ABSTRACT: Thermophysical properties including densities and viscosities of naringenin in aqueous solutions of ethanol/1-propanol with alcohol concentrations of (24.00 to 40.00) mol·kg−1 have been measured as a function of concentration of naringenin at temperatures from (293.15 to 323.15) K and atmospheric pressure. Also, refractive indices for studied systems have been determined at 298.15 K. The measured data were used to calculate the apparent molar volume (Vϕ), standard partial molar volume (V0ϕ), partial molar volume (V̅ ), viscosity B-coefficients, and molar refractions (Rm). The viscosity and refractive index data have been analyzed by Jones−Dole and Lorentz−Lorenz equations, respectively. The trends of variation of experimental and calculated parameters have been discussed according to the interactions between solvents and solute. The obtained results imply that naringenin acts as a structure maker in the studied system.



INTRODUCTION

As a pharmaceutical drug, it is inevitable to study naringenin’s various interactions in aqueous solutions in order to determine the functional properties of it. There is some information regarding naringenin properties in different solvents solutions;11,12 however, information with respect to the densities, viscosities, and refractive indices of naringenin in aqueous solutions was not found in the relevant literature. Therefore, in the present work, densities and viscosities of naringenin in aqueous ethanol/1-propanol solution at temperatures from (293.15 to 323.15) K and different alcohol concentrations (m = 24.00 to 40.00 mol·kg−1 in water) have been measured. Also, for studied systems refractive indices have been determined at 298.15 K. The measured density data was used to calculate apparent molar volume and standard partial molar volume. Furthermore, measured viscosities and refractive indices data were used to compute the viscosity B-coefficients and molar refractions, respectively. All of the obtained parameters have been used to describe the solute−solvent interactions in the ternary systems. The viscosity and refractive indices data have been analyzed by Jones−Dole and Lorentz−Lorenz equations, respectively. All of the obtained parameters have been used to describe the solute−solvent interactions occurring between the various components in the studied ternary system.

Naringenin (C15H12O5, CAS: 480-41-1), a plant flavonoid, has attracted significant scientific and public interest in Chinese medicine by owning the versatile health-promoting effects of antioxidation,1 antiulcer,2 reducing cholesterol,3 and antiinflammation.4 Knowledge of thermophysical properties of drugs with organic solvents in chemical processes requires reliable and systematic data such as densities and viscosities.5 This information is useful to understand the intermolecular interactions present in liquid pharmaceutical systems.6,7 The intermolecular interactions are commonly connected with noncovalent interactions including hydrophobic interactions, electrostatic interactions, and hydrogen bonding, which are influenced by the surrounding solutes and solvent.8 Volumetric properties provide useful information to solute−solvent interactions. Also, volumetric properties could provide a better introduction to the interactions of the components in solutions. These properties not only depend on solvent−solvent, solute− solvent, and solute−solute interactions, but also the structural effects result in interstitial accommodation due to the difference in molar volume and free volume between components in the system.9 Viscometric properties give important information about solute−solute and solute−solvent interactions and could help us to confirm the results of volumetric properties. Literature survey indicates that, few experimental works have been performed to study thermophysical properties of drugs in different alcohols solutions. In this way, Li et al.10 measured the density and refractive indices of hexane-1,2,3,4,5,6-hexol in aqueous solutions of 1-propanol and 2-propanol, and Chen et al.6 have also studied 7-hydroxy-4-methylcoumarin’s viscometric, volumetric, and refractive index behavior in aqueous ethanol or 1-propanol solutions in different temperature ranges. © 2017 American Chemical Society

The relative standard uncertainties for densities and viscosity are ur (ρ) = 0.005, ur(η) = 0.01, and the standard uncertainty of refractive indices is u(nD) = 0.0005.

Viscosity measurements were carried out with an Anton Paar AMVn at different temperatures. By this apparatus, the working temperature can be controlled within ±0.01 K. The viscometer was calibrated with distilled deionized water before use. The measured data of solutions compared with literature are shown in Table 2. The percentage deviation of viscosities (η) with literature values were ±0.69%. The flow time of the solutions through the whole capillary was recorded, and the following equation was used to calculate the viscosities of the solution.

