ABSTRACT

Keladi Tikus plant can be used as a herbal medicine that is the leaves and tubers. Keladi Tikus
is believed to cure various diseases, especially cancer. Keladi Tikus contain ribosome inacting protein
(RIP), antioxidants and substances antikurkumin (Yayat, 2008). Presumably this is an antioxidant
compound that causes taro potential in curing mice of cancer. In research conducted solvent extraction
of ethyl acetate, ethanol and hexane to obtain the yield and antioxidant activity test. To determine the
stability of antioxidants is heating, irradiation and oxidation of design used randomized block design
(RAK) factorial. Research results indicate that the water content of tubers of taro flour rat that is
10.74%. Sucrose content 0.38% hexane, ethyl acetate extract 0.65% and 1.63% ethanol extract.
Taro extract the most active mice obtained from the ethanol extract and its active compounds are
flavonoids. Old heating, sunshine and light significantly affected the stability of antioxidant activity.
The highest damage occurred in pengeruh pemaasan and then the sun light is very small while the
effect on antioxidant activity declined.

Key words : keladi tikus, extraction, stability antioxidants
