“…There is a growing need to develop efficient and selective separation processes. Several separation approaches, such as liquid-liquid extraction, membrane filtration, ion exchange, and adsorption, have become mainstream methods for herbal medicine separation, and macroporous resin (MR) adsorption is one of the most commonly used methods due to its low-cost, high-efficiency, easy-recycling, and simple scaling-up performance [10]. The principle of separation by MRs is based on molecule adsorption in differences of molecule polarity, weight, and size.…”

A separation method was developed for the preparative separation and enrichment of the non-caloric sweetener mogroside V from Siraitia grosvenorii. The adsorption properties of six macroporous resins were evaluated. Results showed that HZ 806 resin offered the best adsorption and desorption capacities. Based on the adsorption experiments on HZ 806, the adsorption data were found to fit the Freundlich model well. The pseudo-second-order kinetic model showed the highest correlation with the experimental results. Separation was performed with deionized water and 40% aqueous ethanol solution as mobile phases. In a typical run, 100 g of herb was processed and 3.38 g of mogroside V with a purity of 10.7% was harvested. This separation method provided a 15.1-fold increase in the purification factor from 0.5% to 10.7%. The present study showed that HZ 806 resins were effective for the separation and enrichment of mogroside V from S. grosvenorii.

“…The affinity is mainly chemically based. Various researchers studied the impact of different solvents on sesame oil extraction, [9] used n-hexane, cyclohexane, benzene, mixture of n-hexane/chloroform (2:1, v/v), chloroform, acetic ether, butanol and acetone, on the other hand [1] used hexane and [10] used compressed popane and supercritical carbon dioxide. Majority of researchers found that n-hexane yields higher extraction percentages making it the optimum solvent.…”

In this study, the optimum operating conditions for sesame oil extraction were studied. N-hexane was used as a solvent. Different variables were investigated; sesame seeds particle sizes, ratio of solvent to seeds mass, contact time, stirring effect, roasting impact and extraction temperatures. Results obtained showed that higher rates of extraction were obtained when roasting sesame seed to 150˚C. The ratio of solvent to seeds found to be 6:1 gave higher extraction. Moreover, stirring speed was tested and had been optimized to 600 rpm. Finally, the extraction under heating was studied and results showed that increasing operating temperature to more than 40˚C did not increase extraction efficiency.

“…Recently, macroporous resins have been considered promising adsorption materials because of their large surface area, high stability, low operational cost, reduced solvent consumption and easy regeneration [16,17]. Resins have been widely used to purify many types of secondary metabolites such as flavonoids, glycosides, saponins, alkaloids, and lignans [18][19][20][21][22][23][24]. In our previous study, macroporous resins have been successfully applied in large-scale separation of chlorogenic acid from Helianthus tuberosus leaves [25].…”
