Abstract

Recently,Secang had productive be a kind of tea and sold broadly. In Dr. Ratu Safitri research had been known that Secang had antioxidant activity and power as radical scavenging bul they werelabile if extracted ill water.The purpose of tiJis research is to know effect of temperature and time of Secang tea extraction and optimum conditions. In this research, secang teawas extracted in water. The temperature of extraction was varleclof 50' C, 750'C & 100' C and time of extraction was varied of 1, 3 & 5 minutes. Then extract was analyzed with Radical Scavenging DPPH  (1,1-diphenyl-2-picrylhydrazyl) method. The result of this research snowed that increase of temperature and time of secang tea extraction  caused yield  of extract increasingly. Time caused increasing absorbance  of  extraction  but  temperature  was opposite.  The optimum  conditions of secang tea extraction is 50'C and 5  minutes
