MEJIA GALLON, Amanda Inés; CADAVID TORRES, Elizabeth  and  GALLARDO CABRERA, Cecilia. Antiseptic activity of Guadua angustifolia Kunth vinegar. Rev Cubana Plant Med [online]. 2011, vol.16, n.3, pp. 244-252. ISSN 1028-4796.

Introduction: bamboo vinegars are used in the Asian countries for pharmaceutical applications, but the Guadua angustifolia Kunth species has not been similarly researched in this field. The assessment of the antiseptic activity of guadua vinegar would allow moving forward in this direction. Objective: to determine the antiseptic action of guadua vinegar against Pseudomona aeruginosa and Staphylococcus aureus bacteria, with several changes in concentration and the pH. Methods: the antimicrobial activity was measured through the agar diffusion in Muller Hinton medium. Guadua vinegars were tested at 100, 80, 60, 40, and 20 % concentrations and the pH ranged 3 to 6. The minimum inhibitory concentration was set. Results: guadua vinegar showed antiseptic properties at concentrations over 12 mg/mL, on dry weight and pH range of 2 to 6; it reduced by 4 log the final microorganism concentration and exhibited greater antibacterial activity against S. aureus. Conclusions: comparing the antiseptic activity of bamboo vinegar with that of another species, under conditions similar to those in this study, results in greater activity for Guadua angustifolia vinegar, which can prove its great potential for the development of antiseptic formulations.
