Do my homeworkAt enhanced concentrations of the hydrotrope, a greater osmotic pressure also expands through the cell wall; therefore, at higher concentrations, a hydrotrope solution penetrates into the cell matrix gradually. There is an initial lag time after which hydrotrope monomers diffuse into the cell wall and undermine the liquid crystalline nature of the bilayer; at this time the swelling of the cell wall is lost. The aqueous solution subsequently penetrates into the cellular matrix and piperine is then transported into the external hydrotrope medium; these are considered the fast stages Raman and Gaikar a. Generally, the extraction rate of piperine depends on the concentration of hydrotrope, temperature, and particle size of the pepper matrix. There is also a distinct relationship between the length of the hydrotropic chain and extraction efficiency. They observed that NaNBBS was the most efficient hydrotrope in dissolving piperine; this ability was attributed to its longer chemical chain. Solubilization also enhances with an increase in hydrophobic volume. This demonstrates that hydrophobic areas existing in the hydrotrope aggregates provide a microenvironment which is compatible with the hydrophobic nature of piperine. It is also conceivable that the presence of a highly hydrophobic solute results in the promotion of aggregation behavior of the hydrotrope Balasubramanian and others Increasing the extraction temperature causes more lysis of the cell and, as a result, the cell wall becomes more permeable to the hydrotrope solution Subbarao and others Disruption and solubilization of the cellulose polymer inside the cell wall reduces the contribution of this polymer to the firmness of the cell wall. Purity of the extracted piperine is also found to decrease significantly when the particle size is reduced. With a decrease of particle size, cell breakage increases and the hydrotrope solution penetrates more effectively into the cellular matrix which leads to solubilization of undesirable solutes along with piperine Raman and Gaikar a. Supercritical fluid extraction of piperine Supercritical fluids are widely used for extracting compounds from natural materials. Supercritical fluid extraction SFE , which has recently become very popular in the spice and aromatic crops industries, is a rapid, selective, efficient, and clean method for the extraction of natural products. Supercritical fluids are very capable to conduct an effective mass transfer, permitting better and quicker penetration into sample matrixes and selective extraction of favorable compounds due to their small viscosities and great molecular diffusivities the same as gases as well as their small surface tension. The most serious drawback of SFE, compared to traditional methods, is its higher investment costs Lang and Wai ; Herrero and others , The only disadvantage regarding the use of CO2 as supercritical fluid is that CO2 has low polarity and might be more suitable for the extraction of nonpolar compounds. For successful extraction not only the affinity of the desired and undesired compounds toward extraction should be considered, but also mass transfer resistances along the path to the specific location of the desired compound, which depend on the structure of the raw material and can play an important role Reverchon and De Marco Temperature is another important parameter which affects the SFE yield. When temperature increases, the solvent power decreases due to reduction in the density of supercritical fluid Rostagno and Prado The most important parameter in SFE is pressure. Increasing the extraction pressure enhances the solvent power, but it reduces the extraction selectivity. Some other effective parameters in SFE are the flow rate of fluid, particle size of the sample subjected to extraction, and extraction duration Reverchon and De Marco They obtained a yellowish semisolid mass with a crystalline constituent. In another investigation carried out by Kurzhals and Hubert , piperine was extracted from pepper using a mixture of CO2 and propane with a molar ratio of They also found that the rate of extraction increased with an increase in temperature because of the enhancement of piperine solubility in carbon dioxide. It was inferred that the enzyme needed an incubation time to hydrolyze the starch present in the black pepper matrix. This incubation time was provided for the enzyme in batch operations, which resulted in the increase in the extraction yield of oleoresin from the pepper matrix. UAE of piperine Soxhlet extraction and batch solvent extraction are traditional extraction techniques with disadvantages such as lengthy extraction time, solvent wasting, and labor intensity. Recently, to overcome the disadvantages associated with conventional methods, new extraction techniques have been developed. UAE is one of these techniques. The mechanism of UAE is based on the cavitation phenomenon and thermal effects, which enhance the mass transfer through the cell wall. Moreover, the collapse of cavitation bubbles causes better cell disruption by formation of microjets due to asymmetrical bubble collapse close to the solid surface Mason and others The frequency, acoustic power, gas atmosphere, hydrostatic pressure, nature, and temperature of the solvent, and geometry of the reactor are among the factors which can affect the cavitation Henglein and Gutierrez High pressures up to bar and temperatures up to K are created due to imploding of these bubbles that can generate high energy and also some interesting physical effects Cintas and Luche These physical and thermal effects cause liquid circulation, cell wall breakage, decline in particle size, and increased mass transfer through cell membranes Yang and Zhang Consequently, solvent penetration into the plant body improves and cell breakage occurs Toma and others and, as a result, the extraction yield in UAE will be increased. Thus, UAE has advantages such as better solvent penetration, lower dependence on the applied solvent, extraction at lower temperatures, lower extraction time, and higher product yields Mason ; Vinatoru It could be applied in an extraction unit where the plant material directly contacts the solvent. Selection of the most appropriate solvent for extraction of the target compounds from the sample is a crucial step in any extraction technique, especially UAE. Polarity index, viscosity, surface tension, and vapor pressure of solvent are the factors that must be considered in the selection of a suitable solvent Sun and others Low vapor pressure of solvent causes less bubble formation, but these bubbles implode with higher force; thus, more of the target compound is extracted. Since continuous exposure to the ultrasound may lead to the degradation of the material, it is always recommended not to use the ultrasound in a continuous mode; therefore a duty cycle is determined for the system, based on which the ultrasound apparatus is turned on and off. Large amplitude waves move across the liquid medium and the bubbles collapse more explosively when the ultrasound power is enhanced Yang and others Temperature affects the solubility, rate of transfer of target compound to the solvent, and also cavitation phenomenon; both the cavitation and thermal effects display significant influences on extraction yield. Cavitation is responsible for the implosion of cavitation bubbles, which causes great agitation. The thermal effect is responsible for the greater solubility of solute and improvement in mass transfer due to a decrease of solvent viscosity Entezari and Kruus ; Raso and others In an attempt to use UAE, Rathod and Rathod used 3 different solvents acetone, ethanol, and hexane for extracting piperine from Piper longum, and they observed that acetone gave the maximum yield 4. Although acetone and ethanol approximately have the same polarity index, higher yield was obtained using acetone due to greater diffusion into the solid matrix owing to the lower viscosity of acetone. Since the distinction in extraction yield obtained by acetone and ethanol was not remarkable in their experiment, and considering handling difficulty and the price of acetone, ethanol was selected as the preferred solvent. The authors experimented with They also found out that the piperine extraction yield grew logarithmically up to 18 min, and afterwards a slow increase was observed with extended extraction time. At the optimized condition, maximum extraction yield of 5. ILs have some unique properties over traditional solvents: low vapor pressure, high chemical and electrochemical stability, and high polarity Wasserscheid and Welton ; Aparicio and others The physicochemical properties of ILs, which depend on their structures, have a great effect on the extraction efficiency of the target analyte Cao and others The nature of the ions and their interactions directly affects the physicochemical, thermal, and solvent properties Huddleston and others Zhongguo Yiyuan Zazhi.
