“…Originally from South America, A. triplinervis (synonym: Eupatorium triplinerves) can be found in Brazil, Ecuador, Peru, Puerto Rico and Guyana, besides being adapted in other countries like India and Vietnam [7]. The species is found in Brazil in two morphotypes: Japana-Branca (morphotype A) and Japana-roxa (morphotype B) [8].…”

Ayapana triplinervis is a plant species used in traditional medicine and in mystical-religious rituals by traditional communities in the Amazon. The aim of this study are to develop a nano-emulsion containing essential oil from A. triplinervis morphotypes, to evaluate larvicidal activity against Aedes aegypti and acute oral toxicity in Swiss albino mice (Mus musculus). The essential oils were extracted by steam dragging, identified by gas chromatography coupled to mass spectrometry, and nano-emulsions were prepared using the low energy method. Phytochemical analyses indicated the major compounds, expressed as area percentage, β-Caryophyllene (45.93%) and Thymohydroquinone Dimethyl Ether (32.93%) in morphotype A; and Thymohydroquinone Dimethyl Ether (84.53%) was found in morphotype B. Morphotype A essential oil nano-emulsion showed a particle size of 101.400 ± 0.971 nm (polydispersity index = 0.124 ± 0.009 and zeta potential = -19.300 ± 0.787 mV). Morphotype B essential oil nano-emulsion had a particle size of 104.567 ± 0.416 nm (polydispersity index = 0.168 ± 0.016 and zeta potential = -27.700 ± 1.307 mV). Histomorphological analyses showed the presence of inflammatory cells in the liver of animals treated with morphotype A essential oil nano-emulsion (MAEON) and morphotype B essential oil nano-emulsion (MBEON). Congestion and the presence of transudate with leukocyte infiltration in the lung of animals treated with MAEON were observed. The nano-emulsions containing essential oils of A. triplinervis morphotypes showed an effective nanobiotechnological product in the chemical control of A. aegypti larvae with minimal toxicological action for non-target mammals.

“…At the midrib, immediately under the epidermal cells, two to four layers of angular collenchyma cells are observed, a common feature to other members of the family Asteraceae (Metcalfe and Chalk, 1972): Ayapana triplinervia (Nery et al, 2014) and Mikania laevigata (Budel et al, 2009). The fundamental parenchyma shows several layers of cells with different sizes.…”

Vernonia ferruginea Less. is a perennial shrub species, present in several regions of Brazil, especially in the savanna. It is popularly used as a phytotherapic. This fact justifies the need to anatomically characterize the plant for its accurate identification and to conduct histochemical studies with the aim of identifying the chemical nature of its cellular constituents. The species-specific data will contribute significantly to pharmaceutical quality control and also provide information about the sites of specific chemical compounds. Samples of V. ferruginea vegetative organs were collected and submitted to the usual plant anatomy and histochemical techniques. The leaves are anfihipoestomática with anomocytic stomata; have tector and glandular trichomes that store essential oils. The stem has collateral-type vascular bundles arranged in a eustele structure; it also has glandular and tector trichomes. The root has brachysclereids, endoderm with various chemical compounds and vascular bundles having axial elements and rays. Few differences were found in the structure of vegetative organs in relation to other species of the genus, confirming the importance of the details shown.

“…Consoante Nery et al (2014), a espécie A. triplinervis é uma erva ocorrente na região amazônica, sendo denominada popularmente como "Erva de cobra" ou "Japana", tendo suas variações de "Japana branca" e "Japana roxa". Estudos etnobotânicos desta espécie consolidaram seu alto uso para tratamento de febre, feridas na boca, problemas gastrointestinais, malária e verminoses.…”

Este trabalho teve como objetivo caracterizar espécimes de japana (Ayapana triplinervis) do horto medicinal da Universidade Federal Rural da Amazônia - Campus Belém em diferentes tipos de testes histoquímicos. Algumas plantas possuem uma grande quantidade de variedades, ecotipos e quimiotipos, dificultando a identificação da mesma. As fotomicrografias em microscopia fotônica foram obtidas a partir de lâminas histológicas dos órgãos vegetativos da raiz, caule e folha, confeccionadas a mão livre, seguindo as técnicas usuais da anatomia vegetal. Os testes histoquímicos foram feitos através da utilização dos reagentes Sudan Black B (Pearse), Lugol (Johansen et al) e Azul de Toluidina (O’ Brien et al), para a detecção dos compostos de lipídios, amido e polissacarídeos ácidos, respectivamente, seguindo a metodologia citada nas literaturas destes autores.
