The aim of the investigation was to determine the antimicrobial activity of the Erythroxylum novogranatense var. truxillense extract against teeth caries bacteria related, which are Streptococus mutans and Lactobacillus casei. Through an alcoholic oxidation technique, filtered and vapored at 40 ˚C, it was obtained the main actives components of Erythroxylum novogranatense var. truxillense. Sterilized water was used as negative control, and 96˚ alcohol as the positive one. The disk diffusion method was performed to test antimicrobial activity. The following results were obtained during the performance of the sensibility tests: For S. mutans there was an average inhibiting halo of 34.4mm±2.12mm, and 33.7mm±3.40mm for L. casei. For control inhibition halos (positive and negative) there was an 00 mm in distilled water and 11.4mm±2.12mm for 96° alcohol. This research was made with a 95% of statistics confidence and significant differences were found. Key words: Coca, antimicrobial effect, Erythroxylum novogranatense var. truxillens, Streptococcus mutans, Lactobacillus casei.
