Plectranthus ornatus is a medicinal and aromatic plant used in traditional and alternative medicine. In this study, leaves of P. ornatus were collected in two cities of the state of Pará, “Quatipuru” and “Barcarena”, and were used with the objective of analyzing, through morphoanatomical data and histochemical and phytochemical studies of essential oil, the samples present structural differences and differences in their chemical composition. Anatomical and histochemical analyses were performed by transverse, using longitudinal sections of 8 μm to 10 μm to perform epidermal dissociation, diaphonization, and tests to identify classes of secondary metabolites. The essential oils were isolated by hydrodistillation, and the identification of the chemical composition was performed by gas chromatography coupled with mass spectrometry. The anatomical study shows that there is no difference between specimens collected in different locations, and stellate trichomes were identified. The histochemical study detected total lipids and acids, terpenes, polysaccharides, phenolic compounds, tannins, alkaloids, and calcium oxalate. The low essential oil yield may be related to the low density of secretory cells (glandular trichomes), the unidentified compounds in the highest concentration in the essential oil were in relation to the chemical composition of the essential oils, and the major compounds were α-pinene, sabinene, (E)-caryophyllene, caryophyllene oxide, and oct-1-en-3-ol. The results provide new information about the anatomy and histochemistry of P. ornatus.

“…The terpene identification is more effective when the reaction happens (positive result), as seen in this study and also in previous works with P. amboinicus, Mentha x villosa Huds [ 18 , 32 ]. Genus Ocimum terpenes can also be found in the stem [ 33 ].…”

“…Principalmente devido que algumas plantas retêm princípios ativos com efeitos desconhecidos ou até tóxicos (como por exemplo os compostos cinogenicos). Por esse motivo, a fitoterapia é um tratamento caracterizado pelo uso de plantas medicinais que utiliza substâncias ativas na forma de fitocomplexos, onde um marcador químico desempenhará o papel de controle de qualidade, dessa forma garantindo integridade química e farmacológica do material (Rocha et al, 2020).…”

Devido as suas propriedades terapêuticas, as plantas aromáticas são bastante utilizadas pela população para fins medicinais, aromatizantes, condimentares e para estudos científicos a respeito das ações farmacológicas: anti-inflamatória, antiespasmódica, antioxidantes, antissépticas, antimicrobianas, calmantes, carminativa, entre outras. Por isso, o objetivo vem com o intuito de facilitar a produção das plantas aromáticas para auxiliar a população e os profissionais da saúde a buscar conhecimentos sobre os efeitos farmacológicos e fisiológicos dos compostos bioativos de cada planta em prol da saúde humana, através da fitoterapia. O trabalho foi embasado em pesquisas de artigos publicados no período de 2013 a 2021 de acordo com a revisão bibliográfica nas plataformas cientificas: SciELO e PUBMED, com respectivas seleções e leituras dos artigos no mês de julho a setembro. No total foram obtidos 30 artigos, nos quais foram excluídos aqueles que continham repetições e não apresentavam contexto compatível com o tema, restando apenas 21 artigos selecionados. Com base, na revisão bibliográfica foram selecionadas 10 espécies de plantas aromáticas (Alecrim; Orégano; Boldo brasileiro; Arruda; Hortelã comum; Erva-cidreira; Capim-limão; Alfavaca; Sálvia; Alfazema), com suas respectivas informações: nome cientifico, nome popular, parte usada da planta, propriedade farmacológica, indicação terapêutica. O estudo identificou dentro da fitoterapia e da medicinal tradicional, diferentes abordagens e costumes acerca do uso correto no manejo de plantas medicinais. Além de contribuir para difundir o conhecimento a cerca dessa classe de plantas (aromáticas), o presente estudo fornece ferramentas com base na leitura acerca da forma do uso para o preparo mais eficiente dessas espécies aqui revisadas.

The aim of this study was to evaluate the influence of the use of the biostimulant Stimulate® on the biomass production of green basil. A randomized block design was used, in a 5x2 factorial scheme with six replications, analyzing different concentrations (0, 5, 10, 15 and 20 mL L-1 of water) and application method (single application and split into 2 times). Harvesting was performed 60 days after transplanting. The variables evaluated were plant height, counting of the number of secondary and tertiary shoots, root length and volume, fresh and dry matter mass, leaf area and essential oil yield. There was no interaction between the concentrations of Stimulate® and the application method. However, there was an increase in all variables analyzed with the concentration of 20 mL per L of water. The application of the biostimulant Stimulate® had an effect on biomass production, plant height, canopy diameter, secondary and tertiary shoots, length and volume of the root system, fresh matter mass of the aerial part and root. Increases in these variables were also observed in response to increased concentrations of Stimulate® and accumulation of green basil essential oil.