Ethanol and 1-propanol were purchased from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China). Water obtained by a Millipore, Milli-Q (Bedford, MA, USA) purification system was used to prepare the aqueous solution. The sources and purities of chemicals used in the experiment are listed in Table 1. Apparatus and Procedure. The studied solutions were prepared in glass vials in molal base concentration by mass using an analytical balance (A CP 225D balance (Sartorius, Germany) with an uncertainty of ±0.01 mg to achieve exact molality concentrations (m = 24.00, 28.00, 32.00, 36.00, and 40.00 mol·kg−1) of ethanol/1-propanol in water without a solute and concentrations (m = 0.00, 0.01, 0.02, 0.03, 0.04, and 0.05 mol·kg−1) of naringenin in the mixed solvents. The weight of the solute and solvents in the studied system are given in Table S1. All the solutions were kept in glass bottles with a cap to prevent evaporation before use. Measurements were performed immediately after preparation of solutions. The density data of the solutions at different temperatures were measured using an Anton Paar DMA 5000 M densimeter (with an accuracy of ±0.005 kg·m−3). The apparatus was calibrated with double distilled deionized, and degassed water, and dry air at atmospheric pressure. The measured density data of pure solvent and solutions compared with literature are shown in Table 2; however, there are no available literature data for naringenin. The percentage deviation of density (ρ) with literature values was ±0.17%.

where ρ represents the density of the solution, t represents the flow time of the solution in the capillary. In this work, k was calibrated to be 0.010167 using distilled deionized water at 293.15 K (η = 1.002; ρ = 0.99820). Refractive index values nD of the studied solutions were determined using a WYA-2S refractometer (Shanghai BM Instruments Manufacture Co., Ltd., China) with an uncertainty of 5 × 10−4. The temperature of the solutions was maintained at 298.15 K using a constant temperature thermostatic bath (THD-2006, Ningbo Tianheng Instrument Works Co., Ltd., China) with a thermal stability of ±0.1 K. The measured refractive index value of pure water at 298.15 K was reported in Table 2 and compared with literature value. The percentage deviation of refractive indices (nD) with literature values were ±0.08%. 3230

RESULTS AND DISCUSSION Volumetric Properties. To evaluate volumetric properties and intermolecular interactions of naringenin in aqueous ethanol/1-propanol solutions, the values of apparent molar volumes (Vϕ) were calculated. The apparent molar volume (Vϕ) of naringenin in the (ethanol/1-propanol + water) solutions at T = (293.15 to 323.15) K and alcohols molality = (24.00, 28.00, 32.00, 36.00 and 40.00) mol·kg−1 was computed from the experimental density data using the following equation: Vφ = M /ρ − 1000(ρ − ρ0 )/(mρρ0 )

(2)

where M and m are the molar mass and molality of naringenin, ρ0 and ρ are the densities of solvent (ethanol/1-propanol + water) and the solution (naringenin + ethanol/1-propanol + water), respectively. The data of density for naringenin in aqueous solutions of ethanol/1-propanol are reported in Table 3 and were plotted in Figures S2 and S3 (Supporting Information). The (Vϕ) values of the investigated systems at T = (293.15 to 323.15) K are presented in Table 3 and depicted graphically in Figures S4 and S5 (Supporting Information). According to Table 3, the Vϕ values are positive and decrease with a rise in temperature and increase with increasing the concentration of naringenin in the aqueous solutions at fixed temperature. The standard partial molar volume (V0ϕ) can be described by the linearly analysis of Vϕ versus the molality of naringenin according to the following equation: Vφ = V φ0 + SV m

mnaringenin and Wnaringenin are the molality and the mass percent of naringenin in aqueous ethanol or 1-propanol solutions. methanol and m1‑propanol are the molality of ethanol or 1-propanol in aqueous solutions, respectively. Wethanol and W1‑propanol are the mass fraction of ethanol or 1-propanol in aqueous solutions. Standard uncertainties u for the molality of solute and solvents are u(mnaringenin) = 0.0001 mol·kg−1; u(methanol) = u(m1‑propanol) = 0.01 mol·kg−1, u(T) = 0.01 K.

