The objective of the study was to evaluate the composition chemistry of aqueous and alcoholic extract and fresh leaves of Tagetes elliptica Sm. ethanolic “chincho” and determine the antibacterial and antifungal activity in vitro and its application in an andean food. The plant species was obtained in the town of mills in the province of Jauja in the Region Junín. The summary was obtained by the method of maceration with ethanol of 96°. The chemical composition is determined by the Mass Spectrometer/gas Chromatograph (GC /MS). The determination of the antibacterial and antifungal activity was determined by the method of diffusion in agar, against the strains of the following microorganisms: Staphylococcus aureus ATCC 25933, Bacillus subtilis ATCC 6633 , Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853; also against the yeast Candida albicans ATCC 10231. With the aqueous extract was its application in an andean food. The analysis GC/MS determined the following chemical components: dianthydrodulcitol, ceanothine c, resorcinol, pirocatecol, 2-(2-butynyl)cyclohexanone, -, z, z-6, 24-tritriacontadien-2one, and 5-hexyl-2,4-dimethyl oxazole, Evaluation of antimicrobial and antifungal activity in vitro of the aqueous extract not showed antibacterial activity against S.aureus, B.subtillis, E.coli and P.aeruginosa at any of the concentrations tested of 100, 50 and 25 mg/mL respectively. Ethanolic extract of Tagetes elliptica Sm. “chincho“ showed activity against Staphylococcus aureus ATCC 25933, and Pseudomonas aeruginosa ATCC 27853 worked three concentrations and not having any activity against Bacillus subtilis and Escherichia coli. The activity shown against Staphylococcus aureus and Pseudomonas aeruginosa is not significant, since the concentration of 25 mg/mL, the zone of inhibition presented wasn't more than 18 mm. The antifungal activity of ethanolic and aqueous extract was inactive, the aqueous extract and Tagetes elliptica Sm, ethanolic should its fragrance chemical composition which has its essential oil and antimicrobial activity because of resorcinol and pirocatecol; phenolic compounds that it would endow them antimicrobial activity, dominate aroma and flavor in the andean food integrated into the Andean stew called pachamanca. Key words. Tagetes elliptica Smith, pachamanca, Antibacterial, antifungal.
