Objective: To evaluate the in vitro antibacterial effect of methanolic extract of Lepidium meyenii in its three ecotypes (red, yellow and black maca) against Streptococcus mutans (ATCC 25175) and Streptococcus sanguinis (ATCC 10556). Materials and Methods: This in vitro study used wells embedded in methanolic extract of Lepidium meyenii in its three ecotypes, placed on 7 petri discs containing the bacteria samples. The Minimum inhibitory concentration (MIC) was evaluated using the Kirby Bauer technique and the minimum bactericidal concentration (MBC) using the colony forming unit (CFU). Inhibition halos were measured in mm and analyzed using descriptive statistics and standard deviation. Results: Against Streptococcus mutans (ATCC 25175), the red maca had a mean result (±sd) of 13.5±0.60 mm, 125.0ug/ml MIC and 62.5ug/ml MBC; the black maca was 13.3±0.53 mm, 125.0ug/ml MIC and 62.5 ug/ml MBC; and the yellow maca was 12±0.27 mm, 250.0 ug/ml and 125.0 ug/ml, respectively. Against Streptococcus sanguinis (ATCC 10556), the mean (±d.e) of the red maca was 17.6±0.23 mm, 62.5ug/ml MIC and 31.3 ug/ml MBC; the black maca was 19.6±0.44 mm, 62.5ug/ml MIC and 31.3 ug/ml MBC, and the yellow maca was 14.8±0.26 mm, 31.3 ug/ml and 15.6 ug/ml, respectively. Conclusion: Exists an antibacterial effect of methanolic extract of Lepidium meyenii in its three ecotypes against Streptococcus mutans (ATCC 25175) and Streptococcus sanguinis (ATCC 10556).