volume and SV is the experimental slope which indicates the solute−solute interactions. At infinite dilution, each solute is surrounded only by the solvent molecules and is infinitely distant from other solutes. It follows that V0ϕ is unaffected by solute− solute interaction, and it is a measure only of the solute−solvent interaction.7 Values of V0ϕand SV are given in Table 4. From Table 4, it is also observed that the SV values for the studied systems are positive which indicate the presence of solute−solute interactions. The smaller values of SV compared to V0ϕ emphasize

that solute−solvent interactions dominate over solute−solute interactions. The variation tendency of the standard partial molar volume (V0ϕ) of naringenin with the molality of ethanol and 1-propanol were plotted in Figure 1a,b. It also can be seen from Figure 1 that at low concentrations of alcohols the V0ϕ values of naringenin increased at first then by rising the ethanol/ 1-propanol concentration decreased. The maximum value of corresponding molality of ethanol and 1-propanol was 28.00 and 32.00 mol·kg−1, respectively. The large amount of (V0ϕ) in 3235

msolvent and Wsolvent are the molality and the mass fraction of ethanol and 1-propanol in aqueous solutions, respectively. u(methanol) = u(m1‑propanol) = 0.01 mol·kg−1, u(T) = 0.01 K, and the combined expanded uncertainties uc(B (×103)) = 0.02 m3·mol−1

The partial molar volume of the solute (V̅ ) in the studied system could be calculated by apparent molar volume (Vϕ) according to eq 4:

1-propanol solutions can be explained by the longer alkyl chains in the 1-propanol molecule. The 1-propanol’s longer alkyl chains reinforce the cooperativity of hydrogen bonds between 1-propanol and water molecules in the hydration shell. This phenomenon weakens the hydrophobic interactions more than it does in ethanol, so the values of (V0ϕ) are larger in the 1-propanol solution. The variation tendency of the standard partial molar volume (V0ϕ) may be explained that at the water-rich region, the nonpolar group of naringenin makes a hydrophobic hydration layer. By increasing the alcohols concentration, the hydrophobic hydration layer of naringenin was disrupted and resulted in the increase values of V0ϕ due to the strong hydrogen bonding between alcohols and water molecules. This effect is highest at maximum value of V0ϕ. A greater increase of alcohols concentration in the alcohol-rich region causes an increase in the hydrophobic−hydrophobic and hydrophilic−hydrophobic interactions between naringenin and alcohols. These interactions have a negative contribution on volume and would lead to a reduction in the standard partial molar volume (V0ϕ). It can be seen from Figure 1 that the V0ϕ values of naringenin decrease with the increase in temperature. This can be interpreted in terms of releasing some water molecules from the hydrophobic hydration layer,13 which leads to a negative contribution to V0ϕ. Similar results have been obtained for (7-hydroxy-4-methylcoumarin + ethanol/1-propanol + water) systems.6

ms represents the molality of the solute in the studied system. The calculated V̅ of naringenin in the aqueous alcohol solution were shown in Table 5. These values increase with the increasing concentration of naringenin and decrease with rising temperature in the aqueous solutions. In fact, the variation tendency of V̅ is the same as the apparent molar volume (Vϕ). Viscometric Properties. The measured viscosities of ternary system containing different molalities of (naringenin + ethanol/ 1-propanol + water) at different temperatures were presented in Table 6. These measured data were plotted in Figures S6 and S7. The result showed that the viscosity of the studied solutions increases with a rise in naringenin molality at different concentrations of alcohols. The measured viscosity was analyzed with the Jones−Dole equation,5 The Jones−Dole equation introduce the relative viscosities of solutions as functions of its concentration: ηr = 3237

