Therapeutic Potential of Flavonoids and Tannins in Management of Oral Infectious Diseases-A Review.

Medicinal plants are rich sources of valuable molecules with various profitable biological effects, including antimicrobial activity. The advantages of herbal products are their effectiveness, relative safety based on research or extended traditional use, and accessibility without prescription. Extensive and irrational usage of antibiotics since their discovery in 1928 has led to the increasing expiration of their effectiveness due to antibacterial resistance.

Antimicrobial and Antioxidant Properties of Four Taxa and an Interaction Study of Their Major Compounds.

The compositions of leaf infusions of three genotypes of L. with origins in central Europe, namely A (LeuA), B (LeuB), and C (LeuC), and one genotype of (Lex), were examined by LC-MS-DAD (Liquid Chromatography Mass Spectrometry and Diode Array Detection) analysis. This revealed the presence of thirteen compounds belonging to the groups of phenolic acids and flavonoids, with a predominance of rosmarinic acid (RA) and luteolin-7--glucuronide (LGlr).

Rhizomes as an Alternative Source of Natural Antioxidants.

Unlike its aerial parts, the underground parts of have so far been studied only marginally. By examining the polyphenolic fingerprint, the antioxidant efficacy and the mutual antioxidant behaviour of mixtures of mint rhizomes, our study presents a modest contribution to addressing this gap. Firstly, we examined the composition of the mint rhizomes: cv.
