Plantas medicinales de Oaxaca, México: Etnobotánica y actividad antibacteriana
Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants, 2020
Santiago Quiotepec, one of the oldest communities of the Tehuacan-Cuicatlan Valley (Mexico), has a great tradition using medicinal plants. The aim of this study was to make an inventory of the medicinal species used by the inhabitants of Santiago Quiotepec and evaluate the antibacterial activity. An ethnobotanical study of medicinal plants was carried out, 60 informants mentioned that 66 species of plants are being used in the treatment of different diseases. Fifteen species were selected to evaluate the antibacterial activity in possible bacterial originated diseases treatment. The lowest values were presented in the hexane extract of Plumbago pulchella, with a MIC of 0.25 mg/mL over Staphylococcus aureus and S. epidermidis as well as the hexanic extract of Echinopterys eglandulosa showed a MIC of 0.25 mg/mL over Pseudomona aeruginosa.
Antibacterial activities of medicinal plants used in Mexican traditional medicine
Ethnopharmacological relevance: We provide an extensive summary of the in vitro antibacterial properties of medicinal plants popularly used in Mexico to treat infections, and we discuss the ethnomedical information that has been published for these species. Materials and methods: We carried out a bibliographic investigation by analyzing local and international peer-reviewed papers selected by consulting internationally accepted scientific databases from 1995 to 2014. We provide specific information about the evaluated plant parts, the type of extracts, the tested bacterial strains, and the inhibitory concentrations for each one of the species. We recorded the eth-nomedical information for the active species, as well as their popular names and local distribution. Information about the plant compounds that has been identified is included in the manuscript. This review also incorporates an extensive summary of the available toxicological reports on the recorded species, as well as the worldwide registries of plant patents used for treating bacterial infections. In addition, we provide a list with the top plant species with antibacterial activities in this review Results: We documented the in vitro antibacterial activities of 343 plant species pertaining to 92 botanical families against 72 bacterial species, focusing particularly on Staphylococcus aureus, Mycobacterium tuberculosis, Escherichia coli and Pseudomonas aeruginosa. The plant families Asteraceae, Fabaceae, La-miaceae and Euphorbiaceae included the largest number of active species. Information related to popular uses reveals that the majority of the plants, in addition to treating infections, are used to treat other conditions. The distribution of Mexican plants extended from those that were reported to grow in just one state to those that grow in all 32 Mexican states. From 75 plant species, 225 compounds were identified. Out of the total plant species, only 140 (40.57%) had at least one report about their toxic effects. From 1994 to July 2014 a total of 11,836 worldwide antibacterial patents prepared from different sources were recorded; only 36 antibacterial patents from plants were registered over the same time period. We offered some insights on the most important findings regarding the antibacterial effects, current state of the art, and research perspectives of top plant species with antibacterial activities in vitro. Conclusions: Studies of the antibacterial in vitro activity of medicinal plants popularly used in Mexico to treat infections indicate that both the selection of plant material and the investigation methodologies vary. Standardized experimental procedures as well as in vivo pharmacokinetic studies to document the effectiveness of plant extracts and compounds are necessary. This review presents extensive information about the medicinal plants possessing antibacterial activity that has been scientifically studied and are popularly used in Mexico. We anticipate that this review will be of use for future studies because it constitutes a valuable information tool for selecting the most significant plants and their potential antibacterial properties.
ANTIMICROBIAL ACTIVITY OF NINE MEDICINAL PLANTS FROM VERACRUZ, MEXICO
The medicinal plants are an alternative source to the treatment of primary health care problems. An ethnobotanical study performed on Tlalchy, Ixhuacán de los Reyes, Veracruz, México, allowed the selection of nine plant species involved in infectious diseases treatments. Antimicrobial activities of ethanolic crude extracts were tested on fifteen bacterial and yeast clinical isolates. Every extract showed a level of inhibition against almost all the microorganisms assayed. According to the Clinical and Laboratory Standards Institute norms, representative results emerged over three species: T. diversifolia, C. nitidula y L. racemosa, therefore, Minimal Inhibitory Concentration values were determined on these species. The data suggest that using medicinal plants of Tlalchy is convenient, for this reason, we put forward further investigation on several species.

