Description:

4-O-Galloylbergenin shows significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging activity with EC₅₀ 7.8 uM, it shows more antioxidant activity than the positive control vitamin C (EC₅₀ = 28.3 uM).

In vitro:

Nat Prod Res. 2013;27(14):1242-5

A new bergenin derivative from the rhizome of Ardisia gigantifolia.[Pubmed: 22991954]

METHODS AND RESULTS:
One new bergenin derivative, named 11-O-veratroylbergenin (1) along with five known bergenin derivatives, 11-O-(3'-O-methylgalloyl) bergenin (2), 11-O-syringylbergenin (3), 11-O-Galloylbergenin (4), 4-O-Galloylbergenin (5) and bergenin (6) were isolated from Ardisia gigantifolia Stapf. Their structures were established on the basis of spectroscopic analysis, especially by means of 1D, 2D-NMR and HR-ESIMS analyses.
CONCLUSIONS:
Compounds 2, 4 and 5 showed significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging activity with EC₅₀ 9.7, 9.0 and 7.8 μmol L(-1), respectively. They showed more antioxidant activity than the positive control vitamin C (EC₅₀ = 28.3 μmol L(-1)).
