Abstract

This study has been conducted to produce the standardization of temulawak (Curcuma xanthorrhiza Roxb). Simplicias was one of the harvest-processed forms. The parameters were optimized based on water content and ash content and functional compound (essential oil, xantorizol, oleoresin, curcumin, and curcuminoid). To get temulawak simplicias product with high quality, it has been done the optimization on the stage of drying process. For the dried by the oven, it has been conducted optimization on the drying temperatures of 70 °C, 80 °C and 90 °C. The analysis result shown that the active compound content in the simplicia product indicates that the product of temulawak simplicia with optimum quality has been obtained from the production process by oven drying method using temperature of 80 °C. The temulawak simplicia product contains essential oils, xantorizol, oleoresin, curcumin, and curcuminoid, each by 1.48%, 67.32%, 1.21%, 92.42% and 1.25%. Meanwhile, the temulawak water content and ash content are 5% and 3,16% that achieve in standard applicable of simplicias product. © Published under licence by IOP Publishing Ltd.
