Resumen

En el presente trabajo se evaluaron el contenido de flavonoides, las actividades antimicrobianas y antioxidante de los propóleos de abejas sin aguijón, Melipona quadrifasciata check for this species in other resources , Melipona compressipes check for this species in other resources , Tetragonisca angustula check for this species in other resources y Nannotrigona check for this species in other resources sp., mediante el uso del extracto etanólico de propóleos (EEP) contra las bacterias Gram positivas, Staphylococcus aureus check for this species in other resources y Micrococcus luteus check for this species in other resources . El propóleos fue colectado en los estados Miranda y Guárico, Venezuela, y São Paulo, Brasil, durante el período de noviembre de 2003 a abril de 2004. Los contenidos de flavonoides fueron muy bajos, variando de 0,19 a 0,32%. La actividad antioxidante en todas las muestras fue menor a 22 seg, con media de 3 a 5 seg. Los EEP de M. quadrifasciata mostró la mayor actividad antioxidante. Los EEP de todas las muestras tuvieron una elevada actividad antimicrobiana contra Staphylococcus aureus y Micrococcus luteus, con halos de inhibición de 11 a 30 mm, tanto en las muestras de Brasil como en las de Venezuela. El EEP de la Nannotrigona sp. mostraron mayor actividad antimicrobiana que los de otras abejas. Se concluye que los propóleos de las abejas sin aguijón estudiadas poseen elevadas actividades antioxidante y antimicrobianas, aunque los contenidos de flavonoides sean bajos.

Abstract

Flavonoids content, antibacterial and antioxidant activities of Brazilian and Venezuelan propolis from stingless bees, Melipona quadrifasciata check for this species in other resources , Melipona compressipes check for this species in other resources , Tetragonisca angustula check for this species in other resources , and Nannotrigona check for this species in other resources sp. were evaluated using ethanolic extracts of propolis (EEP) against Gram positives bacteria, Staphylococcus aureus check for this species in other resources and Micrococcus luteus check for this species in other resources . The propolis samples were collected in three locations, São Paulo state, Brazil, and Miranda and Guárico states, Venezuela, from November 2003 to April 2004. The results showed that the flavonoid content was very low for all samples, between 0.19 and 0.32%. The antioxidant activity was lower than 22 sec for all samples (3-5 sec of average). The EEP from Melipona quadrifasciata bees showed higher antioxidant activity than the other stingless bees. All EEP showed high antibacterial activity, with an inhibition halo between 11 to 30 mm, against Staphylococcus aureus and Micrococcus luteus, for all Brazilian and Venezuelan samples. EEP from Nannotrigona sp. showed higher antibacterial activity than other bees. The propolis studied showed high antibacterial and antioxidant activity, despite lower flavonoids percentages
