Journal of Chemical & Engineering Data (Impact Factor: 2.05). 02/2008; 53(3). DOI: 10.1021/je700633w

ABSTRACT The solubility of gallic acid in methanol, ethanol, water, and ethyl acetate was measured at a temperature range of (298.2 to 333.2) K. The gallic acid solubility in different solvents increases smoothly with temperature. The relative solubility of gallic acid in the solvents was found as: wmethanol > wethanol > wwater > wethyl acetate. The temperature dependence of the solubility data was correlated by the modified Apelblat model. The calculated solubilities show good agreement with the experimental data in the temperature range studied.

    ABSTRACT: The substitution of large spectrum antibiotics for natural bioactive molecules (especially polyphenolics) for the treatment of wound infections has come into prominence in the pharmaceutical industry. However, the use of such molecules depends on their stability during environmental stress and on their ability to reach the action site without losing biological properties. The application of cyclodextrins as a vehicle for polyphenolics protection has been documented and appears to enhance the properties of bioactive molecules. Therefore, the encapsulation of gallic acid, an antibacterial agent with low stability, by β-cyclodextrin, (2-hydroxy) propyl-β-cyclodextrin and methyl-β-cyclodextrin, was investigated. Encapsulation by β-cyclodextrin was confirmed for pH 3 and 5, with similar stability parameters. The (2-hydroxy) propyl-β-cyclodextrin and methyl-β-cyclodextrin interactions with gallic acid were only confirmed at pH 3. Among the three cyclodextrins, better gallic acid encapsulation were observed for (2-hydroxy) propyl-β-cyclodextrin, followed by β-cyclodextrin and methyl-β-cyclodextrin. The effect of cyclodextrin encapsulation on the gallic acid antibacterial activity was also analysed. The antibacterial activity of the inclusion complexes was investigated here for the first time. According to the results, encapsulation of gallic acid by (2-hydroxy) propyl-β-cyclodextrin seems to be a viable option for the treatment of skin and soft tissue infections, since this inclusion complex has good stability and antibacterial activity.

    ABSTRACT: Natural products play a vital role in the discovery of leads for novel pharmacologically active drugs. Geraniin (GE) was identified as the major compound in the rind of Nephelium lappaceum L. (Sapindaceae), while ellagic and gallic acids have been shown to be its main metabolites. GE and its metabolites possess a range of bioactive properties including being an anti-infective, anticarcinogenic, antihyperglycemic, and antihypertensive. GE and its metabolites were investigated to establish its gastrointestinal absorption and physicochemical properties. GE was purified from N. lappaceum rind extract using reverse-phase C18 column chromatography. Lipophilicity (log P) was determined using the 1-octanol/water shake-flask method. Equilibrium solubility of GE and its metabolites (20 mg) was determined in water and four biorelevant media: simulated gastric, simulated intestinal, fasted state-simulated intestinal, and fed state-simulated intestinal after 72 h. The purification yield was 10.8%; where a 97-99% pure GE was obtained. Log P values for GE, ellagic, and gallic acids were established as -0.73 ± 0.17, 0.11 ± 0.06, and 0.71 ± 0.21, respectively, establishing them as polar compounds. All three compounds were found to exhibit poor solubility in gastric (0.61-8.10 mg/mL) but good solubility in intestinal fluids (3.59-14.32 mg/mL). The above results indicate that the compounds have limited gastrointestinal absorption due to its polarities. To consider these compounds as oral drug candidates, formulation strategies are being developed.

    ABSTRACT: The solubility of gallic acid in (water + ethanol) binary solvents was determined from (293.15 to 318.15) K at atmospheric pressure using a thermostatted reactor and UV/vis spectrophotometer analysis. The effects of binary solvents composition and temperature on the solubility were discussed. It was found that gallic acid solubility in (water + ethanol) mixed solvents presents a maximum-solubility effect. Two empirical equations were proposed to correlate the solubility data. The calculated solubilities show good agreement with the experimental data within the studied temperature range. Using the experimentally measured solubilities, the thermodynamic properties of dissolution of the gallic acid such as Gibbs energy (Delta(sol)G degrees), molar enthalpy of dissolution (Delta H-sol degrees), and molar entropy of dissolution (Delta S-sol degrees) were calculated.
