Curcuma longa is a plant that has stood out in research evaluating antimicrobial, anti-inflammatory, antiprotozoal, anticarcinogenic and antifungal activity. The discovery of new alternatives for developing drugs based on active ingredients from plants is necessary considering the high adaptive capacity of different microorganisms. Therefore, the present study aimed to evaluate the antimicrobial activity of oleoresin extracts and suspension of powder from Curcuma longa rhizomes against the bacteria Escherichia coli .
In this study, no antimicrobial activity was observed for turmeric powder and oleoresin extracts against Escherichia coli . In the literature, there is a wide variety of results obtained from tests with C. longa on different microorganisms, some of which are positive, demonstrating antimicrobial action, and others are negative. This divergence is justified by europe mobile number list factors such as: different methodologies used, climate, soil types, fertilization, water availability for plant cultivation, as well as the way of harvesting and storage, which affect the components present and their concentration in the plant. Although the results of this study were negative, it does not mean that the plant does not have antimicrobial activity, and continued testing is recommended, aiming to identify the factors that generate disagreement between the studies already carried out. Keywords: Natural products, Resin oil, Turmeric powder, Curcumin, Antimicrobial activity. 1. INTRODUCTION Natural products have been used throughout history to treat and prevent diseases. Currently, they are gaining great importance in research into the development of drugs of natural origin.
Several groups of researchers have studied the biological activity of medicinal plants originating from different parts of the world, guided by the popular use of native species (SILVA FILHO et al ., 2009; SANTOS et al ., 2021; BANDEIRA et al ., 2022). A plant that, in addition to being used in cooking, has been present in research in pharmacological areas is Curcuma longa L., popularly known as saffron or turmeric. It is a herbaceous plant, belonging to the Zingiberaceae family , native to Southeast Asia, more precisely to the tropical forests of India, the country with the largest production in the world (PEREIRA; STRINGHETA, 1998; FRANCO et al ., 2007; SABIR et al ., 2021).