where ηr is the relative viscosity. η and η0 represent the viscosity of the solution (naringenin + ethanol/1-propanol + water) and solvent (ethanol/1-propanol + water), respectively, c is the molarity of the solution in (mol·dm−3), calculated from molality and density data. The A-coefficient (called Falkenhagen coefficient, representing the solute−solute interactions) can be calculated theoretically but is usually very small for nonelectrolytes and is neglected in eq 5.14 The viscosity B-coefficients were obtained from the slope of linear plot (η/η0 − 1) versus c. The viscosity B-coefficient is a tool to provide valuable information concerning the solute−solvent interactions and their effects on the structure of the solvent in the near environment of the solute molecules.7 Obtained viscosity B-coefficients for ternary solutions (naringenin + ethanol/ 1-propanol + water) are shown in Table 7. The obtained viscosity B-coefficients for the studied system are positive and decrease with increasing temperature. This means that the interactions between solute−solvent are strong and these interactions are further weakened with the increase in temperature. According to Table 7, the higher positive values of the viscosity B-coefficients in the case of 1-propanol as compared to ethanol solutions is due to the hydrophobic side chain in 1-propanol being longer than that of ethanol. The dB/dT values, which give important information regarding the structure-making and structure-breaking role of the solute in solvent media, are a better criterion15 than the B-coefficient. According to the presented values in Table 7, the negative dB/dT values of naringenin in aqueous alcohols solutions show that naringenin acts as a structure maker in aqueous alcohol solutions. The variation of B-coefficients versus the molality of ethanol/ 1-propanol is plotted in Figure 2. As can be from Figure 2, the

mnaringenin and Wnaringenin are the molality and the mass fractions of naringenin in aqueous ethanol/1-propanol solutions. methanol and m1‑propanol are the molality of ethanol/1-propanol in aqueous solutions. Wethanol and W1‑propanol are the mass fraction of ethanol or 1-propanol in aqueous solutions. Standard uncertainties u for the molality of solute and solvents are u(mnaringenin) = 0.0001 mol·kg−1; u(methanol) = u(m1‑propanol) = 0.01 mol·kg−1, u(T) = 0.01 K, u(P) = 5 KPa. The standard uncertainty of refractive indices is u(nD) = 0.0005 and the combined expanded uncertainties of molar refraction is uc(Rm(×106)) = 0.005 m3·mol−1.

tendency of B-coefficients versus the molality of ethanol/ 1-propanol is consistent with the result obtained of the (V0ϕ) values. Refractometric Results. Experimental refractive indices data nD for the ternary solutions (naringenin + ethanol/ 1-propanol + water) were measured at T = 298.15 K, and their values were reported in Table 8. There is not much change in Rm within the temperature range, so in this work the refractive indices were measured at 298.25 K. The molar refraction Rm was calculated using Lorentz−Lorenz equation:5 3

R m = [(nD2 − 1)/(nD2 + 2)](∑ xiMi /ρ) i=1

(6)

where xi and Mi are the mole fraction and molecular mass of the components of the ternary solutions. In this work, eq 6 can be described as Rm =

M1 (nD2 − 1) ρ (nD2 + 2)

[1 + m2M 2 + m3M3(1 + m2M 2)] [1 + m2M1 + m3M1(1 + m2M 2)] (7)

M1, M2, and M3 represent the molar mass of water, ethanol/ propanol, and naringenin. m2 represents the molality of ethanol or propanol in water, m3 represents the molality of naringenin in the alcohol aqueous solution. The calculated molar refractions of the investigated solutions are also shown in Table 8. The variation of Rm at 298.15 K against different molalities of naringenin in ethanol/propanol is plotted in Figure 3. The value of Rm is a measure of molecular polarizability. As can be seen from Figure 3, the Rm values increase linearly with rising concentration of alcohols which indicates high polarizability of naringenin in aqueous ethanol/propanol solutions.7

CONCLUSIONS In this work, various thermophysical parameters were calculated for the alcohol aqueous solutions of (naringenin + ethanol/ 1-propanol + water) at different temperatures and alcohol concentrations from the experimental density, viscosity, and refractive index data. The calculated parameters, such as standard partial molar volume and viscosity B-coefficients, decrease with an increase in temperature and reach a maximum with increasing solvent concentration, suggesting that with an increase in alcohols concentration the hydrophobic hydration layer of naringenin was disrupted, providing an enhancement in hydrophobic−hydrophobic and hydrophilic−hydrophobic interactions between solute and solvent in the alcohol-rich region.

The viscosity B-coefficient values of naringenin in the ternary aqueous solutions of ethanol/1-propanol show that naringenin acts as a structure-making agent because of the negative dB/dT values. The high polarizability of naringenin in aqueous ethanol/ 1-propanol solutions causes the Rm values to increase linearly with an increase in the concentration of alcohols.
