Raspberry ketone glucoside (RKG), a natural product in raspberry fruit, is an antioxidant that has the inhibitory effect on the melanin synthesis. It is frequently used in products such as soft drinks, sweets, puddings and ice creams. Interestingly, the solubility of pranlukast hemihydrate increases with a decrease in dielectric constant of the primary alcohols. On the whole, the solubility of 1,3-diphenylguanidine in these solvents followed the order: acetone > ethyl acetate > n-butanol > n-propanol > ethanol > i-butanol > acetonitrile > isopropanol > toluene. For pure solvents, the solubility of acetylpyrazine increases with increasing temperature and solvent polarity. The Apelblat equation provided better results than the other three models. Phyteq™ raspberry I by Ashland Specialty Chemical functions as preservative potentiator that protects the cosmetic against spoilage. Raspberry ketone (1, 10, 20, and 50 μM) suppresses adipogenesis and lipid accumulation in 3T3-L1 pre-adipocytes. The recommended intake is between 100 to 1 400 mg per day. In addition, thermodynamic analysis indicated an endothermic and spontaneous dissolution behavior of pranlukast hemihydrate in the studied solvents. In addition, the change of dissolution enthalpy was the main contributor to the positive value of the molar Gibbs energy of the dissolution process. The models provided a very good correlation of the experimental values in most cases. Finally, the dissolution enthalpy, the dissolution entropy and the molar Gibbs energy were predicted.

With a little digging though, I was able to find some good information on Raspberry ketones. https://doi.org/10.1016/j.molliq.2017.09.084. specification data sheet. The positive values of ΔsolGo, ΔsolHo and ΔsolSo indicate that these dissolution processes of sorbic acid in the solvents studied were all endothermic and entropically favorable. The solubilities of acetylpyrazine in seven pure solvents and one binary solvent mixture were determined by a dynamic analytic method at temperatures ranging from 268.15 to 308.15 K under atmospheric pressure. What are raspberry ketones and do they work? The Akaike’s Information Criterion (AIC) was used to choose the best model for correlating the solubility of OTBNBr. Raspberry ketone is a natural phenolic compound that is the primary aroma compound of red raspberries. The results of the error analysis indicated that the modified Apelblat equation was able to give more accurate and reliable predictions of solubility with the relative average deviation (RAD) and root-mean-square deviation (RMSD) values being observed in the range of 0.21-0.67% and 0.01-0.13%, respectively. It is found in a variety of fruits including raspberries, blackberries and cranberries, and is used in perfumery and cosmetics. The solubility of OTBNBr was correlated by the modified Apelblat equation, the van’t Hoff equation, and the CNIBS/R-K model. The measured solubility data of pranlukast hemihydrate correlated well with the modified Apelblat equation. The onset fusion point temperature and enthalpy of fusion were determined by differential scanning calorimetry (DSC). All content in this area was uploaded by Liang Zhu on Jun 14, 2018. The preferred model is the modified Apelblat equation which has the lowest AIC value. The experimental solubilities of DMHF were correlated with the modified Apelblat equation, van't Hoff equation, λh equation and Combined Nearly Ideal Binary Solvent/Redlich–Kister (CNIBS/R–K) model. The enthalpy of fusion and the melting point of metoprolol succinate were determined by differential scanning calorimetry. The solubility of 4’-bromomethyl-2-cyanobiphenyl (OTBNBr) in binary solvent mixtures of {acetone + (ethanol, n-propanol, and n-butanol)} was experimentally determined within the temperature range 278.15 K to 313.15 K by using a gravimetrical method under atmospheric pressure (P = 0.1 MPa). The acquired solubility of 1,3-diphenylguanidine were correlated with the Apelblat equation, equation, Wilson model and NRTL model, and the the corresponding model parameters were obtained. Raspberry ketone shows cardioprotective action against isoproterenol-induced myocardial infarction in rats, and the effects may be due to its PPAR-α agonistic activity. https://pubchem.ncbi.nlm.nih.gov/compound/4- 4-Hydroxyphenyl -2-butanone#section=Experimental-Properties My initial thought is what would one need with Raspberry ketones? The target of this work is to measure and correlate the solubility of Raspberry Ketone, and obtain the thermodynamic parameters simultaneously. In contrast to the complex mixture of other aromas that alter rapidly if the composition of their multiple compounds is not maintained raspberry ketone is the single dominant volatile that defines raspberry aroma . The solubility would be helpful in optimizing the purification process of 1,3-diphenylguanidine on the industrial scale. Investigations of raspberry ketone in quantitative structure-activity relationship (QSAR) models indicated potential cardiotoxic effects and potential effects on reproduction/development. The effects of temperature and co-solvent composition on the solubility data were discussed. At last,Raspberry Ketone… The development of a crystallization process of L-arabinose is highly dependent on the knowledge of the solubility of both saccharides. In UK the pure compound is regarded as novel food requiring authorisation prior to marketing but raspberry ketone is not withdrawn from Internet sites from this country. Recommendation for raspberry ketone acetate usage levels up to: 6.0000 % in the fragrance concentrate. Measurements were performed using the dynamic method coupled with a. Copyright © 2015.

