The information about chemical composition of atemoya is scarce. The mineral composition was evaluated employing Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) and the centesimal composition and the physico-chemical parameters were assessed employing procedures described in the AOAC methods. The total phenolic compounds (TPC) and total flavonoids (TF) were determined using spectroanalytical methods.

  • Cherimoya and Guanabana in the Archaeological Record of Peru
    Journal of Ethnobiology 17(2):235-248 Winter 1997 CHERIMOYA AND GUANABANA IN THE ARCHAEOLOGICAL RECORD OF PERU THOMAS POZORSKI AND SHELIA POZORSKI Department of Psychology and Anthropology University of Texas-Pan American Edinburg, TX 78539 ABSTRACT.-Most researchers commonly assume that both cherimoya (Annona cherimolia) and guanabana (Annona muricata) have long been a part of the prehistoric record of ancient Peru. However, archaeological and ethnohistoric research in the past 25years strongly indicates that cherimoya was not introduced into Peru until ca. A.D. 1630 and that guanabana is only present after ca. A.D. 1000and is mainly associated with sites of the Chimu culture. RESUMEN.-La mayorfa de los investigadores suponen que tanto la chirimoya (Annona cherimola)como la guanabana (Annona muricata) han sido parte del registro prehist6rico del antiguo Peru por largo tiempo . Sin embargo, las in vestigaciones arqueol6gicas y etnohist6ricas de los ultimos veinticinco afios indican fuertemente que la chirimoya no fue introducida al Peru sino hasta 1630 D.C., Y que la guanabana esta presente s610 despues de aproximadamente 1000 D.C., Y esta asociada principalmente con sitios de la cultura chirmi. RESUME.- La plupart des chercheurs supposent couramment qu'une espece de pomme cannelle (Annonacherimolia)et le corossol (Annona muricata) ont faitpartie, pendant une longue periode, de l'inventaire prehistorique du Perou. Toutefois, les recherches archeologiques et ethnohistoriques des vingt-cinq dern ieres annees indiquent fortement que la pomme cannelle A. cherimolia ne fut introduite au Perou qu'aux environs de 1630 apr. J.-c. et la presence du corossol n'est attestee qu'en 1000apr.

  • Native Trees of Georgia
    1 NATIVE TREES OF GEORGIA By G. Norman Bishop Professor of Forestry George Foster Peabody School of Forestry University of Georgia Currently Named Daniel B. Warnell School of Forest Resources University of Georgia GEORGIA FORESTRY COMMISSION Eleventh Printing - 2001 Revised Edition 2 FOREWARD This manual has been prepared in an effort to give to those interested in the trees of Georgia a means by which they may gain a more intimate knowledge of the tree species. Of about 250 species native to the state, only 92 are described here. These were chosen for their commercial importance, distribution over the state or because of some unusual characteristic. Since the manual is intended primarily for the use of the layman, technical terms have been omitted wherever possible; however, the scientific names of the trees and the families to which they belong, have been included. It might be explained that the species are grouped by families, the name of each occurring at the top of the page over the name of the first member of that family. Also, there is included in the text, a subdivision entitled KEY CHARACTERISTICS, the purpose of which is to give the reader, all in one group, the most outstanding features whereby he may more easily recognize the tree. ACKNOWLEDGEMENTS The author wishes to express his appreciation to the Houghton Mifflin Company, publishers of Sargent’s Manual of the Trees of North America, for permission to use the cuts of all trees appearing in this manual; to B. R. Stogsdill for assistance in arranging the material; to W.

ABSTRACT OF THESIS CHARACTERIZATION OF POLYPHENOL OXIDASE AND ANTIOXIDANTS FROM PAWPAW (ASIMINA TRIBOLA) FRUIT Crude polyphenol oxidase (PPO) was extracted from pawpaw (Asimina triloba) fruit. The enzyme exhibited a maximum activity at pH 6.5–7.0 and 5–20 °C, and had -1 a maximum catalysis rate (Vmax) of 0.1363 s and a reaction constant (Km) of 0.3266 M. It was almost completely inactivated when incubated at 80 °C for 10 min. Two isoforms of PPO (MW 28.2 and 38.3 kDa) were identified by Sephadex gel filtration chromatography and polyacrylamide gel electrophoresis. Both the concentration and the total activity of the two isoforms differed (P < 0.05) between seven genotypes of pawpaw tested. Thermal stability (92 °C, 1–5 min) and colorimetry (L* a* b*) analyses showed significant variations between genotypes.

Boa Vista/RR, Brasil 3Empresa Brasileira de Pesquisa Agropecuária, Boa Vista, RR, Brasil. CNPq Research Productivity Scholarship. *Corresponding author: [email protected] Abstract Sugar apple (Annona squamosa L.) is a commercially significant fruit species due to its nutritional qualities. The state of Roraima has excellent soil and climatic conditions for the cultivation of the species. However, no studies on the phenological behavior of this plant have been reported in the literature. In this context, the objective of this work was to investigate the vegetative and reproductive phenological behavior of sugar apple under the savanna conditions of the state of Roraima. The experiment was carried out in four seasons of the year (2014/2014 and 2015/2015 rainy season and 2014/2015 and 2015/2016 Summer). Production pruning was carried out in February 2014 (2014.1 cycle), September 2014 (2014.2 cycle), February 2015 (2015.1 cycle) and September 2015 (2015.2 cycle). Forty plants were monitored during the experiment and evaluated every three days for the following variables: beginning date of bud swelling; duration of flowering; and fruit harvest time.

  • Morphological Description of Jogorogo Mangosteen (Garcinia Mangostana L.)
    Journal of Biotechnology and Biodiversity, April 2010; 1(1): 20-25 ISSN: 2087-0183 RESEARCH Morphological description of Jogorogo Mangosteen (Garcinia mangostana L.) Endang Yuniastutia* aDepartment of Agrotechnology, Faculty of Agriculture, Sebelas Maret University, Jl. Ir. Sutami no 36A, Surakarta 57126, Indonesia Received : 14 December 2009 Accepted: 2 February 2010 Abstract This research aimed to obtain phenotypic information based on morphological character of Jogorogo Mangosteen (Garcinia mangostana L.). This research was conducted with direct observation through primary and secondary data recording, and documenting parts of Jogorogo Mangosteen plant specifically, that was, in vegetative part: stalk and leave, as well as generative part: flower, fruit and seed. Jogorogo Mangosteen may reach hundreds years of life span, it had an average height of 9 meters, stalk diameter of 1 meter and crown diameter of 6 meter. The tree crown of Jogorogo Mangosteen plant was triangular in shape, with horizontal and irregular branching pattern and various densities. The leaves of Jogorogo Mangosteen were elliptic. The tip of the leaf was pointed, the base of the leaf was blunt, and the leaf edge was flat with the smooth and shining surface. The flower of Jogorogo Mangosteen was a hermaphrodit and a perfect flower. The fruit was small with 59 grams weight/flower with 4.5 cm long and 4.45 cm wide. The fruit was purple- blackish with the continuous fruit ripening with high fruit bearing level. The Jogorogo Mangosteen fruit was sweet with a little yellow sap. 1-2 seeds were formed in every Jogorogo Mangosteen fruit with 1.6 cm long, 0.8 cm wide and 2.75 thick.
