Chemical Composition and Antioxidant Potential Differences between Cynomorium coccineum L. Growing in Italy and in Tunisia: Effect of Environmental Stress

Cynomorium coccineum is a parasitic plant that has been known for centuries in ethnopharmacology. However, its biological activities have been scarcely studied, particularly in the case of plant grown in North Africa. Thus, we compared the chemical composition and antioxidant potential of C. coccineum taken from two regions characterized by very different climates: the Tataouine region in southeast Tunisia, which lies near the desert, and Sardinia in south Italy, which lies near the coast. The antioxidant potential of freeze-dried specimens from the hexane, ethyl acetate, acetone, methanolic, and aqueous extracts was tested using both electron transfer (ET) methods (i.e., TEAC-ABTS, FRAP, and DPPH) and hydrogen atom transfer (HAT) assay (ORAC-PYR). The metabolic profiles of both the methanolic and aqueous extracts were further investigated by 1 H NMR spectroscopy. We also obtained fixed oils by supercritical fractioned extraction (SFE) with CO 2 . GC and HPLC were then used combined to determine the fatty acids profile. All extracts showed significantly different antioxidant capacities. 1 H NMR spectroscopy showed evidence for the presence of amino acids, organic acids, and carbohydrates. The main fatty acids in the oils were 18:1 n-9, 18:2 n-6, 16:0, and 18:3 n-3. All the results showed a difference in chemical composition that influenced the total antioxidant power and the biological activity, verifying that climate affects the chemical composition of plants.

“…De acuerdo con Kuijt (1969) y Musselman & Press (1995), hay unas 3000 especies de plantas parásitas, que representan aproximadamente el 1% de las plantas con flores. Estudios actuales elevan este número a 4423 especies, repartidas en 277 géneros (Nickrent & Musselman, 2004;Jørgensen, 2008).…”

(Balanophoraceae) y efecto de su parasitismo en la anatomía de las raíces de su hospedante Anadenanthera colubrina var. cebil. Anales Jard. Bot. Madrid 73(2): e039.El objetivo de este trabajo fue estudiar la estructura del cuerpo vegetativo de Lophophytum mirabile subsp. bolivianum (Wedd.) B. Hansen, analizar en qué grado se modifican las raíces de Anadenanthera colubrina var. cebil (Griseb.) Altschul cuando son infectadas y determinar los cambios anatómi-cos producidos por este parasitismo. Las plantas de L. mirabile subsp. bolivianum tienen un cuerpo vegetativo subterráneo o túber de forma esferoidal ahusada, que externamente es de un color castaño oscuro a negro y superficie verrugosa; carece de epidermis, estomas o tricomas. La matriz central del túber está compuesta por parénquima de reserva y abundantes haces colaterales dispersos. Las células del parásito ubicadas a nivel del cámbium de la raíz inician la formación de túberes, que surgen como exófitos del cuerpo del hospedante. En el leño de la raíz de A. colubrina var. cebil infectado por el parásito se pierde la identidad del sistema radial y axial del crecimiento secundario. Esto lleva a la formación de bucles de xilema que afectan el transporte y el desarrollo de la raíz, que detiene su crecimiento en longitud y desarrolla una agalla leñosa. La infección de L. mirabile subsp. bolivianum es causa de profundos cambios anatómicos en el desarrollo de la madera de A. colubrina var. cebil que favorecen el éxito del parásito.Palabras clave: agallas, anatomía, leño, parasitismo, raíz. Hansen, to analyze the change on roots of Anadenanthera colubrina var. cebil (Griseb.) Altschul when they are infected by this parasitic plant, and to identify the anatomical changes produced by that parasitism. L. mirabile subsp. bolivianum plants are formed by a spheroidalnarrower underground vegetative body or tuber, that externally has a dark warty surface;epidermis, stomata or trichomes are lacking. The central matrix of tuber consists of reserving parenchyma and vascular bundles. Parasitic cells located at the level of root cambium initiate the tuber formation. On the infected root of A. colubrina var. cebil, the identity of radial and axial growth of the secondary system are lost. This leads to the formation of xylem loops that affect the xylem transport and root development, which stops length growth and develops a woody gall. Infection of L. mirabile subsp. bolivianum causes profound anatomical changes in timber developing of A. colubrina var. cebil, which favor the parasite success.
