“…We just found precious slight spathulenol (0.7%) which accounts for 9.25-22.44% in H. suaveolens of Brazilian Cerrado (Azevedo et al, 2002). We could not find any traces of bicyclogermacrene and germacrene B described by Azevedo et al (2001), Oliveira et al (2005) and McNeil et al (2011). Thirty-three components were identified in the essential oil of H. rhomboidea accounting for 87.25% and the main compounds were (À)-isocaryophyllene (7.48%), (À)-b-cadinene (7.11%) and butylated hydroxytoluene (29.90%).…”

“…The Hyptis genus is a member of the Lamiaceae family and includes about 775 species (McNeil et al, 2011), which are mainly grown in the tropical to subtropical area of American and the West Indies. Several flourishes around the tropics in the world (Azevedo et al, 2001(Azevedo et al, , 2002Luz et al, 1984;Oliveira et al, 2005). There are four species, Hyptis suaveolens, Hyptis rhomboidea, Hyptis brevipes and Hyptis.…”

Context: Hyptis suaveolens (Linn.) Poit., Hyptis rhomboidea Mart. et Gal., and Hyptis brevipes Poit., are three species of Hyptis Jacq. (Lamiaceae). Hyptis suaveolens is used for the treatment of fever, headache, gastrointestinal bloating and rheumatism in the traditional folk medicine; Hyptis rhomboidea for hepatitis, ulcer and swollen poison; and Hyptis brevipes for asthma and malaria. Objective: To characterize chemical compositions of the oils from three Hyptis species and evaluate their potential antimicrobial, radical scavenging activities and toxicities against brine shrimp. Materials and methods: The oils were obtained by hydrodistillation, and their chemical compositions were investigated by gas chromatography-mass spectrometry (GC-MS). Minimum inhibitory concentrations (MICs) were determined using the tube double-dilution technique. The antioxidant activities were investigated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and toxicities by the brine shrimp bioassay. Results: Forty-seven, 33 and 28 constituents of oils isolated, respectively, from H. suaveolens, H. rhomboidea and H. brevipes were identified. Among the essential oils, the strongest antioxidant activity was exhibited by H. brevipes with an SC 50 value of 2.019 AE 0.25 mg mL À1. The H. brevipes oil exhibited the strongest antimicrobial activity (3.125-6.25 mg mL À1) on pathogens employed in the assay. They all showed significant toxicities with median lethal concentration (LC 50 ) values of 62.2 AE 3.07 mg mL À1, 65.9 AE 6.55 mg mL À1 and 60.8 AE 9.04 mg mL À1, respectively. Discussion and conclusions: The three Hyptis species oils possess strong antimicrobial activities and toxicities. Hyptis rhomboidea and H. brevipes showed considerable antioxidant activity compared to the positive control.

“…However, their practical application is reduced by differences in composition of essential oils between plant species and populations and phase of plant growth (Zygadlo and Juliani, 2003;Oliveira et al, 2005;Muñoz-Bertomeu et al, 2007).…”

We investigated the effects of five allyl esters, two aromatic (allyl cinnamate and allyl 2-furoate) and three aliphatic (allyl hexanoate, allyl heptanoate, and allyl octanoate) in established insect cell lines derived from different species and tissues. We studied embryonic cells of the fruit fly Drosophila melanogaster (S2) (Diptera) and the beet armyworm Spodoptera exigua (Se4) (Lepidoptera), fat body cells of the Colorado potato beetle Leptinotarsa decemlineata (CPB) (Coleoptera), ovarian cells of the silkmoth Bombyx mori (Bm5), and midgut cells of the spruce budworm Choristoneura fumiferana (CF203) (Lepidoptera). Cytotoxicity was determined with use of MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] and trypan blue. In addition, we tested the entomotoxic action of allyl cinnamate against the cotton leafworm Spodoptera littoralis .The median (50%) cytotoxic concentrations (EC₅₀s) of the five allyl esters in the MTT bioassays ranged between 0.25 and 27 mM with significant differences among allyl esters (P = 0.0012), cell lines (P < 0.0001), and the allyl ester-cell line interaction (P < 0.0001). Allyl cinnamate was the most active product, and CF203 the most sensitive cell line. In the trypan blue bioassays, cytotoxicity was produced rapidly and followed the same trend observed in the MTT bioassay. In first instars of S. littoralis, allyl cinnamate killed all larvae at 0.25% in the diet after 1 day, while this happened in third instars after 5 days. The LC₅₀ in first instars was 0.08%. In addition, larval weight gain was reduced (P < 0.05) after 1 day of feeding on diet with 0.05%. In conclusion, the data provide evidence of the significant but differential cytotoxicity among allyl esters in insect cells of different species and tissues. Midgut cells show high sensitivity, indicating the insect midgut as a primary target tissue. Allyl cinnamate caused rapid toxic effects in S. littoralis larvae at low concentrations, suggesting further potential for use in pest control.

