A method for the determination of curcumol in the volatile oil of Gurcuma aromatica by thin-layer chromatography coupled with infrared spectrophotometry is reported. The volatile oil is chromatographed on a silica gel G plate with petroleum ether (30~60℃)-acetone (96:4) as the developer. Under this condition, interfering substances with lower polarity than curcumol-are carried farther from the origin while curcumol is retained near the origin. The curcumol zone, which can be ascertained by its predetermined...

A method for the determination of curcumol in the volatile oil of Gurcuma aromatica by thin-layer chromatography coupled with infrared spectrophotometry is reported. The volatile oil is chromatographed on a silica gel G plate with petroleum ether (30~60℃)-acetone (96:4) as the developer. Under this condition, interfering substances with lower polarity than curcumol-are carried farther from the origin while curcumol is retained near the origin. The curcumol zone, which can be ascertained by its predetermined R_f value, is scraped off from the plate and eluted with CHCl_3. For the quantitative determination of curcumol by infrared spectophotometry, use is made of the absorption peak of vinylidene group in the molecule(out-of-plane bending vibration, 890 cm~(-1), 11.24μm) with GCl_4 as the solvent. Since the vinylidene band is specific for curcumol, a complete separation of curcumol from other non-interfering components. is not required. The method is simple and gives accurate and reproducible results. The statistical results show that the average relative deviation of eight determinations is less. than 2%.

In this paper, a linear regression method of multiwavelength data is proposed. The method, based on the difference of molar absorptivity between two coloured chelates at murti-wavelengths, can be applied to simultaneous speotrophotometric determination of two-interfering-component systems in the visible region. As an example, the availability as well as the optimum condition for simultaneous determination of Mn and Zn with 5-Br-PADAP in the presence of nonionic surfactant Triton X-100 have been studied. Measure the absorbance at 15 wavelengths over the range of 540~584 nm and treat the data with the suggested method, the linear correlation coefficients(γ) are found to be 0.998 in the synthetic mixtures containing microamounts of Mn and Zn with the concentration ratio from 1:10 to 10:1. The recoveries of both elements are 95~120% with the relative standard deviations(N=5) less than 17%. The method has been successfully used for direct determination of Mn and Zn in tap water. The new method proposed in this work is simple, fast and can be used for the analysis of two-interfering-oomponen systems.
