Characterization of cyclotides Mra30 and cycloviolacin O17 derived from Viola dalatensis Gadnep.

Bacteria threaten human and animal health, and standard antibiotics no longer effective. Antibiotic-resistant microorganisms can make infection treatment challenging and perhaps fail. Investigating the attributes of cyclotide, a peptide with promising antibacterial properties that holds great potential in the field of antibiotic research.

A study on the antioxidant, anti-inflammatory, and xanthine oxidase inhibitory activity of the Artemisia vulgaris L. extract and its fractions.

Ethnopharmacological Relevance: Vietnamese people use mugwort (Artemisia vulgaris L.) to treat arthritis and gout. Our previous research shows that mugwort contains flavonoids, and its extract possesses antibacterial and anti-inflammatory activities.

A new triterpenoid and other compounds from lichens Makhija & Patw.

Ten compounds () were purified from the extract of lichens , and among these one new triterpenoid, cryptothecin A () was characterized through mass spectrometric and 2D NMR spectroscopic analyses. Some of the isolated compounds were assessed for their antimicrobial (, , and ) and cytotoxic activity (, , and ), but only weak inhibitory effects were observed.
