Calliandra surinamensis or Pinkpowder puff is a tropical shrub, named after Suriname. In Borneo, such as Sarawak and East Kalimantan area, it was known as ‘daun assam jawa’. This species belonging to the family of Leguminosae and subfamily of Mimosoideae originated from tropical America. Calliandra surinamensis has been used in folk medicine to treat various diseases and infections such as cough, wound healing and inflammation. In this study, the flowers of Calliandra surinamensis was extracted by successive extraction. The phytochemical procedures adopted were vacuum liquid chromatography (VLC), and radial chromatography (RC). Phytochemical investigation of Calliandra surinamensis flower afforded three flavonol glycosides identified namely (1) 3-O-rhamnosylkaempferol (2) 3-O-rhamnosylmyricetin and (3) Myricetin-3-O-heptoseptanoside. The molecular structures of the isolated compounds were established based on spectroscopic methods such as 1D-NMR (1H, 13C, DEPT) and 2D-NMR (COSY, HMQC, HMBC) and comparison with literature. © 2016, Malaysian Society of Analytical Sciences.
