    Estimación de la huella de carbono para una hectárea cultivada con caña de azúcar desde una perspectiva orgánica
    (Universidad Icesi, 2013-12-13) Ballesteros Meneses, Katherine; Sierra Ruiz, Beatriz Eugenia; Asesor
    Global warming is a problem that today affects humanity, as the average temperature of the planet has been gradually ascending due to increasing concentrations of greenhouse gases (GHG). One cause is air pollution by human or anthropogenic activities present in industrial processes such as energy use, agriculture and the amount of waste. There is growing international evidence on the effects of human activity on the changes of climate change, which leads to policies that governments implement mitigation, adaptation of economic and productive activities. Thus the need to quantify GHG emissions of a product, activity or enterprise is created and the carbon footprint is a concept for the contribution of organizations to be environmentally responsible organizations and be an element of awareness among citizens make more sustainable practices

    Isolation, structural elucidation and cytotoxic activity of tricin, a natural occurring flavone from CaucaŽs Valley sugarcane.
    (Universidad Icesi, 2013-01-01) Ramírez Rivera, Yesid Andrés; Montoya Peláez, Guillermo León; Asesor Tesis
    The Sugarcane can be considered as the most representative crop in the Cauca Valley region southeast of Colombia. The metabolic diversity of this plant makes it suitable as input for several industrial processes, such as ethanol and sugar production. Thus, sugarcane industry is one of the pillars of the local economy. The study and identification of metabolites present in sugarcane opens a new perspective towards the development of new products with potential pharmaceutical and nutritional value. Through the optimization of the sugarcane exploitation, the CaucaŽs Valley economic development would be enhanced. Previous studies have shown that sugar cane is a potential source of flavonoids, mainly in the C-glycoside form1-5. These compounds have special value inside the food and pharmaceutical industries because of their antioxidant properties. The main objective of this project is to achieve the structural determination of some of these metabolites produced by the CaucaŽs Valley sugarcane, by using Nuclear Magnetic Resonance and LC-MS spectrometry. The study resulted in the full characterization of tricin, a natural occurring flavone which is regarded as a potential therapeutical agent for colorectal cancer treatment.
