Abstract

Aloe vera is one of herbal plant that being popular progressively. Not be useful only for the beauty of but also for the health of. Through various researches is known the Aloe vera have a lot of worthwhile content. One of them is polysaccharides acemannan. Because of its benefit, it needs the study to dig the existing potency in the Aloe vera. The extraction-precipitation is one of the treatments to isolate the bioactive (acemannan) which is on the Aloe vera. For this process is used 50 cc juice Aloe vera, 200 cc ethanol 96 %, 10 hours for precipitation time and precipitation temperature at 10oC as constant variable. And the independent variable are temperature operate for the precipitation (30°C - 60°C) and handling time (0 minute - 240 minute). There are the decrease of polysaccharide yield along with the increase of stirring temperature and handling time. The significant decrease of polysaccharide yield happens at 45oC and 120 minutes of the handling time.
