“…2 As previously reported, the absorbances at 1030 cm −1 and 895 cm −1 can be referred to as the characteristic peaks of C-O stretching and C-O-C (⊎-glycosidic linkage) of cellulose, respectively. 38 Lignin peaks were observed at around 1200-1300 cm −1 in the spectrum. This is referred to as aromatic skeletal vibration.…”

“…Lignin is a strongly crosslinked phenolic polymer, whereas hemicellulose is a branching multiple polysaccharide polymer made up of several kinds of sugars. 10 Hydrolysis with a strong acid such as sulfuric or hydrochloric acid is a well-known method for removing the amorphous material and isolating CNCs from natural fibers. However, the most practised method includes several chemical treatment steps, i.e.…”

The utilization of cellulose nanocrystals (CNCs) extracted from natural fibers is one way to make the most use of renewable resources. Isolation of CNCs normally requires a multi‐step process that includes an alkali treatment, bleaching (using sodium chlorite) and acid hydrolysis (sulfuric or hydrochloric acid). Here, a new approach for extracting CNCs from green Luffa cylindrica biomaterial, one type of natural fiber found in tropical countries, was developed via an alkali treatment and oxidative degradation using sodium hypochlorite, without an acid hydrolysis step. The diameter and length of the obtained CNCs were about 7.5 ± 2.2 nm and 266.9 ± 25.2 nm, respectively, with a considerably higher percentage yield (40%) compared to the traditional hydrolyzed‐cellulose nanocrystals (H‐CNCs) (28%). The zeta potential of CNCs and H‐CNCs in neutral water was −29.2 ± 0.5 mV and −13.1 ± 0.5 mV, respectively. Negative charges on CNC surfaces play an important role in the reduced aggregation of CNC suspensions. The degrees of crystallinity of CNCs (78.5%) and H‐CNCs (79.2%) are comparable. Moreover, the degrees of polymerization of CNCs and H‐CNCs were 297.21 and 226.64, respectively. The method developed is considered an easy operation with low pollution, low‐cost chemicals and a time‐ and energy‐saving process. © 2022 Society of Industrial Chemistry.

“…First of all, it was worth noting that the presence of sucrose might contribute itself to the viscosity of the solution. Also was the fact that the hydration of its molecule in the solution will reduce the amount of free water, strengthening the interaction of the CCPP molecular chain and enhancing polymerization of hydrogen bonds between the polysaccharides, thus leading to the increased viscosity of the polysaccharide solution [26][27][28][29][30][31][32][33][34][35].…”

The extraction condition of crude polysaccharides from Codonopsis pilosula by hot water reflux method was studied and the results analyzed by kinetic model. Then, the extraction rate and maximum extraction temperature were determined. furthermore, the thermal and pH stability and the rheological properties of the crude polysaccharide were also studied. crude Codonopsis pilosula polysaccharide (CCPP) under different conditions was extracted by hot water reflux method, the content was determined by phenol-sulfuric acid and DNS method, and the kinetic model of the extraction process was established. The viscosity was determined under different solute concentration, salt concentration, rotation speed, pH, and temperature. The thermal stability and pH stability were determined; the protein content and sulfate ion content were determined by the coomassie brilliant blue method and barium sulfate turbidimetry method, respectively. The yield of CCPP by the hot water reflux method was 25.72%. At 50 oC, the maximum extraction concentration, the rate constant and the linear relationship between the rate constant and the time were obtained at different ratios of material to liquid. The extraction process of this experiment coincided with Fick`s second law, R2 was greater than 0.88 and with the increase of extraction time, the dissolution rate increased, but with the increase of the ratio of material to liquid, the dissolution rate was decreased. CCPP showed a loss of polysaccharide fluidity as temperature increased and was affected by pH change. The apparent viscosity was affected by a change in solute concentration, temperature, pH, rotation speed and salt and sucrose concentrations.

“…14 According to the excellent characteristics of DES, a large number of complex natural products are fully extracted, including avonoids, polyphenols and polysaccharides. [15][16][17] Moreover, ultrasound-assisted DES extraction (UAE) possesses the advantages of both ultrasound extraction and DES extraction, which is able to maximize the yield of natural active ingredients as well as saving time and energy. 18 All of the above points suggest that DES expands the approach to natural active substance extraction.…”
