Abstract

LUNA-VILCHEZ, Medalit; DIAZ-VELEZ, Cristian  and  BACA-DEJO, Francisco. Effect of the aqueous, acidic and alcoholic extract of dried leaves of Erythroxylum coca var. coca (coca) in Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum canis and Candida albicans in vitro. Horiz. Med. [online]. 2017, vol.17, n.1, pp.25-30. ISSN 1727-558X.

Objective: To evaluate the effect of the aqueous, acidic and alcoholic extract of dried leaves of Erythroxylum coca var. coca (coca) in Trichophyton rubrum (TR), Trichophyton mentagrophytes (TM), Microsporum canis (MC) and Candida albicans (CA) in vitro. Materials and methods: An experimental study which evaluated the presence or absence of fungal growth, and fungal growth rate from the seeding point, compared to fungal growth in Sabouraud Agar (SA) using Siegel-Tukey and Kruskal- Wallis tests (p<0.05). Results: The CA group showed a statistical difference (p<0.05) between the following groups: 99.9% ethanol vs. aqueous, 99.9% ethanol vs. 0.01M HCl, 99.9% ethanol vs. control, control vs. aqueous, 0.01M HCl vs. control. The TR group showed a statistical difference (p<0.05) between the following groups: 99.9% ethanol vs. 0.01M HCl, 99.9% ethanol vs. aqueous, 99.9% ethanol vs. control, 0.01M HCl vs. control. The TM group showed a statistical difference (p<0.05) between the following groups: 99.9% ethanol vs. 0.01M HCl, 99.9% ethanol vs. control, aqueous vs. acid, aqueous vs. control. The MC group showed a statistical difference (p<0.05) between the following groups: 99.9% ethanol vs. 0.01M HCl, 99.9% ethanol vs. control, aqueous vs. acid, aqueous vs. control. In all the cases, the results of the 0.01M HCl vs. aqueous group were not significant. Conclusions: The aqueous, acidic and alcoholic extracts have no effect on the growth of CA and TM, but the alcoholic extract has effects on the growth of TR and MC. In addition, there were differences in the growth rate of CA, TR and TM in the aqueous, acidic and alcoholic extracts compared to that in SA. However only TR, TM and MC showed differences in their growth rate in the alcoholic extract
