This research is telling about estimating amount of coffeine cosumption in energy drink which available in the market with HPLC method. Energy drink filtrat fractionated with chloroform and chloroforom fractionation evaporated by rotary evaporator. Coffein amount measured by HPLC using column LC- 20 AD ( Length 20 cm ) and detector SPD – 20 MAD (λ 272 nm) with mobile phase methanol : water (50:50). Amount estimating of coffein from this research in 1 bottle Sample Kr =27,7264 mg, M =34,140 mg, Pm=28,41 mg and sample Lv= 69,78 mg. The results sample Lv that exceed the limit set by SNI Num. 01-6684-2002 is less than 50 mg.
