-- The current monography have been purposed to determine chemical compounds by qualitative tests, as well as Antibacterial, antifungical and antioxidant activity of Tagetes elliptica Smith “chincho” leaves essential oil, from Huaraz, Ancash Department. The Tagetes elliptica Smith “chincho” leaves essential oil was obtained by Steam distillation. These essential oils were undergone to Physical-Chemistry analyses, as well as a Spectrophotometry Test by Mass Spectometry joint to Gas Chromatography. By means of Agar diffusion method and Agar dilution method, antimicrobial activity and Minimum inhibitory concentration (MIC) was determined respectively, against the following microorganisms: S. aureus ATCC 25933, S. epidermidis (clinical strain), B. subtilis (environmental strain), E. coli (clinical strain), P. aeruginosa ATCC 27853, Klebsiella (clinical strain) y C. albicans ATCC 10231. From conducted assays, the essential oil showed an antibacterial activity against 5 strains, Klebsiella showed resistance in front of essential oil, due to present an inhibition zone less than 18 mm. In Candida albicans ATCC 10231, the essential oil showed a significant antifungical activity. Minimum inhibitory concentration of Tagetes elliptica Smith essential oil, which has showed consistent activity against S. aureus, E. coli, P. aeruginosa was 7.62 x 10-1 μg/mL; S. epidermidis was 97.5 μg/mL; B. subtilis was 390 μg/mL; and C. albicans was 780 μg/mL. For Antioxidant activity, Two free radicals scavenging assays have been performanced: DPPH activity and Superoxid radical activity; detting the following results: IC50=975μg/mL and IC50= 47.5 μg/mL, respectively; which have not been significant, considering Trolox and Vitamin C standards, respectively. -- Key Word: Tagetes elliptica, essential oils, antimicrobial activity, antioxidant activity.
