Biological Activities
Compounds
Sempervivum tectorum is a plant species that contains a diverse array of polyphenolic compounds within its fresh leaves. Scientific analysis through acidic hydrolysis has revealed that kaempferol serves as the unique aglycon for the three main oligomeric constituents of the plant. Furthermore, researchers identified delphinidol as the primary anthocyanidin detectable in the material obtained from the polymeric polyphenol fraction. These chemical components are part of a complex structure that also includes potential procyanidins of the B2 type. Ultimately, the presence of these specific substances contributes to the notable antimicrobial activity observed in Sempervivum L. leaves.
Conditions
Sempervivum tectorum exhibits significant antimicrobial activity, particularly through its high phenolic and proanthocyanidin content. The plant's ethanolic extracts have demonstrated the ability to treat infections caused by the Gram-negative bacterium P. aeruginosa. Additionally, it has shown effectiveness in treating the Gram-positive bacterium S. aureus through both bacteriostatic and bactericidal effects. Traditional medicinal uses include the application of the plant to treat ear pains. Historical household remedies also utilized its sap to treat ocular inflammations.
Preparations
Sempervivum tectorum is prepared as sap, which was historically utilized as a household remedy for ocular inflammations. This plant's sap serves as a traditional treatment, similar to how the sap of Aeonium lindleyi is used to remove the caustic effects of Euphorbia cyparissias. Additionally, Sempervivum tectorum is prepared as sliced fresh leaves to facilitate the isolation and assessment of its polyphenols. Through the extraction of these sliced leaves, researchers identified specific oligomeric and polymeric polyphenols, including kaempferol. The study of these leaf preparations also allowed for the observation of antimicrobial activity against various microorganisms.
Parts used
Sempervivum tectorum is a plant species that holds significant biochemical interest due to the unique compounds found within its structure. Researchers have focused their attention on the plant's leaf, which serves as a primary source for isolating various polyphenols. Through detailed extraction processes, scientists identified both oligomeric and polymeric polyphenols, including the aglycon kaempferol. These chemical analyses also revealed the presence of anthocyanidins and potential B2 type procyanidins. Ultimately, the antimicrobial activity of the Sempervivum L. leaves demonstrated effectiveness against a wide range of microorganisms.
