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.
对木棉干燥叶片70%乙醇提取物的正丁醇部分进行反复柱色谱分离，得到了一种氧杂蒽酮类化合物芒果苷。通过紫外光谱、¹H-核磁共振光谱、¹³C-核磁共振光谱和电喷雾质谱对芒果苷进行了鉴定。结果发现它与沙米明相同，沙米明最初被认为具有黄酮醇结构，但其结构需要修正。