Twelve methanolic plant extracts from botanical species used in traditional medicine in Morelos, M6xico to cure infectious diseases have been subjected to a screening study to detect potential antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. The antimicrobial activity of the products was evaluated using colonies growing in solid medium, establishing the minimal concentration required to inhibit their in vitro growth (MIC). The results showed that extracts from Eucalyptus globolus Labill, Punica granatum L., Artemisia mexicana Willd., and Bocconia arborea Watt. possess strong in vitro antimicrobial activity against the tested microorganisms.
Antimicrobial activity of plants used in traditional medicine of San Juan province, Argentine
Journal of Ethnopharmacology, 2001
Eighteen extracts from Acaena magellanica, Baccharis grisebachii, Ephedra breana, Oxalis erythrorhiza, Pachylaena atriplicifolia and Satureja par6ifolia were assessed for antimicrobial activity against bacteria and fungi with the agar dilution method. The hexane (H) and dichloromethane (DCM) extracts of B. grisebachii and O. erythrorhiza showed the broadest spectrum of action against fungi, inhibiting all of the tested dermatophytes with MICs ranging from 5 25 to 51000 mg/ml. Trichophyton rubrum was the most susceptible species and Cryptococcus neoformans was inhibited only by the DCM extract of B. grisebachii with MIC of 600 mg/ml. Regarding the antibacterial activity, H and DCM extracts of B. grisebachii as well as the DCM of O. erythrorhiza, were active on methicillin-resistant and methicillin-sensitive Staphylococcus aureus with MIC from 5 125 to 5 500 mg/ml. The DCM extract of B. grisebacchii was more active against methicillin-resistant than methicillin-sensitive strains.

Antibacterial properties of aqueous and methanolic extracts of 26 medicinal plants used in Mexico to treat gastrointestinal disorders were tested against eight different species of enteropathogens: two Escherichia coli species; two Shigella sonnei species; two Shigella flexneri species; and two Salmonella sp. species. The results showed that all crude extracts exhibited antibacterial activity, at least against one of the microorganisms tested, at concentrations of 8 mg/mL or lower. The extracts from Caesalpinia pulcherria, Chiranthodendron pentadactylon, Cocos nucifera, Geranium mexicanum (aerial parts and roots), Hippocratea excelsa, and Punica granatum possessed strong antibacterial activity against most of the pathogens tested. In general, methanolic extracts were more active than aqueous extracts. Their activity was higher than chloramphenicol but did not exceed that of trimethoprim. Shigella sonnei species showed the highest susceptibility to both extracts. This is the first evaluation of these plants against bacterial pathogen isolates, which cause diarrhea and dysentery in Mexican population.

Indian Journal of Traditional Knowledge, 2017
The aim of this study was to evaluate antimicrobial potential of methanolic plant extracts: Carya illinoensis (Wangenh.) K. Koch, Selaginella lepidophylla (Hook. and Grev.) Spring, Euphorbia antisyphilitica Zucc., and Jatropha dioica Sesse. Plant samples were collected from northern Mexico and the extracts were tested against reference bacteria (RS): Staphylococcus aureus (BAA44) and Klebsiella pneumoniae (9180) and clinical isolated bacteria (CB): Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Escherichia coli. Antimicrobial activity was performed with Steers Replicator, the LD 50 was evaluated with Artemia salina bioassay, and a phytochemical screening was done with colorimetric tests. The extracts showed a minimum inhibitory concentration of 500 µg/mL and LD 50 of 1000 µg/mL. The phytochemical tests were positive for flavonoids, lactones, quinones, triterpenes and sterols. C. illinoensis, S. lepidophillla and J. dioica had high correlations (≥ 0.969) to inhibit the growth of S. aureus (RS and CB), K. pneumoniae (RS) and K. pneumoniae (CB) (p = 0.080, 0.076, 0.016 and 0.029, respectively). The results will contribute to the knowledge of plants used in Mexican traditional medicine.
