Identification
Biological Activities
Compounds
Conditions
Dioscorea cayenensis subsp. cayenensis was not identified in the provided research as having any effect on Streptococcus mutans biofilm. Instead, the study highlights that only extracts from Dioscorea altissima and Annona hypoglauca demonstrated activity in the biofilm assay. While several Brazilian plant extracts inhibited planktonic bacteria, most failed to prevent the organization or disruption of the single-species biofilm. Specifically, the extract EB1779 from Dioscorea altissima was one of only two substances that showed efficacy in this specific model. Therefore, no evidence exists in this text to support the claim that Dioscorea cayenensis subsp. cayenensis treats Streptococcus mutans biofilm.
Preparations
Dioscorea cayenensis subsp. cayenensis is prepared as plant extracts, though the provided abstract focuses on different species. While the study examines extracts from the Brazilian Amazon, it specifically highlights the activity of extracts from Dioscorea altissima and Annona hypoglauca. These prepared extracts were tested for their ability to influence Streptococcus mutans biofilms. The research sought to determine if such plant-derived solutions could prevent or disrupt bacterial organization. Ultimately, the study explores the potential of these natural products for applications in dentistry.
