The mucilage obtained from cladodes of Opuntia spinulifera has been used in industries and traditional applications. In the present work, chemical, morphological, thermal structural features cladode Salm-Dyck were studied. 2D 1H-1H COSY NMR confirmed ten different residues within repeating saccharide unit, six with α four β configurations. FTIR showed presence galactose pectins. XRD detected minerals as calcium salts. SEM exhibited aggregations irregular morphology particles. TGA registered...
Genomic DNA extracted from species of Cactaceae is often contaminated with significant amounts mucilage and pectin. Pectin one the main components cellular walls, whereas a complex polysaccharide ramified structure. Thus, pectin- mucilage-free extraction key step for further downstream PCR-based analyses.We tested our method on cladode tissue (juvenile, adult, herbaria exemplars) 17 Opuntia Mill., which are characterized by large quantity pectin mucilage.We developed gDNA free inhibitory...
Introduction . Xoconostles or acidic cactus pears (Opuntia spp.) are fruits prized for their fleshy and mesocarp; they morphologically different from which sweet, juicy seedy. Both thrive in semiarid highlands of Central Mexico, tolerate poor soils scanty rainfall, have evolved into formal crops during the last five decades. Wild xoconostles ubiquitous Mexican regions. Domesticated genotypes found backyards commercial orchards. Folk wisdom attributes xoconostle with antihypoglycemic effects,...
Introduction. The genus Opuntia generally produces fruits with abundant pulp and sweet taste, but also acidic known as xoconostles, which may have a high potential for use consumption. aim of this study was to evaluate the physicochemical, nutritional functional characteristics 10 xoconostle genotypes produced in Mexico. Materials methods. were collected from Hidalgo, Zacatecas State Mexico pH, soluble solids, titratable acidity, well proximate composition content total phenolic compounds,...
El objetivo de la presente investigación fue determinar el contenido algunos compuestos bioactivos y capacidad antioxidante xocotuna (Opuntia chiangiana) en comparación con tuna ficus-indica) xoconostle spp.). Se cosecharon frutos madurez fisiológica durante los meses junio, agosto octubre 2013 municipio Orito, Zacatecas, México. Las variables evaluadas fueron: antioxidante, fenoles totales, vitamina C, betalaínas, clorofila total carotenos. observó que cultivar 'Coral' presentó diferencias...
This study determined nutritional quality, content of antioxidant compounds and antioxidantactivity in the rind (mesocarp) fruit 15 genotypes xoconostle to identify those thathave greater nutraceutical potential. A proximal analysis was conducted. Contents ofbetalain, total phenolic compounds, flavonoids, ascorbic acid activity werequantified. The data obtained were analyzed with an variance (ANOVA), theTukey test (P ? 0.05) Pearson coefficient correlation. Significant differences...
Se describe e ilustra la Opuntia perotensis Scheinvar, Olalde & Gallegos, nueva especie de un nopal silvestre del Frijol Colorado, Cofre Perote, Veracruz, México. La estaba identificada como O. huajuapensis Bravo en el herbario Instituto Investigaciones Biológicas Universidad Veracruzana. es una endémica mixteca oaxacense, distinguiéndose , cual presenta epidermis papilosa, cladodios con espinas todas las aréolas, algunos pelos negros; flores dos colores; frutos subglobosos paredes...
We describe a new species of wild Mexican Opuntia producer edible acidic prickly pears (xoconostles), locally known as “xoconostle de cerro blanco“ (white hillside xoconostle), based on external morphology and micromorphology attributes (mainly characters the spines). This is morphologically compared with another four xoconostles distributed in same region: O. joconostle, leiascheinvariana, oligacantha matudae. A taxonomic key for area provided. Based phylogenetic analysis one chloroplast...
This study had the objective of characterizing 40 nopal cultivars for use as a vegetable in germplasm collection CRUCEN-UACh based on morphological attributes one-year-old mature cladodes and to numerically classify those genotypes. Fourteen qualitative quantitative variables were considered this purpose: 10 that undamaged by biotic or abiotic factors selected. The analysis method was multivariate main components conglomerates which allowed grouping into five classes. Tapón Macho, Copena F-1...
A detailed morphological and molecular study on Opuntia matudae O. hyptiacantha is presented. These two species have been long considered to belong the same taxon, although no investigations were carried out in depth. Moreover, published phylogenetic of genus include both species. Our data support recognition as different unrelated
Se describe una nueva especie silvestre de Opuntia (L.)Mill. (Cactaceae) frutos comestibles ácidos (xoconostles), conocida localmente como “xoconostle matizado”, basados en micromorfología (areola, espina, glóquida, polen y semilla) morfología externa. compara morfológicamente con otras tres especies silvestres distribuidas la misma región: O. joconostle , oligacantha matudae . Con base el análisis filogenético un gene cloroplasto, espaciador intergénico cloroplasto marcador nuclear se...
Numerical classifications in biology have been based on genetics and phylogenetics. This research report presents the case of developing a strategy for an objective ordering numerical classification terms fruit mass shape (prickly pear, tuna, or nochtli) genus Opuntia. The advantages principal components (PC's) Opuntia accessions are described, convenience using cluster analysis same purpose is discussed. A way defining number groups statistical fundaments described. Likewise, importance...
Estudiar la morfología interna de semillas duras es un reto, debido a dificultad para cortar este tipo especímenes. La presente técnica usa una lima desgastar semilla hasta obtener el corte en plano mediano. superficie limada se fotografía bajo microscopio estereoscópico imagen digital, cual estudia mediante programa análisis imágenes datos cualitativos y cuantitativos estructura interna. Los pueden someter diferentes estadísticos. Como ejemplo aplicación esta presenta estudio comparativo...
