1. In vivo and in vitro Volatile Constituents of the Flowers of Xylopia aromatica by HS-SPME/GC-MS
Xylopia aromatica (Lam.) Mart. (Annonaceae) is a typical species from the Brazilian cerrado that presents medicinal properties. The plant is distinguished by its large white flowers which produce a pleasant fragrance. X. aromatica is characterized by a wide range of medicinal application. These characteristics have motivated us to investigate the flowers vol

2. Antileishmanial Acetylene Fatty Acid and Acetogenins from Seeds of Porcelia macrocarpa
In the present work five acetylene derivatives (1-5), including three unknowns (1, 3 and 4), were isolated from seeds of Porcelia macrocarpa (Annonaceae). The structures of isolated compounds were determined as docos-13-yn-21-enoic acid (1), 3-hydroxy-4-methylene-2-(eicos-11’-yn-19’-enyl)but-2-enolide (2), 3-hydroxy-4-methylene-2-(octadec-9’-yn-17’-e

3. ASARONE-DERIVED PHENYLPROPANOIDS AND ISOQUINOLINE-DERIVED ALKALOIDS FROM THE BARK OF Duguetia pycnastera (Annonaceae) AND THEIR CYTOTOXICITIES
The phytochemical investigation of the hexane and methanol extracts from the bark of Duguetia pycnastera Sandwith (Annonaceae) afforded seven known compounds, two asarone-derived phenylpropanoids and five isoquinoline-derived alkaloids. The asarones, γ-asarone (1-allyl-2,4,5-trimethoxybenzene) and 2,4,5-trimethoxy-styrene were isolated of the hexane extract

4. Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe
ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the seco

5. Dereplication of Aporphine Alkaloids by UHPLC-HR-ESI-MS/MS and NMR from Duguetia lanceolata St. -Hil (Annonaceae) and Antiparasitic Activity Evaluation
Although the genus Duguetia is well known for producing alkaloids as chemical constituents, there are no reports of alkaloids identified in the species D. lanceolata. Thus, aiming to identify the chemical composition of this species, the dereplication of alkaloidic phase was performed by use of ultra-high performance liquid chromatography high resolution ele

6. DOIS NOVOS ALCALOIDES AZAFENANTRENO DE Anaxagorea dolichocarpa Sprague & Sandwith
A chemical investigation of Anaxagorea dolichocarpa Sprague & Sandwith, a member of Annonaceae family, was carried out. The ethanolic extract from the roots of this plant led, by chromatography tecniches, to isolation of the new azaphenanthrene alkaloids dolichocarpine (1) and 9-methoxyeupolauramine (2), besides the known alkaloids eupolauramine (3), 3-metho

7. Atividade antiproliferativa dos óleos essenciais de três plantas do Cerrado brasileiro: Campomanesia adamantium (Myrtaceae), Protium ovatum (Burseraceae) e Cardiopetalum calophyllum (Annonaceae)
Resumo Os óleos essenciais podem ser extraídos de várias partes das plantas e apresentam diversas atividades biológicas. O Cerrado brasileiro possui uma grande variedade de plantas produtoras de óleos essenciais muitas delas ainda não estudadas. Levando-se em consideração a biodiversidade desse bioma, o objetivo deste trabalho foi avaliar a atividad

8. Diversity of the diterpenes in the leaves of Xylopia laevigata (Annonaceae) and their cytotoxicities
The phytochemical investigation of the hexane extract which was obtained from the leaves of Xylopia laevigata (Annonaceae) produced six terpenes. Among these, five diterpenes named abieta-7,13-dien-3-one, ent-7β-acetoxy-16β-hydroxy-kaurane, 4-epi-cupressic acid, powerol, and labdorffianic acid B, and one oxygenated sesquiterpene, spathulenol. This is the f

9. MORPHOMETRIC ANALYSIS OF FRUITS AND SEEDS OF Annona crassiflora Mart. (ANNONACEAE) FROM CENTRAL BRAZIL
RESUMO Com a existente redução da cobertura vegetal do Cerrado, diversas espécies arbóreas têm suas áreas de ocorrência diminuídas e como consequência perdem parte de sua diversidade genética. Para contrapor este cenário faz-se necessário conhecer a diversidade genética afim de embasar projetos e medidas práticas de conservação. Assim, este t

10. EXTRACTION OF BIOACTIVE COMPOUNDS OF LEAVES OF Duguetia furfuracea (ANNONACEAE) USING GREEN AND ORGANIC SOLVENTS
ABSTRACT Duguetia furfuracea (Annonaceae) is a shrub found in the Brazilian Cerrado that is used in popular medicine as an antirheumatic, for wound healing, treatment of kidney pain and against pediculosis. The aim of this study was to analyze the extraction of leaves of Duguetia furfuracea, using supercritical CO2, ethanol and hexane as solvents. For the su

12. Nanoemulsion containing essential oil from Xylopia ochrantha Mart. produces molluscicidal effects against different species of Biomphalaria (Schistosoma hosts)
BACKGROUND This work describes a chemical study of the essential oil from leaves of Xylopia ochrantha, an endemic Annonaceae species from Brazil, and its activity against Biomphalaria species. Considering its poor solubility in aqueous medium, the essential oil was nanoemulsified to evaluate its action on controlling some mollusc species of genus Biomphala
