Essential oil composition of leaf and fine stem of Aniba canelilla (Kunth) Mez from Manaus, Brazil Acta Amazonica
Lima,Maria da Paz; Silva,Tatiana Maria D.; Silva,João Domingos da; Zoghbi,Maria das Graças B.; Andrade,Eloisa Helena A..
The essential oil of the leaves and fine stems of Aniba canelilla (Kunth) Mez collected in the city of Manaus, AM, Brazil, were obtained by hydrodistillation and analyzed by GC/MS. Forty-two components were identified, of which 1-nitro-2-phenylethane, as expected, was the major (71.2%-68.2%).

Seasonal variation in the essential oil of Pilocarpus microphyllus Stapf. Anais da ABC (AABC)
TAVEIRA,FRANCISCA S. N.; ANDRADE,ELOISA H. A.; LIMA,WATERLOO N.; MAIA,JOSÉ G. S..
The essential oils of the leaves and fine stems of Pilocarpus microphyllus, collected on iron mineralized soil of the Serra de Carajás, Southeast of Pará State, Brazil, during the rainy and dry seasons, were obtained by hydrodistillation and analyzed by GC-MS. The main identified compounds were 2-tridecanone, beta-caryophyllene, 2-pentadecanone, caryophyllene oxide and germacrene D. Their percentage contents varied with the season, the greater values having been detected mainly in the rainy season. For 2-tridecanone and beta-caryophyllene the higher values were observed in the fine stem oils for the former, and in the leaf oils for the latter. For 2-pentadecanone, caryophyllene oxide and germacrene D they were also in the leaf oils. In general, the leaf...

Leishmanicidal activity of carvacrol-rich essential oil from Lippia sidoides Cham Biol. Res.
Farias-Junior,Paulo A; Rios,Marcos C; Moura,Tauanny A; Almeida,Roque P; Alves,Pericles B; Blank,Arie F; Fernandes,Roberta P M; Scher,Ricardo.
Leishamaniasis is a disease that affects more than 2 million people worldwide, whose causative agent is Leishmania spp. The current therapy for leishmaniasis is far from satisfactory. All available drugs, including pentavalent antimony, require parenteral administration and are potentially toxic. Moreover, an increase in clinical resistance to these drugs has been reported. In this scenario, plant essential oils used traditionally in folk medicine are emerging as alternative sources for chemotherapeutic compounds. In this study, in vitro leishmanicidal effects of a thymol- and a carvacrol-rich essential oil from leaves of Lippia sidoides Cham. were investigated. The essential oils were extracted and their constituents were characterized by gas...

Essential oil yield and composition of Lamiaceae species growing in southern Brazil BABT
Agostini,Fabiana; Santos,Ana Cristina Atti dos; Rossato,Marcelo; Pansera,Márcia Regina; Santos,Paula Luciana dos; Serafini,Luciana Atti; Molon,Rosângela; Moyna,Patrick.
The Lamiaceae family has been described to be rich in essential oil. The aim of the present work was to identify the native species of Rio Grande do Sul with potential use as the aromatic plants. Seven species of the family were collected in the different localities of the state. The essential oils were obtained by 1h hydrodistillation in a Clevenger apparatus. The constituents were identified by comparing their GC Kovats retention indices (RI), determined with reference to a homologous series of n-alkanes and by comparing their mass spectral fragmentation patterns with literature data. Cunila incisa and Mentha aquatica resulted in the higher esssential oil yields (1.94% v/w and 0.93% v/w, respectively. The composition of M. aquatica was 80% methone, with...

Comparison of volatile and polyphenolic compounds in Brazilian green propolis and its botanical origin Baccharis dracunculifolia Ciênc. Tecnol. Aliment.
Maróstica Junior,Mário Roberto; Daugsch,Andreas; Moraes,Cleber Silveira; Queiroga,Carmen Lucia; Pastore,Gláucia Maria; Parki,Yong Kun.
Ethanolic extracts and essential oils from Green Propolis from southeastern Brazil and leaf buds from its botanical origin Baccharis dracunculifolia were analyzed by Reversed Phase High Performance Liquid Chromatography (RP-HPLC), Reversed Phase High Performance Thin Layer Chromatography (RP-HPTLC) and Gas Chromatography - Mass Spectrometry (GC-MS). The essential oils were obtained by hydro-distillation. Both ethanolic extracts and essential oils showed similar chromatographic profiles. Thirteen flavonoids were identified by RP-HPLC and RP-HPTLC analyses in both samples. Twenty-three volatile compounds were identified by GC-MS analyses. Seventeen were present in both essential oils. The major flavonoid compound in both extracts was artepillin C. The major...
