Author(s): Narsih, Agato

The Aloe vera peel extraction of 10minutes at 1150C gave the best effect of its chemical composition. Whilst Aloe vera skin using subcritical water method was obtained fromextracted withwater at 125oC for 60 minutes. It had following properties: mineral content of 20.654 mg/g; protein content of 120.114mg/g; vitaminCcontent of 161.431mg/g; aloin content of 10.251 mg/g; saponin content of 9.71mg/g; total phenolic content of 39.851 mg/g; antioxidant activity of 87.651%. The FTIRanalysis showed thatCHStretch in alkana vibration at 2941.24 cm-1 to 2991.39 cm-1wave was found for the methilene compound as antioxidant agent.
