La comparaison par spectrométrie de masse des fractions flavonoïdiques de A. salicifolia et A. polyphylla a permis d'identifier neuf composés supplémentaires. Deux composés sont spécifiques de A. salicifolia et permettent de distinguer chimiquement les deux espèces. ABSTRACT : This report contributes to complete the phytochemical knowledge on four plants: Agauria salicifolia Hook.f ex Oliver, Agauria polyphylla Baker (Ericaceae), Tambourissa trichophylla Baker (Monimiaceae) and, Embelia concinna Baker (Myrsinaceae) used in traditional medicine in Madagascar. Four compounds were isolated from the extracts of the Agauria: a flavonoid type compound and a triterpene. Three flavonol O-glycosides were isolated from T. trichophylla extracts. The study of E. concinna led to the isolation and characterization of a triterpènes, six flavonoïdes, a phenolic acid, a fatty acid and an alkylresorcinol. The use of these compounds as phytochemical markers was evaluated. Identification of the compounds was carried out by interpretation of MS, MS/MS, 1D and 2D NMR spectra. Liquid chromatography coupled mass spectrometry was used to compare the flavonoid fractions of A. salicifolia and A. polyphylla. Two flavonol O-glucuronides were found to differentiate the two populations

    Abstract:

    Components of essential oils from the Chilean Monimiaceae, boldo (Peumus boldus Mol.), tepa (Laureliopsis philippiana (Looser) Schodde), and laurel (Laurelia sempervirens (Ruiz & Pav.) Tul.) were determined using Gas Chromatography- Mass Spectrometry (GCMS) and fungistatic activity of the essential oils was tested against Rhizoctonia solani Kuhn (Donk), Pythium irregulare Buisman, Ceratocystis pilifera (Fr.) C. Moreau, Phragmidium violaceum (Schultz) G. Winter, and Fusarium oxysporum Schltdl. The essential oils of the Monimiaceae species shared some common components; all three had the 3-carene, α-phellandrene, and α-pinene terpenes. L. philippiana and L. sempervirens also had safrole.The main components were ascaridol in P. boldus oil, 3-carene in L. philippiana, and safrole in L. sempervirens. The essential oil from L. sempervirens showed the highest fungistatic activity with significant differences in dose as well as exposure. P. violaceum was the most sensitive strain and P. irregulare the most resistant of all the essential oils (P. boldus extract affected growth by only 19%). Therefore, essential oils from these three plants could be used to control the fungal strains studied.

Tul.) a través de cromatografía de gas con espectrometría de masas (CG-EM) y se midió la actividad fungistática de los aceites sobre los hongos Rhizoctonia solani Kühn (Donk), Pythium irregulare Buisman, Ceratocystis pilifera (Fr.) C. Moreau, Phragmidium violaceum (Schultz) Winter y Fusarium oxysporum Schltdl. Los aceites esenciales de las especies de Monimiaceae tienen algunos compuestos en común; en las especies estudiadas se encontró que todos tenían los terpenos 3-careno, α-felandreno, y α-pineno. L. philippiana y L. sempervirens además tienen safrol. En cambio, ascaridol fue el principal compuesto en el aceite de P. boldus, 3-careno en L. philippiana y safrol en L. sempervirens. El aceite esencial de L. sempervirens presentó la mejor actividad fungistática contra las cepas tratadas, con diferencias significativas tanto en dosis como en tiempo de exposición. P. violaceum fue la cepa más sensible a los aceites esenciales y P. irregulare la más resistente (el extracto de P. boldus detuvo el crecimiento sólo un 19%). Por lo tanto, los aceites esenciales de todos estos árboles podrían ser usados como controladores de las cepas de hongos estudiadas

  • Vol. 1/1, pp. 61–77 © Gustav Fischer Verlag, 1998 Phylogenetic affinities of Monimiaceae based on cpDNA gene and spacer sequences
    2015
    Co-Authors: Susanne S. Renner
    Abstract:

    Nucleotide sequence data from the chloroplast rbcL gene and the trnL-trnF intergenic spacer of 58 species in 38 genera were used to infer the phylogenetic affinities of Monimiaceae to other Laurales, and to assess whether the family in the traditional wide sense is monophyletic. Besides Monimiaceae, the Laurales comprise Calycan-thaceae, Gomortegaceae, Hernandiaceae, and Lauraceae. Magnoliaceae and Myris-ticaceae were used as outgroups. Based on recent molecular data, Amborellaceae and Chloranthaceae, which have sometimes been included in the order, do not be-long in the Laurales, and indeed trnL-trnF sequences of Amborella (Amborellaceae) and Hedyosmum (Chloranthaceae) were too different to be unambiguously aligned with the remaining sequences. Parsimony analyses of the trnL-trnF and trnL-trnF-rbcL data groups the genera into five major clades, Calycanthaceae, Atherosperma-taceae, Gomortega, Siparunaceae, and a weakly supported Monimiaceae s.str.-Lau-raceae-Hernandiaceae clade. RbcL data alone provide no resolution at the family level. Many aspects of traditional intra-familiar classification of Monimiaceae are sup

  • biogeography of the Monimiaceae laurales a role for east gondwana and long distance dispersal but not west gondwana
    Journal of Biogeography, 2010
    Co-Authors: Susanne S. Renner, Joeri S Strijk, Dominique Strasberg, Christophe Thebaud
    Abstract:

    Aim  The biogeography of the tropical plant family Monimiaceae has long been thought to reflect the break-up of West and East Gondwana, followed by limited transoceanic dispersal. Location  Southern Hemisphere, with fossils in East and West Gondwana. Methods  We use phylogenetic analysis of DNA sequences from 67 of the c. 200 species, representing 26 of the 28 genera of Monimiaceae, and a Bayesian relaxed clock model with fossil prior constraints to estimate species relationships and divergence times. Likelihood optimization is used to infer switches between biogeographical regions on the highest likelihood tree. Results Peumus from Chile, Monimia from the Mascarenes and Palmeria from eastern Australia/New Guinea form a clade that is sister to all other Monimiaceae. The next-deepest split is between the Sri Lankan Hortonia and the remaining genera. The African Monimiaceae, Xymalos monospora, then forms the sister clade to a polytomy of five clades: (I) Mollinedia and allies from South America; (II) Tambourissa and allies from Madagascar and the Mascarenes; (III) Hedycarya, Kibariopsis and Leviera from New Zealand, New Caledonia and Australia; (IV) Wilkiea, Kibara, Kairoa; and (V) Steganthera and allies, all from tropical Australasia. Main conclusions  Tree topology, fossils, inferred divergence times and ances-tral area reconstruction fit with the break-up of East Gondwana having left a still discernible signature consisting of sister clades in Chile and Australia. There is no support for previous hypotheses that the break-up of West Gondwana (Africa/South America) explains disjunctions in the Monimiaceae. The South American Mollinedia clade is only 28–16 Myr old, and appears to have arrived via trans-Pacific dispersal from Australasia. The clade apparently spread in southern South America prior to the Andean orogeny, fitting with its first-diverging lineage (Hennecartia) having a southern-temperate range. The crown ages of the other major clades (II–V) range from 20 to 29 Ma, implying over-water dispersal between Australia, New Caledonia, New Zealand, and across the Indian Ocean to Madagascar and the Mascarenes. The endemic genus Monimia on the Mascarenes provides an interesting example of an island lineage being much older than the islands on which it presently occurs.

  • Circumscription and phylogeny of the Laurales: evidence from molecular and morphological data.
    American Journal of Botany, 1999
    Co-Authors: Susanne S. Renner
    Abstract:

    The order Laurales comprises a few indisputed core constituents, namely Gomortegaceae, Hernandiaceae, Lauraceae, and Monimiaceae sensu lato, and an equal number of families that have recently been included in, or excluded from, the order, namely Amborellaceae, Calycanthaceae, Chloranthaceae, Idiospermaceae, and Trimeniaceae. In addition, the circumscription of the second largest family in the order, the Monimiaceae, has been problematic. I conducted two analyses, one on 82 rbcL sequences representing all putative Laurales and major lineages of basal angiosperms to clarify the composition of the order and to determine the relationships of the controversal families, and the other on a concatenated matrix of sequences from 28 taxa and six plastid genome regions (rbcL, rpl16, trnT-trnL, trnL-trnF, atpB-rbcL, and psbA-trnH) that together yielded 898 parsimony-informative characters. Fifteen morphological characters that play a key role in the evolution and classification of Laurales were analyzed on the most parsimonious molecular trees as well as being included directly in the analysis in a total evidence approach. The resulting trees strongly support the monophyly of the core Laurales (as listed above) plus Calycanthaceae and Idiospermaceae. Trimeniaceae form a clade with Illiciaceae, Schisandraceae, and Austrobaileyaceae, whereas Amborellaceae and Chloranthaceae represent isolated clades that cannot be placed securely based on rbcL alone. Within Laurales, the deepest split is between Calycanthaceae (including Idiospermaceae) and the remaining six families, which in turn form two clades, the Siparunaceae (Atherospermataceae-Gomortegaceae) and the Hernandiaceae (Monimiaceae s.str. [sensu stricto]-Lauraceae). Monimiaceae clearly are polyphyletic as long as they include Atherospermataceae and Siparunaceae. Several morphological character state changes are congruent with the molecular tree: (1) Calycanthaceae have disulculate tectate-columellate pollen, while their sister clade has inaperturate thin-exined pollen, with the exception of Atherospermataceae, which have columellate but meridionosulcate or disulcate pollen. (2) Calycanthaceae have two ventral ovules while their sister clade has solitary ovules. Within this sister clade, the Hernandiaceae (Lauraceae-Monimiaceae) have apical ovules, while the Siparunaceae (Atherospermataceae-Gomortegaceae) are inferred to ancestrally have basal ovules, a condition lost in Gomortega, the only lauralean genus with a syncarpous ovary. (3) Calycanthaceae lack floral nectaries (except for isolated nectarogeneous fields on the inner tepals), while their sister clade ancestrally has paired nectar glands on the filaments. Filament glands were independently lost in higher Monimiaceae and in Siparunaceae concomitant with pollinator changes away from nectar-foraging flies and bees to non-nectar feeding beetles and gall midges. (4) Disporangiate stamens with anthers dehiscing by two apically hinged valves are ancestral in Siparunaceae-(AtherospermataceaeGomortegaceae) and evolved independently within Hernandiaceae and Lauraceae. Depending on the correct placement of Calycanthaceae-like fossil flowers, tetrasporangiate anthers with valvate dehiscence (with the valves laterally hinged) may be ancestral in Laurales and lost in modern Calycanthaceae and Monimiaceae.

The essential oil from L. sempervirens showed the highest fungistatic activity with significant differences in dose as well as exposure. P. violaceum was the most sensitive strain and P. irregulare the most resistant of all the essential oils (P. boldus extract affected growth by only 19%). Therefore, essential oils from these three plants could be used to control the fungal strains studied.

Therefore, essential oils from these three plants could be used to control the fungal strains studied.Se determinaron los compuestos de aceites esenciales de Monimiaceae chilenas, boldo (Peumus boldus Mol.), tepa (Laureliopsis philippiana (Looser) Schodde), y laurel (Laurelia sempervirens (Ruiz & Pav.) Tul.) a través de cromatografía de gas con espectrometría de masas (CG-EM) y se midió la actividad fungistática de los aceites sobre los hongos Rhizoctonia solani Kühn (Donk), Pythium irregulare Buisman, Ceratocystis pilifera (Fr.) C. Moreau, Phragmidium violaceum (Schultz) Winter y Fusarium oxysporum Schltdl. Los aceites esenciales de las especies de Monimiaceae tienen algunos compuestos en común; en las especies estudiadas se encontró que todos tenían los terpenos 3-careno, α-felandreno, y α-pineno. L. philippiana y L. sempervirens además tienen safrol. En cambio, ascaridol fue el principal compuesto en el aceite de P. boldus, 3-careno en L. philippiana y safrol en L. sempervirens. El aceite esencial de L. sempervirens presentó la mejor actividad fungistática contra las cepas tratadas, con diferencias significativas tanto en dosis como en tiempo de exposición. P. violaceum fue la cepa más sensible a los aceites esenciales y P. irregulare la más resistente (el extracto de P. boldus detuvo el crecimiento sólo un 19%). Por lo tanto, los aceites esenciales de todos estos árboles podrían ser usados como controladores de las cepas de hongos estudiadas