“…Além do estudo medicinal desta espécie, outros estudos são registrados na literatura como, por exemplo, influencia do ambiente na composição química (Grassi et al, 2005, Oliveira et al, 2005, influencia da adubação mineral e orgânica (Martins et al, 2006;Maia et al 2008) e sobre aspectos reprodutivos (Lopes & Jardim, 2008;Martins & Polo, 2009), com estudos de propagação tanto pela via sexual (Wulff, 1973;Oliveira Junior et al, 2007;Maia et al, 2008;), quanto por via vegetativa (estaquia) (Maia et al, 2008;Silva et al 2011), mas há aspectos nos estudos no que concerne sobre a propagação vegetativa que necessita ser investigados, no que diz respeito, principalmente, quanto a composição do substrato na produção de mudas desta espécie, por ser um fator relevante no enraizamento de estacas (Hartmann et al, 2002).…”

Efeito da composição de substratos no enraizamento de estacas de Hyptis suaveolens (L.) RESUMOHyptis suaveolens (L.) Poit. é uma planta medicinal de alto potencial terapêutico, popularmente conhecida por bamburral. O objetivo do presente trabalho foi verificar o efeito dos diferentes tipos de composição de substratos para enraizamento de estacas medianas de Hyptis suaveolens. O estudo foi realizado em casa de vegetação no Setor Solos do Departamento de Ciências Ambientais, da Universidade Federal Rural do Semi-Árido (UFERSA) no mês de maio de 2010. Os tratamentos constaram dos seguintes substratos: arisco (T1), areia (T2), mistura de areia, arisco e esterco bovino (1:1:1) (T3), mistura de esterco e areia (2:1) (T4) e mistura de arisco, areia e húmus (1:1:1) (T5). O delineamento experimental foi inteiramente casualizado com cinco tratamentos e quatro repetições, sendo 10 estacas por parcela. As características avaliadas foram porcentagem de enraizamento, comprimento da maior raiz, diâmetro da estaca, massa seca da parte aérea e de raiz. Os substratos areia, arisco e a combinação da mistura entre eles com o esterco bovino destacaram-se dos demais substratos na percentagem de enraizamento. Recomenda-se para a produção de mudas de bamburral a combinação de mistura de substratos areia, arisco e esterco bovino. Palavras-chave: estaquia, planta medicinal, planta silvestre Effect of substrate composition on rooting of cuttings of Hyptis suaveolens ABSTRACTHyptis suaveolens (L.) Poit., is considered to be a plant of high therapeutic potential. The objective of this study was to evaluate the effect of the different composition of substrates for rooting medians of Hyptis suaveolens. The study was conducted in greenhouse Sector Soil Environmental Sciences Department, Federal Rural University of the Semi-Arid (UFERSA) in May 2010. The treatments were the following substrates: arisco soil (T1), sand (T2), mixture of manure and sand (2:1) (T3), a mixture of sand, arisco soil and manure (1:1:1) (T4), and mixture of arisco soil, sand and humus (1:1:1) (T5). The experimental design was a completely randomized design with five treatments and four replications and 10 cuttings per plot. The evaluated characteristics were the rooting percentage, longest root length, diameter of the cuttings, dry mass of shoot and root. Substrates sand, arisco soil, and the combination of their mixture with cattle manure, stood out from other substrates in the percentage of rooting. Therefore, a combination of mixed sand, arisco soli and cattle manure is recommended for the production of seedlings of bamburral.
