ABSTRACT - Free (epi) catechin, quercetin, (epi) gallocatechin, flavonol glycosides and condensed tannins were identified according to their molecular mass, characteristic product ions and retention times in extracts obtained from leaves and branches of Maytenus ilicifolia (Congorosa) by mass spectrometry. The in vitro anthelmintic activity against cattle gastrointestinal nematodes of Congorosa extract was determined using the Egg Hatch Inhibition Assay. Additionally, commercial quercetin, gallocatechin and epicatechin were evaluated. Although total phenolics, total tannins and condensed tannins contents were lower in branches extract than in leaves extract, the EC50 were 0.065mg/mL and 0.890 mg/mL for branches and leaves extract, respectively. Moreover, the use of polyvinylpyrrolidone as a blocking agent of tannins, did not change significantly the EC50 for branches extract, but significantly changed for leaves extract. Quercetin and gallocatechin EC50 values were in the range 0.03–0.05 mg/mL and epicatechin showed 100% inhibition of the egg hatching process at 0.004mg/mL.

ABSTRACT.
The massive use of pesticides and herbicides to increment the agriculture production can produce severe environmental impacts. This implies the need of new methods to monitor and control the use of chemical agents.An alternative to traditional sampling methods is the use ofinsects to act as a biological distributed sensor in order to monitor the presence of pesticides in the neighbourhood. Specifically, several authors have proposed the use of the beehive as a distributed sensor. To evaluate critical changes in the beehive behaviour, the sound patterns are analysed. In this work the guidelines used to develop a remote monitoring system in order to detect abnormal changes in the sound patterns in hives are presented. The evolution of the frequency spectrum sampled in four temporal windows is proposed to monitor the beehive health. Experiments to determinate the frequency band and the frequency resolution are presented for the case of Apis mellifera. Using these guidelines a complete monitor system was developed and constructed.
