Abstract

Temulawak (Curcuma xanthorrhiza Roxb) is one of the plants originates from Indonesia. An active component so-called curcumin is considered as an antioxidant. This study was aimed to analyze the curcumin and antioxidant activity of temulawak extract in two different regions. Nine-month-old temulawak rhizomes originated from 2 places named Bener Purworejo, and Tembalang Semarang were applicated. The liquid-liquid extraction method was used. Curcumin level and antioxidant activity were assessed by spectrophotometry and DPPH, respectively. Collected data were analyzed by SPSS software and were presented in narrative form. The level of curcumin in temulawak extract from Bener Purworejo (34,06±0,10%) was slightly higher compared with the curcumin level in temulawak extract from Tembalang Semarang (34,02±0,10%). Furthermore, the antioxidant activity of temulawak extract from Bener Purworejo also was a little higher (91.02±3.41 ppm) compared with the antioxidant of temulawak extract from Tembalang Semarang (94.64±4.74 ppm). In conclusion, there is no different curcumin level and antioxidant activity between temulawak extract from Bener Purworejo and temulawak extract from Tembalang Semarang‎.
