Secondary Metabolites of Miconia rubiginosa
MetadataShow full item record
The Miconia genus is the most representative of the Melastomataceae family, and some species are commonly used in Brazilian folk medicine as anti-inflammatory agents. In this work we investigated the leaves from Miconia rubiginosa (Bonpl.) DC, using high-speed countercurrent chromatography, which yielded 11 substances (eight flavonoids, gallic acid, casuarictin, and schizandriside). Identification was achieved using nuclear magnetic resonance spectroscopy and high-performance liquid chromatography-circular dichroism-diode array detection analyses.
