  • Contenido de Compuestos Fenólicos y Capacidad Antioxidante de Inga edulis “Guava” y Pouteria sapota “Zapote”
    'Universidad Cesar Vallejo', 2019
    Co-Authors: De Los Ríos Deza Cecilia
    Abstract:

    El objetivo de esta investigación fue evaluar los compuestos fenólicos y la capacidad antioxidante de Inga edulis “Guaba” del distrito de San Pedro de Lloc- Pacasmayo y Pouteria Sapota “Zapote” de Bagua grande. Los métodos a usar fue Folin Ciocalteu para determinar compuestos fenólicos y el método DPPH (2,2-difenil-1-picrilhidrazilo) para medir la capacidad antioxidante de ambos frutos. Con respecto al contenido de compuestos fenólicos en la evaluación de Inga Edulis “Guaba” se obtuvo 15.39±1.88 µg equivalente en Acido Galico (EAG) /100g de muestra, mientras que en Pouteria sapota "sapote" fue correspondiente a 15.63±0.61 µg EAG/100g. En referencia a la capacidad antioxidante se expresó en IC50 (concentración del extracto para inhibición al 50%), en el caso del extracto hidroalcohólico (80%) de Inga Edulis “Guaba” se encontró 913.73 µg/ml y para Pouteria sapota "sapote 759.88 µg/ml, concluyéndose así que la capacidad antioxidante de Pouteria sapota "sapote" y la capacidad de Inga Edulis “Guaba” es baj

    Abstract:

    RESUMEN Se determino el periodo de desarrollo del fruto de zapote mamey [ Pouteria sapota (Jacq.) H. E. Moore & Stearn], asi como su patron de crecimiento mediante el diametro polar y ecuatorial; tambien se definio el periodo donde ocurre la mayor abscision de fruto y la dis-tribucion de la masa en las estructuras del mismo. El crecimiento del fruto de mamey desde flor a fruto fisiologicamente maduro, duro en-tre 18 y 20 meses, con un patron de crecimiento sigmoidal. La mayor caida de frutos (76 %) se presento cinco meses antes de la floracion siguiente. En promedio, los frutos cosechados representaron 20 % del total inicial, y la cosecha fue en los meses de febrero a mayo. La masa del fruto se incremento despues del mes de abril en un patron sigmoi-dal; 60 % de la masa se asigno a pulpa, 25 % a cascara y 15 % a se-milla, cerca de la cosecha. Palabras clave: Pouteria sapota , crecimiento, fenologia, abscision. SUMMARY The growth pattern and time to full fruit development in sapote mamey [

  • multi gene phylogeny of the pantropical subfamily chrysophylloideae sapotaceae evidence of generic polyphyly and extensive morphological homoplasy
    Cladistics, 2008
    Co-Authors: Ulf Swenson, James E Richardson, Igor V Bartish
    Abstract:

    We present a molecular phylogeny of 26 out of the 28 currently accepted genera in the subfamily Chrysophylloideae (Sapotaceae) using parsimony, parsimony jackknifing, and Bayesian inference. A data matrix of 8984 characters was obtained from DNA sequences of seven chloroplast loci, two nuclear loci, indels coded as binary characters, and morphology. Our phylogenetic reconstruction suggests that Chrysophyllum, Pouteria, and Pradosia, as well as some sections within Chrysophyllum and Pouteria, are all polyphyletic. These taxa were previously described largely on the basis of unique combinations of states for a set of morphological characters. Mapping some of these characters onto one of the most parsimonious trees indicates that the symplesiomorphic flower in the subfamily was probably 5-merous, had stamens inserted in the tube orifice, staminodes, seeds with foliaceous cotyledons, exserted radicle, and endosperm. These characters have subsequently been lost multiple times and cannot be used as synapomorphies to support broad generic concepts. Despite the high degree of homoplasy some well-defined clades can be described on the basis of alternative character state combinations. Also, many of these well-supported clades appear to be restricted to particular geographical areas (e.g. all taxa in Australasia form a monophyletic group). Hence, we suggest that the segregate genera Aningeria, Malacantha, and Martiusella may ultimately be resurrected, and probably also Donella and Gambeya, but their circumscriptions are still unclear. One species, Chrysophyllum cuneifolium, may have originated from a hybridization event between continents where the maternal genome (cpDNA) comes from South America and the nuclear genome comes from Africa. © The Willi Hennig Society 2008.
