Solubility of Nutraceutical Compounds in Generally Recognized as Safe Solvents at 298 K

Remil Aguda and Chau-Chyun Chen
Abstract—The solubility of two model nutraceuticals, quercetin and sclareol, were measured in organic solvents at 298 K by UV-Vis spectrophotometry and gas chromatography, respectively. Thermodynamic models for solid-liquid phase equilibria are used to correlate and predict the solubility of quercetin and sclareol in organic solvents which are Generally Recognized as Safe by the United States Food and Drug Administration. For both quercetin and sclareol, the NRTL-SAC model satisfactorily correlates the experimental data while the COSMO-SAC solubility prediction results are off by more than one natural logarithm of mole fraction of the experimental data.

Index Terms—Generally recognized as safe solvents nutraceutical, NRTL-SAC, quercetin, sclareol, solubility, COSMO-SAC.
