Antimicrobial efficacy of Curcuma zedoaria extract as assessed by linear regression compared with commercial mouthrinses

Abstract

The antimicrobial activity of Curcuma zedoaria (Christm) Roscoe extract against some oral microorganisms was compared with the antimicrobial activity of five commercial mouthrinses in order to evaluate the potential of the plant extract to be incorporated into formulas for improving or creating antiseptic activity. The in vitro antimicrobial efficacy of plant extracts and commercial products were evaluated against Streptococcus mutans, Enterococcus faecalis, Staphylococcus aureus and Candida albicans using a linear regression method to evaluate the microbial reduction obtained in function of the exposure time, considering as effectiveness a 99.999% reduction in count of standardized microbial populations within 60 seconds. The results showed that the antimicrobial efficacy of Curcuma zedoaria (Christm) Roscoe extract was similar to that of commercial products, and its incorporation into a mouthrinse could be an alternative for improving the antimicrobial efficacy of the oral product.

“…(Masuda et al 1993). In addition, white turmeric is reported has analgesic, anti-allergic, antiinflammatory, anti-metastasic, anti-oxidant activities, as well as protecting liver function (Ali et al 2004;Dhal et al 2012), and antimicrobial effect (Bugno et al 2007). The essential oil obtained from the plant dried rhizome by steam distillation, demonstrates active antibacterial properties.…”

Phytochemical and Antimicrobial Properties of the Aqueous Ethanolic Extract of Saccharum officinarum (Sugarcane) Bark

“…For a long time, natural products from plants have been used by man in the area of health. The antimicrobial properties of plants have been studied by a number of researches worldwide and many of them have been used as therapeutic alternatives because of their antimicrobial properties (Adriana et al, 2007). Plants generally produce many secondary metabolites which constitute an important source of microbicides, pesticides and many other pharmaceutical drugs (Mahalingam et al, 2011).…”

Antimicrobial activity of the crude ethanol extract fromPimenta pseudocaryophyllus

“…Several authors have studied the antimicrobial activity of essential oils and plant extracts and have found activity against Gram-positive bacteria (Cunico et al, 2004;Zuque et al, 2004;Fernandes et al, 2005;Hernández et al, 2005;Michelin et al, 2005;Yasunaka et al, 2005;Bugno et al, 2007;Oliveira et al, 2007;Nair & Chanda, 2007). The antimicrobial activity against Gram-positive bacteria B. cereus, B. atrophaeus and B. stearothermophilus observed in this study was relevant, since these are spore-forming microorganisms, and can survive under adverse conditions for several years.…”

“…The diversity of compounds found in plant species make these organisms promising sources of new antimicrobial agents, with general or specific effects. These findings have motivated several studies in different parts of the world (Souza et al, 2002;Cunico et al, 2004;Zuque et al, 2004;Hernández et al, 2005;Michelin et al, 2005;Yasunaka et al, 2005;Bugno et al, 2007;Oliveira et al, 2007;Nair & Chanda, 2007).…”
