。药用植物新少花麻风树（大戟科）和收敛朱利桉（朱丽桉科）表现出最大的活性。此外，这些物种的信息提供者共识因子值也最高。
