Isolation of mangiferin from Bombax malabaricum and structure revision of shamimin

Planta Med. 2003 Nov;69(11):1068-70. doi: 10.1055/s-2003-45161.

Abstract

Repeated column chromatography of the n-BuOH fraction of the 70% EtOH of the dried leaves of Bombax malabaricum led to the isolation of mangiferin, a xanthone. Mangiferin was identified by UV, 1H- and 13C-NMR spectroscopy and electrospray mass spectrometry. It was found to be identical to shamimin, a compound for which originally a flavonol structure was proposed, and the structure of which has to be revised.
