Corn silk is a waste of food industries, but traditionally used for diuretic and hypertension. Whereas, research and publication about its chemical compound are limited. The goal of the research is to study chemical compound of corn silk. Crude drugs of corn silk were consequtively extracted with Soxhlet apparatus, using n-hexane, ethyl acetate, and ethanol. Ethyl acetate extract was fractionated by vaccum liquid chromatography. Purification was conducted by preparative thin layer chromatography. Isolate was characterized by specific spray reagent, ultraviolet-visible, and infrared spectrophotometries. Characterization with specific spray reagent AlC13 5 %, FeC13 4,5%, and Liebermann-Burchard showed no color reaction. Ultraviolet-visible spectrum showed two peaks at 290 nm and 367 nm. Infrared spectrum showed the presence of -OH, aliphatic C-H, aromatic C=C, and C=O groups. Isolate was identified as one flavanone with substituted -OH group at atom C number 5 and or 3, 4. <br />
