Mildbraedin, a novel kaempferol tetraglycoside from the tropical forest legume Mildbraediodendron excelsum

Leaves of Mildbraediodendron excelsum (Leguminosae: tribe Swartzieae) yielded a novel flavonol glycoside characterized by an O-linked branched tetrasaccharide. The same compound was detected by LC-UV-MS as the major component of leaf material sourced from a historic collection of this species made in Cameroon in 1928.
