Abstract

Turmeric is one of the potential medicinal plants, apart from being a raw material for medicine, it is also used as a natural dye. Yellow dye (curcumin) is used as a food coloring for humans. Temulawak (Curcuma xanthorriza Robx) can be used as the main medicinal ingredient in supporting the provision of color. The purpose of this study was to determine the best storage time for turmeric and temulawak extracts that could be used as natural dyes based on color intensity and curcumin content. In this study, the manufacture of turmeric and temulawak extracts was carried out using the decoction method. Determination of storage variations for 7 days was carried out on the influence of storage temperature, namely room temperature (30 ), refrigerator temperature (7 ), drying cabinet temperature (32 ). The color absorbance measurement of curcumin content was carried out by visible spectrophotometric method. The results of the absorbance measurement were used to determine the color stability. The color stability of curcumin in the sample at variations in storage time and temperature was determined based on the absorbance represented in the color intensity of the sample. Furthermore, the color stability can be determined based on the curcumin content. The results of this study were obtained, the absorbance intensity test in turmeric was carried out at a wavelength of 425.14 nm with the results of 0.582 (day 1), temulawak had an absorbance of 0.463 (day 1). The color stability test changed on the 4th day at the temperature of the drying cabinet and room temperature, at the temperature of the refrigerator the color remained stable. Temulawak and turmeric extracts as natural dyes can be stored for a long time if stored at refrigerator temperature the color will remain stable.

Abstract

Turmeric (Curcuma longa L.) is one of the plants known by the public as a spice that has many health benefits. Temulawak (Curcuma zanthorrhiza Roxb.) is one of Indonesia's rich spices that has been known for its benefits and properties since time immemorial. Curcumin is a natural chemical compound found in turmeric and ginger. The purpose of this study was to determine the levels of curcumin by using visible spectrophotometric methods from extracts of turmeric and temulawak using water as a solvent with the decoctation method. The extraction method chosen in this study is the decoctation method. Turmeric and temulawak were extracted by weight ratio of turmeric and solvent 1:3 at a temperature of 90ºC for 30 minutes. The results of this decoctation are separated by decantation. In the results of this liquid extract of turmeric and temulawak, a qualitative test of curcumin was determined using the thin layer chromatography (TLC) method with silica gel 60 F254 as stationary phase and chloroform: ethanol: glacial acetic acid (94: 5: 1) as mobile phase. Then the determination of curcumin levels in turmeric and temulawak extracts was carried out quantitatively using the visible spectrophotometric method. The results of the qualitative test using thin layer chromatography (TLC) obtained the value of curcumin Rf 0.54, turmeric extract Rf 0.54, temulawak extract Rf 0.54. The maximum wavelength obtained is 425.14 nm with an absorbance of 0.428. In determining the calibration curve, the regression equation y = 0.14114x-0.00452 is obtained with r = 0.99963. The levels of curcumin obtained using visible spectrophotometric methods are turmeric extract 80,91088± 1,83864 mg/gand temulawak extract 48,81070± 0,75803 mg/g.