The experimental solubility data of raspberry ketone in six pure solvents (acetone, ethanol, ethyl acetate, n-propyl alcohol, n-butyl alcohol, and distilled water) was correlated by using several commonly used thermodynamic models, including the Apelblat, van’t Hoff and λh equations. The former two models could reach better fitting results with the solubility data, while the 3D model can be comprehensively used to estimate the solubility data in all the ratios of ethanol and water in binary solvent mixtures at random temperature. rise in temperature and the rising mole fraction of ethanol in binary solvent mixtures. Based on the current solubility data, DMHF has been considered as freely soluble in pure ethanol and slightly soluble in distilled water. Quality confirmed by NMR & HPLC. Raspberry ketone is sometimes used in perfumery, in cosmetics, and as a food additive to impart a fruity odor. Clear up … ... solubility . The solubility of Raspberry Ketone both in mono- solvents and mixtures increased as the temperature increased. The deliquescent rules can be acquired by using modified Apelblat equation, van't Hoff equation, λh equation, Wilson model, Non-Random Two Liquid (NRTL) model, Universal Quasi–Chemical (UNIQUAC) Model and modified Jouyban-Acree model.

The experimental solubility of DMHF in pure solvents was well correlated with the modified Apelblat equation, van't Hoff equation and λh equation. Raspberry ketone in food supplements – High intake, few toxicity data – A cause for safety concern? L-arabinose and D-galactose could be released during the hydrolysis process of Arabic gum. Well, if you watch the Dr. Oz Show, you may have heard Dr. Oz call raspberry ketones “The #1 miracle in a bottle to burn your fat.” Since he made that bold statement, I've heard that raspberry ketone supplements are sold so fast that vitamin stores can't keep them on the shelves! The modified Apelblat equation, Wilson model, and non-random two-liquid (NRTL) model were employed to correlate the solubilities of metoprolol succinate in different solvents. The margin of safety (MOS) based on a NOAEL of 280 mg/kg bw/day for lower weight gain in rats is 165 at 100 mg and 12 at 1 400 mg. Tag: raspberry ketone solubility. The experimental data show highly conformance with the calculated data which obtain from all the selected models. The solubility data were correlated with some thermodynamic models, including the modified Apelblat model, λh model, CNIBS/R-K model, and NRTL model. The maximum mole fraction solubility of pranlukast hemihydrate in 1-butanol was observed to be 26.39 × 10− 5 at 323.15 K, followed by that in 1-propanol (9.63 × 10− 5 at 323.15 K), ethanol (6.18 × 10− 5 at 323.15 K), 2-propanol (5.71 × 10− 5 at 323.15 K), and methanol (3.96 × 10− 5 at 323.15 K).
