“…Pressurized liquid extraction (PLE), also known as accelerated solvent extraction (ASE), is a method of isolation wherein it uses organic solvents as an extractant at elevated pressure at a conventional temperature. This method helps to increase the solubility of the analytes and improve the desorption from the matrix as it maintains the solvent in a liquid state [43] . The sample is put in an extraction cell with an organic solvent at an elevated temperature and pressure.…”

“…Moreover, it can also dissolve a wide range of biomass matrices resulting in easier access to the compounds being studied. IL's aqueous solution also improves solvation performance due to its hydrotropic nature allowing an advanced extraction [43] . The solubility data of compounds is one of the most essential factors needed to be considered to be able to perform a successful extraction and separation process.…”

Analytical chemistry is a branch of science that deals with chemical analysis responding to changing conditions. It is related to phytochemistry that deals with plant phytochemicals which are beneficial for preventing illnesses and maintaining long-term health. This review comprehensively studied the plant Vitex negundo Linn (Lagundi) by exploring different analytical methods utilized in extracting its common active secondary metabolites depending on its efficiency, selectivity and convenience. In this paper, most studies that had been gathered employed high yield, efficiency, and selectivity, making it difficult to determine a standardized method for V. negundo Linn due to the optimal environmental conditions and solvents that are being utilized. Hence, optimization remains vital for the variety of applications in extracting bioactive compounds from V. negundo Linn to achieve a minimum level of impurities and an acceptable degree of reproducibility and repeatability of bioactive compounds of interest.

“…Carbon dioxide (probably the most used supercritical fluid) is nontoxic, nonflammable, can act at low temperatures, and is relatively cheap; unfortunately, the solubility of carbohydrates in the supercritical phase of this fluid is low [12]. Some of the advantages of supercritical fluid extraction are solvating powers similar to liquid organic solvents, high solute diffusivities, lower viscosity, lower surface tension, and the possibility of adjusting the solvating power by changing pressure or temperature [9].…”

“…Moreover, C 18 cartridges are useful for the fractionation of (1-4)-α-glucans depending on their degree of polymerization. Ion-exchange SPEs are used for desalting oligosaccharides mixtures, but care should be taken to avoid the loss of charged sugars during their purification [12]. Solid-phase extraction on graphitized carbon material upon enzymatic amyloglucosidase pre-treatment enabled a good recovery and a selective purification of the different GOS structures from the exceeding amounts of particularly lactose-and maltodextrin-rich preparations [17].…”

“…The choice for selecting the UF and NF membrane is mainly based on the value of the molecular weight cutoff (MWCO), which is the molecular mass of the smallest compound retained to an extent larger than 90% [12]. Mehra et al [28] employed the membrane filtration technology to produce powders enriched in bovine milk oligosaccharides (BMOs) using mother liquor (the liquid remaining after the separation of lactose crystals from whey UF permeate) as a starting raw material.…”

Lactose is a principal component of the milk obtained from the mammals. Milk also contains several other sugars such as monosaccharides and oligosaccharides in low concentrations. Lactose has reactive functional groups and can be converted to valuable food-grade derivatives for commercial applications through chemical and/or enzymatic reactions. Physical and chemical properties of carbohydrates determine the methods that can be used for their fractionation and purification. In this chapter, the advanced extraction techniques for fractionation and analytical methodologies applied for the determination of different carbohydrates of milk (lactose, lactulose, and oligosaccharides) are summarized.The main aim of this contribution is to provide the reader with a broad view on the recent fractionation and analytical techniques employed for the analysis of carbohydrates in dairy foods and their applications in food and pharmaceutical industry.
