The objective of this study was to evaluate the influence King Abdulaziz University of seasonality on the essential oil of V. curassavica accessions. Leaves from six accessions were collected Saudi Arabia from the Germplasm Bank of the Federal University of Minas Gerais over 12 months. Correlations between the essential oil content and meteorological factors were determined. Gas chromatography Ivan Montenegro analysis coupled with mass spectrometry was conducted to determine the chemical composition of the Universidad de Valparaíso essential oil. The content and chemical composition of the oil varied throughout the year. Relative Chile humidity was correlated with accessions ICA-VC2 (-0.64) and ICA-VC4 (0.68). β-bourbonene, β- elemene, spathulenol, germacrene, caryophyllene oxide, α-humulene, and β-caryophyllene occurred in all accessions. Accession ICA-VC3 exhibited lower variation (22.17%), higher average (0.97%) essential oil, and maintained an average abundance of α-humulene greater than 2.6%, which is the amount necessary for phytotherapeutics.

  • Biogeochemical Relationships of a Subtropical Dry Forest on Karst
    2017 CARIBBEANCaribbean Naturalist NATURALIST No. 41:1–24No. 41 E. Medina, E. Cuevas, H. Marcano-Vega, E. Meléndez-Ackerman, and E.H. Helmer Biogeochemical Relationships of a Subtropical Dry Forest on Karst Ernesto Medina1,2,*, Elvira Cuevas3, Humfredo Marcano-Vega4, Elvia Meléndez-Ackerman3, and Eileen H. Helmer1 Abstract - Tropical dry forests on calcareous substrate constitute the main vegetation cover in many islands of the Caribbean. Dry climate and nutrient scarcity in those environments are ideal to investigate the potential role of high levels of soil calcium (Ca) in regulating plant selection and productivity. We analyzed the elemental composition of soil, loose lit- ter, and leaf samples of the woody vegetation on the plateau of Mona Island, an emergent block of carbonate rock in the Caribbean located between Puerto Rico and the Dominican Republic, to explore the nutrient relationships of plants growing on calcareous substrates. The mineral soil has an elemental composition characterized by high levels of aluminum (Al) and iron (Fe) in agreement with the hypothesis that it derives in part from sediments transported by rivers eroding plutonic rocks, and deposited before the massive lifting of biological limestone. Calcium concentration varied within sites, and Ca–Al and Ca–Fe cor- relations were negative in soils and positive in plant material, implying that element uptake from these soils depends on acidification of the rhizosphere. This acidification should be high enough to extract carbonate-bound elements and solubilize Al, Fe, and probably phos- phate (P) compounds. The most abundant cation in leaves was Ca, followed by potassium (K) and magnesium (Mg); Ca/K and Ca/Mg molar ratios averaged 2 and 3, respectively, in- dicating that most species maintain K and Mg uptake in the presence of high Ca levels.

Indeed, restingas have experienced a continuous process of degradation, and thus, with species and ecosystem both at risk, efforts to support conservation actions are required. The present study aimed to evaluate aspects of V. curassavica reproductive biology. To accomplish this, morphological characterization was performed by monitoring flowering events. The availability of nectar and pollen, as well as the frequency and behavior of floral visitors and dispersers, was also evaluated. This species exhibits both heterostyly and protogyny. Anthesis is diurnal, and flowers last less than a day. The high number of flower and fruit abortions suggests that mechanisms, such as self-incompatibility intra-morphs and easily detached flowers, contribute to reduced fruit production. The high diversity of floral visitors indicate a generalist pollination syndrome. Diptera, Hymenoptera and Lepidoptera were the main pollinators, and nectar was the main resource sought by these insects.

  • Characterisation of a Novel Fruit Type Found in Ehretia (Ehretiaceae, Boraginales)
    BLUMEA 49: 145–153 Published on 3 May 2004 doi: 10.3767/000651904X486250 CHARACTERISATION OF A NOVEL FRUIT TYPE FOUND IN EHRETIA (EHRETIACEAE, BORAGINALES) MARC GOTTSCHLING1, 2 & HARTMUT H. HILGER1 SUMMARY Ehretia (Ehretiaceae, Boraginales) has been divided into two major clades, characterised by fruits with four endocarpids (Ehretia I, including species of Ehretia formerly belonging to Rotula) and by fruits with two endocarpids (Ehretia II, plus E. microphylla (= Carmona retusa) with an undivided endocarp), respectively. Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group). Its representatives are characterised by four endocarpids (as in Ehretia I), but differ in the presence of distinct lamellae on the abaxial surface of each endocarpid (as in Bourreria, also belonging to Ehretiaceae). However, molecular data suggest a close relationship with Ehretia II. At least three species belong to Ehretia III: Chinese E. longiflora, eastern Indian E. wallichiana, and Indonesian E. javanica. Key words: Ehretia longiflora, anatomy, fruit, ITS1, molecular systematics, phylogeny, phylo- geography. INTRODUCTION Ehretiaceae (Boraginales) are pantropical in distribution (with centres of diversity in Central America, Africa, and East Asia) and comprise about 150 species. The plants are usually subshrubs, shrubs, or trees, and otherwise have the typical asterid characters such as tetracyclic, pentamerous flowers with five antesepalous stamens and bicarpel- late gynoecia. Fruit morphology provides a systematically important set of characters in Ehretiaceae (Pitot, 1939a, b; Miller, 1989; Verdcourt, 1991; Gottschling & Hilger, 2001). Most of the species of Ehretiaceae have drupes (otherwise dry nutlets), with either undivided, two-, or four-parted endocarps. The individual parts of the two- and four-parted endocarps are termed endocarpids and enclose two seeds or one seed each, respectively.

(Syn. Cordia verbenaceae). The essential oils were extracted by hydrodistillation and analyzed by comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC GC-MS). The GC GC approach a three-fold × × improvement in qualitative analysis (48 compounds were identified by GC-MS versus 135 by GC GC-MS). The improved resolving power of GC GC resolved important coelutions and enabled × × the detection of unusual substances in V. curassavica essential oil. The chromatographic data was analyzed by using peak table-based chemometrics, namely, principal component analysis (PCA) and hierarchical cluster analysis (HCA). The metabolic study showed that seasonality has a significant effect on the chemical composition. The α-humulene content was affected by genotype and season. Spring and summer were the best harvest seasons for the yield of the active ingredient, found in higher concentrations in the VC2 genotype.

Varronia curassavica Jacq., Boraginaceae, is a native medicinal species Accepted 26 August 2014 from Brazil known as “erva-baleeira”, with anti-inflammatory activity related to its essen- tial oil. Despite pharmacological evidences of this species and its economic importance for Keywords: herbal medicine production, little is known about the effect of light on growth and essential Cordia verbenacea oil production. This study aimed to analyze the influence of different irradiances on growth, Irradiance frequency of trichomes, essential oil yield and composition of V. curassavica. The irradiance Medicinal plant affected plant growth, but no significant alteration on leaf biomass was detected. The in- Caryophyllene oxide crease in essential oil content under higher irradiance reflected on essential oil yield, and is associated with higher frequency of glandular, globular trichomes. The essential oil com- position, rich in caryophyllene derivatives was affected by irradiance, but α-humulene, the constituent of pharmaceutical interest, remained unchanged. © 2014 Sociedade Brasileira de Farmacognosia.
