© 2018 IEEE.Clinopodium mexicanum known as poleo is a native plant with medicinal use. It is used as a tranquilizer and analgesic in traditional Mexican medicine. The therapeutic effect of the plant has been related to the flavonoids present in the aqueous extract. This work focuses on the determination of edaphoclimatic conditions and concentration of total flavonoids of three poleo populations in the semi-desert of Querétaro. The populations sampled were at north of Bernal (Municipio Ezequiel Montes)), Sombrerete (Mpio. Cadereyta de Montes) and Maguey Verde (Mpio. Peñamiller). The spectrophotometric assay for the quantitative determination of the flavonoid content was carried out. An analysis of the physicochemical properties of the soil was carried out. The meteorological data of temperature, relative humidity and precipitation were extracted from the climate data base of the Secretaria de Desarrollo Agropecuario (SEDEA). The populations sampled were characterized by presenting soils of medium texture, low humidity retention and moderately alkaline pH. Significant differences were found in the total flavonoid content between the populations. The concentration of total flavonoids in Maguey Verde was significantly lower than those obtained in northeast of Bernal and Sombrerete.
