- W2757031460 abstract "INTISARI Telah dilakukan penelitian tentang penetapan kadar kofein dalam minuman berenergi yang beredar dipasaran secara Kromatografi Cair Kinerja Tinggi. Minuman energi ini difraksinasi dengan kloroform. Hasil fraksi kloroform diuapkan dengan rotary evaporator. Kadar kofein diukur dengan kromatografi cair kinerja tinggi menggunakan kolom LC- 20AD dengan panjang 25 cm dan detektor SPD-20MAD dengan panjang gelombang 272nm. Fase gerak yang digunakan Metanol : Air (50:50)dengan laju alir 1 mL/menit. Dari hasil penelitian didapatkan kadar kofein dalam 1 botol sampel Kr =27,73 mg, M =34,14 mg, , Pm=28,41 mg dan sampel Lv =69,78 mg. Hasil tersebut sampel Lv yang melebihi batas yang telah ditentukan oleh SNI No. 01-6684-2002 yaitu kurang dari 50 mg persaji. Kata Kunci : KCKT (Kromatografi cair kinerja tinggi, Koffein ABSTRACT 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. Keywords: HPLC(high performance liquid chromatography), Coffeine" @default.
