5-hydroxymetylfurfural (1), bisdehydroneotuberostemonine (2) and a mixture containing neotuberostemonine (3) were isolated from Stemona tuberosa's climbing plant. The chemical structure of these compounds is determined by 1-dimensional and 2- dimensional magnetic resonance spectroscopy methods as well as comparison with references. | Study on isolating and determining the structure of some organic compounds in tubers of stemona tuberosa in Central Highlands of Vietnam
