Biological Activities
Compounds
Conditions
Ipomoea alba contains an extract identified as EB1493 that demonstrates strong activity against the bacterium Streptococcus mutans. In microdilution broth assays, this specific extract exhibited a minimal inhibitory concentration between 0.08 mg/mL and 0.16 mg/mL. The research further confirmed its effectiveness by determining a minimal bactericidal concentration of 0.16 mg/mL. This potent antibacterial action highlights the plant's potential for developing new chemical agents to prevent dental caries. Such properties position Ipomoea alba as a significant natural resource for treating Streptococcus mutans.
Preparations
Ipomoea alba is prepared as the specific plant extract identified as EB1493 within this study. This particular extract was isolated from the plant to test its effectiveness against Streptococcus mutans. During the microdilution broth assay, EB1493 demonstrated strong antibacterial activity with a minimal inhibitory concentration between 0.08 and 0.16 mg/mL. The research highlights this specific preparation as a significant finding among thousands of screened Amazonian extracts. Consequently, the preparation of Ipomoea alba into EB1493 serves as a potential source for new chemical agents in dental caries prevention.
