“…Há relatos de variação na composição química de óleos voláteis de diferentes espécies vegetais em função de variações sazonais (Chericoni et al, 2004;Asghari et al, 2002;Taveira et al, 2003;Blank et al, 2007), de latitude (Azevedo et al, 2002) e de condições climáticas (Lago et al, 2003), além de variação relacionada a injúria mecânica (Zabaras & Wyllie, 2001). Entretanto, uma determinada espécie pode apresentar quimiotipos ou tipos baseados em diferenças genéticas (Thompson et al, 2003) e, conseqüentemente, apresentar polimorfi smo químico.…”

RESUMO:Duguetia furfuracea, Annonaceae, uma invasora de pastagens, é também usada na medicina tradicional em diversos estados no Brasil. Devido à signifi cante diferença de odor entre dois grupos de indivíduos desta planta em um remanescente de cerrado em Campo Grande, Mato Grosso do Sul, seis amostras foram selecionadas de acordo com a intensidade de odor em suas folhas: In-01, In-03 e In-05: odor pronunciado (Perfi l A); In-02, In-04 e In-06: odor fraco ou ausência de odor (Perfi l B). As folhas foram coletadas e submetidas a hidrodestilação para obtenção dos óleos essenciais, os quais foram analisados por CG/EM. Uma boa compatibilidade foi encontrada entre os resultados obtidos por CG/EM e a análise olfativa adotada para as amostras: espécimes odor pronunciado apresentaram uma alta porcentagem de monoterpenos e alguns sesquiterpenos: In-01 ( -felandreno, 42,2%; mirceno, 6,8%; -felandreno, 4,6%); In-03 (terpin-4-ol, 21,6%; sabineno, 17,3%; p-cimeno, 5,6%); In-05 (sabineno, 25,1%; terpin-4-ol, 16,2%; pcimeno, 8,3%). Apenas sesquiterpenos foram encontrados nos espécimes que apresentaram odor fraco ou ausência do mesmo (com constituinte majoritário biciclogermacreno: 21,4%, 24,0%, and 29,1%, respectivamente, para os In-02, In-04 e In-06).Unitermos: Duguetia furfuracea, Annonaceae, óleo volátil.ABSTRACT: "Chemical variability of the essential oil of the leaves from six individuals of Duguetia furfuracea (Annonaceae)". Duguetia furfuracea, Annonaceae, a pasture weed, is also used in folk medicine in several Brazilian states. Because of the signifi cant difference in odor between two groups of this plant in a remnant patch of savanna in Campo Grande county, Mato Grosso do Sul, six samples were selected according to the odor intensity in the leaves (In-01, In-03, and In-05: pronounced odor; In-02, In-04, and In-06: weak odor or its absence). The leaves were collected and subjected to steam distillation for extraction of essential oils, which were analyzed by GC-MS. A good agreement was found between CG/MS results and olfactory evaluation of the samples: specimens exhibiting leaf scent had a high percentage of monoterpenes and some sesquiterpenes, as follows: In-01 ( -phellandrene, 42.2%; myrcene, 6.8%; -phellandrene, 4.6%); In-03 (terpin-4-ol, 21.6%; sabinene, 17.3%; p-cymene, 5.6%); 25.1%; 16.2%; 8.3%). Only sesquiterpenes were found in the specimens having weakly scented or scentless leaves (main constituent bicyclogermacrene: 21.4%, 24.0%, and 29.1%, respectively, for In-02, In-04 and In-06).

“…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.
