ACEITES ESCENCIALES
Previously proven the antioxidant activity of the oils from the Amazon region plants, Mauritua flexuosa (Morete) Plukenetia volubilis
(Sacha inchi) and Oenocarpus bataua (Ungurahua) we elaborated cosmetic creams. The basic emulsions, were formulated avoiding
the use of too many ingredients, which could interfere withthe cosmetic formulation (antioxidant potential of the oils). The samples
were evaluated in a non-invasive study ïn vivo", using as sample 30 women who had some degree of photoaging. We pursued a
dermatologic clinical evaluation and an instrumental evaluation using the MPA Cutometer 580, to visualize the changes in the skin
elasticity and firmness. Evaluations were done before creams application (time = 0 days) and after four weeks of using the products
(time = 28 days), and we performed the respective analysis of variance. The results of the study demonstrated that after 28 days
of treatment, the creams improved the facial skin condition, according to the clinical evaluations creams significantly improve the
brightness and smoothness of skin, and instrumental evaluations indicated an improvement in the firmness and elasticity of the skin.

AGROSISTEMAS
DISTRITO METROPOLITANO DE QUITO
This document displays information regarding the presence, structure and dynamics of agricultural-systems of Quito’s Metropolitan
District (DMQ) and its evolution in the last decades. Some of the changes in the evolution could be occurring in response to the
demographic growth and to the global warming effects.
The global warming effects on this socio economical sector are certainly gradual and they are subject to some degree of uncertainty
due to climate variability (short term) and the Global Warming itself (mid-term). Those changes could be related directly to
the weather, for example to the alterations on the annual rainfall patterns, but also indirectly. The changes occurring in agricultural
systems and its productivity are visible only over several years of study.
Unfortunately, agricultural systems and its activity have not been studied and characterized in detail in the DMQ. The local
government and universities have not considered these kind of studies as priorities. As a matter of fact, the evaluation of the impact
caused by Global warming directly and indirectly on this socio-economical sector is still incomplete, principally due to the lack of
information concerning the dynamics of local agrosystems.
With the currently available information, it is possible to demonstrated that this productive sector is quite sensitive [mid-term] to
the increase of the average temperature and to the increased on frequency and intensity of extreme events (extended droughts during
dry seasons, rainfall increasing and floods during rainy seasons, as well as the decreasing of irrigation with water from glaciers).

ESTUDIO ETNOBOTÁNICO DEL MORTIÑO (Vaccinium floribundum) COMO ALIMENTO ANCESTRAL Y POTENCIAL ALIMENTO FUNCIONAL

MORTIÑO
VACCINIUM FLORIBUNDUM
CAPACIDAD ANTIOXIDANTE
Mortiño is a native wild plant from Ecuador and Colombia. With an edible and tasty berry, mortiño has been consumed since prehispanic
ages with a ceremonial significance that is reflected nowadays in the celebration of Día de los difuntos (All Souls’ day). The
relevant properties are the high content of polyphenols due to the presence of sugars, fibers, lipids,minerals, vitamins proanthocyanidins,
anthocyanidins and flavonoids that permits their use as food colorants. Compounds as flavonoids, tannins and poli-polyphenic
acids are recognized as antioxidants and promote the retinal and general micro circulation, platelet antiaggregation as well as the
reduction of chronic venous insufficiency, potentially suggesting mortiño as a nutritional supplement.

The present study aims to determine the effects of climate change in the weather variability in the Metropolitan District of Quito
and its surroundings in the last 30 years. For this purpose, using data from the National Institute of Meteorology and Hydrology
(Instituto Nacional de Meteorología e Hidrología - INAMHI), two statistical treatmentswere performed. First, a trend analysis of the
maximum and minimum monthly temperatures, precipitation, heliophany, relative humidity and cloudiness using a standard least
squares linear regression method and its associated F-test to determine the statistical significance of the model was done. The second
treatment, looking for extreme events, we analyzed daily data in order to determine temperature and precipitation extremes using
RclimDex package following the ECTCCDI (Expert Team on Climate Change Detection and Indices) recommendations. The results shows
increases in trends and anomalous behavior that may be considered as a result of the effect of climate change and climate variability.
