Abstract: [Objective] The aim of this study was to separate and purify more than two monomeric compounds from the plant of Dipterocarpus alatus Roxb. [Method] After pulverized, sieved and extracted by alcohol, the extractum of Dipterocarpus alatus Roxb was then seperated and purified using the methods of column chromatography, thin layor chromatography (TLC), and High Performance Liquid Chromatography (HPLC).[Results] Three compounds were indentified as below : bergenin, vaticaffinol, and vatalbinoside A.
