Fatty acid composition and some physicochemical characteristics of <em>Sterculia apetala</em> seed oils

Grasas y Aceites (2014)

Socorro Herrera‐Meza Armando J. Martínez María Guadalupe Sánchez-Otero Ma. Remedios Mendoza-López Oscar García‐Barradas

In the tropical rain forests of southeastern Mexico, the use of Sterculia mexicana and Sterculia apetala seed oils for human and animal nutrition is common. However, the seeds contain cyclopropene fatty acids, whose consumption is related with beneficial as well as detrimental physiological effects. The aim of this study was to determine the fatty acid profile and the physicochemical characteristics of S. apetala seed oil and to evaluate the effect of roasting on both aspects. Cyclopropenoic fatty acids, sterculic acid and malvalic acid were identified in the natural and roasted seed oils. The major component in the seed oil was sterculic acid, as has been reported for Sterculia mexicana and Sterculia foetida. The roasting process modified some physicochemical properties and the fatty acid composition of the seed oil, particularly by decreasing its content of sterculic acid. To our knowledge, this is the first report on the fatty acid composition of S. apetala seed oil.

Crecimiento de <i>Casuarina equisetifolia</i> (Casuarinaceae) en suelo con diésel, y aplicación de bioestimulación y bioaumentación

Revista de Biología Tropical (2013)

María Esther Díaz Martínez Alejandro Alarcón Ronald Ferrera‐Cerrato Juan José Almaraz-Suárez Oscar García‐Barradas

Phytoremediation is an ecologically sound biotechnology directed to cleaning up contaminated soils. The study of tree species to treat petroleum contaminated soils is scarce; moreover, the combination of phytoremediation with bioaugmentation and biostimulation processes is also limited. Thus, this work evaluated the effects of the inoculation of Glomus intraradices, a bacterial consortium (M2BOS1-R2 and M2BOSI-F4) and Trichoderma viride, on the growth of Casuarina equisetifolia, fertilized with Floranid or Triple 17, when sown in a diesel-contaminated soil (7 500mg/kg). The factorial experiment 2x5x3 included 30 treatments with 10 replicates in a completely randomized design under greenhouse conditions for 120 days. Diesel significantly diminished plant height, total biomass, and plant index quality (PIQ). Glomus or bacterial consortium significantly increased plant height, total biomass and PIQ when compared to the inoculation of the three microorganisms or to the control. Floranid had negative effects on plant growth and PIQ at diesel contamination. Fertilization with Triple 17 combined with the three microorganisms stimulated plant growth in the absence of diesel, whereas in the presence of this contaminant the treatments combining Triple 17 with the bacterial consortium or with Trichoderma had better plant growth and PIQ. Mycorrhizal colonization was inhibited due to diesel contamination, and especially when Floranid was applied. The fertilizer Triple 17 (biostimulation) combined with the beneficial microorganisms (bioaugmentation) improved growth responses of C. equisetifolia in diesel-contaminated soil.

Synthesis of Imidazole Derivatives and Their Biological Activities

Journal of Chemistry and Biochemistry (2014)

Delia Hernández‐Romero Víctor E. Torres Heredia Oscar García‐Barradas Ma. Elizabeth Márquez López Esmeralda Sánchez Pavón

Synthesis of Imidazole Derivatives and Their Biological Activities Delia Hernández Romero, Víctor E. Torres Heredia, Oscar García-Barradas, Ma. Elizabeth Márquez López, Esmeralda Sánchez Pavón Abstract Imidazoles play an important role in medicinal chemistry, because many of its derivatives have demonstrated significant biological activity. This article is a revision of the last years, of the synthesis methods used in the preparation of imidazole derivatives which have shown biological activity as antibacterial, antiinflammatory, analgesic, antifungal, anticancer, antidepressants, including inside the biological activities of different therapeutic diseases.

Uncatalyzed One‐Pot Diastereoselective Synthesis of α‐Amino Phosphonates Under Solvent‐Free Conditions

European Journal of Organic Chemistry (2010)

Gaurao D. Tibhe Selene Lagunas‐Rivera Marı́a Elena Vargas-Dı́az Oscar García‐Barradas Mario Ordóñez

Abstract Uncatalyzed one‐pot, three‐component reactions of aldehydes, chiral α‐methylamines, and dimethyl phosphite under solvent‐free conditions were used for the diastereoselective synthesis of α‐amino phosphonates. The reactions proceeded with extremely high efficiency under mild conditions and gave good yields and diastereoselectivities (70:30 to 93:7 dr ). This approach could be useful for the large‐scale synthesis of several α‐amino phosphonates.

Epicuticular compounds and sexual recognition in the ball‐roller scarab, Canthon cyanellus cyanellus

Entomologia Experimentalis et Applicata (2006)

Maribel Ortíz-domínguez Mario E. Favila Ma. Remedios Mendoza-López Oscar García‐Barradas Jesús Samuel Cruz-Sánchez

Abstract We analyzed the role of cuticular compounds in sexual recognition of the carrion ball‐roller scarab, Canthon cyanellus cyanellus (LeConte) (Coleoptera: Scarabaeidae). Males rolled food balls with freeze‐killed females on them as though the females were alive. Acceptance of female cadavers was low when they were washed with solvents and increased significantly when the solvent extract was reapplied to the cadavers. Acceptance of female cadavers by males was significantly higher than that of male cadavers by females. Male cadavers washed with solvent and impregnated with female cuticular compounds were accepted by males as though they were frozen or living females. Similarly, extracted female cadavers impregnated with male cuticular compounds were accepted by females. These results suggest that C. c. cyanellus males recognize females by their cuticular compounds, whereas females use a combination of cuticular compounds and other unknown cues to recognize males.
