Abstract Mikania glomerata and Mikania laevigata are medicinal plants popularly used in Brazil for colds and asthma. Although several studies report differences in their composition, they are frequently used indistinctly, which may be due to misidentification of the species or the plant part used. Herein, the chemical, anatomical, and morphological profiles of both species were evaluated, seeking to differentiate them. Due to the pattern of secondary metabolites found in M. glomerata and M. laevigata, the chemical profile of the leaves was the characteristic that best differentiated the two species. Coumarin was present in all the leaf samples of M. laevigata but absent or in low concentration in leaf samples of M. glomerata. The stems presented coumarin in both species, albeit in different concentrations. The quantification of chlorogenic and dicaffeoylquinic acids was crucial for the separation of the two species, as higher concentrations are found in M. glomerata. The anatomic structure of the leaves, stem, and petioles of both species was conserved, even when exposed to different environments, but presented only subtle differences between species. The morphology of the leaves presented different characteristics for each species but altered when exposed to shade. Therefore, the chemical analysis together with the morphological characteristics of plants grown in full sunlight may be used for the correct identification of these species.

Abstract Background: Small ruminant health problems still represent a major constraint in Benin. Thus, to treat goats and sheep diseases, breeders use medicinal plants. However, little scientific work has been done on the traditional knowledge of these plants.The specific objectives of the current study were (i) to document the traditional knowledge regarding the disease groups treated and the medicinalplants used in the health and zootechnical management of small ruminants in Benin and (ii) to assess the effect of sex, ethnicity, agroecological zone and herd sizeassociatedwith them. Methods: To achieve these objectives, an ethnoveterinary survey was conducted in different agroecological zones from September 2018 to February 2019. A semi-structured questionnaire was administered to 506 breeders and farmers and took into account the identity of the respondents, the plants used to treat the ailmentsfor improving the productivity of sheep and goats, the parts used and the method of preparation of the recipes. The data were analyzed through the calculation the Relative Frequency of Citation (RFC), Fidelity Level (FL), and Consensus Factor of the Informant (CFI). Descriptive statistics and multivariate analyses were applied to our data using the software R and Minitab. The symptoms recordedfrom the respondents were categorized into 10 disorder groups using the second version of the International Classification of Primary Care (ICPC). Results: Ten (10) categories of disorders were treated by the people surveyed. These are mainly disorders of the digestive system (D) (49.34%) and disorders related to pregnancy and parturition (W) (20.15%). A total of 101 species medicinal plantsbelonging to 42 families and 90 genera were recorded. The most represented families are Leguminosae (21.57%) and Euphorbiaceae (6.86%). The most cited speciesare Zanthoxylumzanthoxyloides (Lam.) Watermann, Khayasenegalensis (Desr.) A. Juss, Strigahermonthica (DeliIe) Benth. and Adansoniadigitata L. Sex, ethnicity, agroecological zone and herd size are the socioeconomic and environmental factors that influence the level of ethnoveterinary knowledge. Conclusions: Results showedthe high diversity of medicinal species used to treat small ruminant’sdiseasesin Benin. Chemical and biological analyzes are needed to test the effectiveness of the main inventoried plants. Keywords : Ethnoveterinary, sheep, goats, Benin.
