Abstract:

The genus Hedyosmum (Chloranthaceae) consists of 45 species. In Ecuador, this genus presents 16 endemic species of the high cloud forest and subpáramos of the country's south. The objective was to determine the antimicrobial activity of hexanic and ethanolic extracts from branches of Hedyosmum cuatrecazanum Occhioni., from the Ecuadorian Andes against microorganisms of clinical importance. The fresh branches of H. cuatrecazanum Occhioni. They were obtained from the natural forest of Jacarón, province of Chimborazo - Ecuador; they were dried (in an oven at 38ºC x 3 days) and then crushed. Plant

Abstract:

In Ecuador, Hedyosmum cumbalense and Hedyosmum spectabile are valued for their well-known aromatic characteristics and therapeutic benefits. In this study, fresh and dried leaves of these species were steam-distilled to obtain their essential oils (EOs) for chemical characterization and assessment of their antimicrobial, antioxidant, and anticholinesterase properties. Gas chromatography coupled to mass spectrometry (GC-MS) and a flame-ionized detector (GC-FID) with a nonpolar column was employed to determine the chemical composition, along with the enantioselective analysis.

AbstractA pollen and sediment record of a core 4.2-m-long from Laguna Baja (7°42′ S, 77°32′ W, 3575 m) in the Cordillera Oriental of northern Peru suggests several episodes of major vegetational and climatic change over the past 13,000 yr. The oldest pollen assemblage consists of a mixture of paramo elements (tropical alpine vegetation), including high percentages of Poaceae (40%) that decline upward, moist montane forest (Compositae and Polylepis), and wet montane forest (e.g., Hedyosmum and Podocarpaceae). Organic carbon content range from <2% to 8%. About 11,600 yr B.P. this mixed pollen

Abstract:

Abstract Background The Chloranthaceae comprise four extant genera (Hedyosmum, Ascarina, Chloranthus and Sarcandra), all with simple flowers. Molecular phylogenetics indicates that the Chloranthaceae diverged very early in angiosperm evolution, although how they are related to eudicots, magnoliids, monocots and Ceratophyllum is uncertain. Fossil pollen similar to that of Ascarina and Hedyosmum has long been recognized in the Early Cretaceous, but over the last four decades evidence of extinct Chloranthaceae based on other types of fossils has expanded dramatically and contributes significantly

AbstractA paleoecological record from Lake Palotoa (1370 m elevation) in the Andean foothills of Peru spans the last 3800 years. Lake Palotoa lies near the modern cloud base in a location sensitive to changes in atmospheric moisture. In many areas, these forests have been destroyed, but Lake Palotoa shows no sign of human occupation today or in the past. The modern forest surrounding the lake is dominated by the Andean palm, Dictyocaryum lamarckianum, which is also the most abundant taxon in the fossil pollen record. Fossil pollen data show the vegetation assemblages have not experienced stron

Abstract:

Ceratophyllum is an ancient and phylogenetically isolated angiosperm lineage. Comparisons between Ceratophyllum and other angiosperms are hampered by uncertainty in inferring organ homologies in this genus of specialized aquatics. Interpretation of shoot morphology is especially problematic in Ceratophyllum. Each node has several leaf-like appendages interpreted as verticillate leaves, modified parts of one and the same leaf or parts of two leaves under decussate phyllotaxis. Vegetative branches are axillary, but reproductive units (interpreted as flowers or inflorescences) are commonly viewed

Abstract:

Hedyosmum purpurascens is an endemic species found in the Andes of Ecuador and it is characterized by its pleasant smell. In this study, essential oil (EO) from H. purpurascens was obtained by the hydro-distillation method with a Clevenger-type apparatus. The identification of the chemical composition was carried out by GC–MS and GC–FID in two capillary columns, DB-5ms and HP-INNOWax. A total of 90 compounds were identified, representing more than 98% of the total chemical composition. Germacrene-D, ϒ-terpinene, α-phellandrene, sabinene, O-cymene, 1,8-cineole and α-pinene accounted for more th

Abstract:

A method to identify anticancer compounds in plants was proposed based on the hypothesis that these compounds are primarily present in plants to provide them with an ecological advantage over neighboring plants and other competitors. According to this view, identifying plants that contain compounds that inhibit or interfere with the development of other plant species may facilitate the discovery of novel anticancer agents. The method was developed and tested using Magnolia grandiflora, Gynoxys verrucosa, Picradeniopsis oppositifolia, and Hedyosmum racemosum, which are plant species known to po

Abstract:

AbstractThe characterization of modern pollen rain assemblages along environmental gradients is an essential prerequisite for reliable interpretations of fossil pollen records. In this study, we identify pollen-vegetation relationships using modern pollen rain assemblages in moss polsters (n = 13) and lake sediment surface samples (n = 11) along a steep temperature gradient of 7°C (3100–4200 m above sea level) on the western Andean Cordillera, Ecuador. The pollen rain is correlated to vascular plant abundance data recorded in vegetation relevées (n = 13). Results show that pollen spectra from

Con el fin de determinar la calidad de la miel de Apis mellifera variedad scutellata, procedentes de las subregiones del Suroeste y Oriente Antioqueño, producidas durante los años 2013 y 2014, se realizó un estudio fIsicoquímico y palinológico de 18 muestras. El análisis fIsicoquímico reveló que todos los parámetros analizados se encontraban dentro de los valores establecidos por la normatividad Colombiana, con muy pocas excepciones. En general todas las mieles analizadas fueron de buena calidad y las variaciones en los parámetros analizados, fueron relacionadas con el origen botánico y geográ

Abstract:

The present study aimed to determine the chemical composition, enantiomeric distribution and the biological profile of Hedyosmum strigosum essential oil (EO). The antioxidant properties and anticholinesterase effect were measured by spectroscopic methods and antimicrobial potency assessed against 8 bacteria and two fungi. H. strigosum is a native shrub, particularly found in Ecuador and Colombia at 2000 to 3500 m a.s.l. Chemical composition was determined by GC-MS and GC-FID. A total of 44 compounds were detected, representing more than 92% of the EO composition. The main compounds were thymol
