“…It has been reported that polysaccharides from jujube were pectin-like glycan mainly composed of galacturonic acid, and different neutral sugar of arabinose, galactose, glucose, mannose, and rhamnose, etc. [ 6 ]. Ji, et al [ 27 ] isolated a galacturonic acid-rich polysaccharide from Muzao which was identified to be composed of rhamnose, arabinose, galactose, and galacturonic acid at a molar ratio of 1.74: 2.00: 1.00: 18.69.…”

“…It was described to possess the capacity to nourish Qi and blood, and improve the digestive system and sleep quality [ 2 , 3 ]. Pharmacological studies have found that jujube could exhibit protection effects on liver, immunomodulatory, sedation, anti-cancer, antioxidant, and anti-inflammatory activities due to its various chemical ingredients [ 4 , 5 , 6 ].…”

“…Most of these polysaccharides were extracted by hot water and further isolated by ionic exchange chromatograph (such as DEAE resin). Structural analysis indicated that polysaccharides from jujubes were mostly acidic pectin-like heteroglycan, including homogalacturonan (HG), rhamnogalacturonan-I (RG-I), and substituted galacturonans (RG-II), with molecular weight ranging from 10 4 to 10 6 Da [ 1 , 6 ]. These polysaccharide fractions always mix together to form the cell wall structure of jujubes.…”

A homogalacturonan pectin (HG, designated as WJP-F80) was extracted from the peel of winter jujube (Zizyphus jujuba Mill. Cv. Dongzao) and separated via ethanol-graded precipitation. The structural and conformational features were elucidated through HPAEC-PAD, GC-MS, 2D NMR, and HPSEC-MALLS studies. In vivo assessments were carried out to evaluate the hepatoprotective effects of WJP-F80 against CCl4-induced injury of mice. Results showed that WJP-F80 was a linear 1,4-α-galacturonan with partially methyl-esterified at O-6 of GalpA and occasionally acetylation. The Mw of WJP-F80 was determined as 45.3 kDa, the polydispersity was calculated as 1.56, and the Rg was measured as 22.7 nm in 0.1 M NaNO3. The conformational analysis revealed that WJP-F80 exhibited as rigid stiff chain in low Mw range, while aggregation by self-assembly of HG chains lead to high Mw and random coil conformation. In vivo studies indicated that WJP-F80 can protect the livers of mice from acute injury induced via CCl4 by decreasing the serum biochemical markers of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) to normal levels. This work provides a theoretical basis for the value-added deep processing of winter jujube.

“…Os polissacarídeos são polímeros de alto peso molecular, os quais podem ser constituídos de um único ou de diferentes tipos de carboidratos. Estes polímeros são formados pela desidratação e condensação de múltiplas moléculas de monossacarídeos, por meio de ligações glicosídicas (RUAN et al, 2022). A ligação glicosídica ocorre via ligação da hidroxila hemiacetálica do carbono 1( C 1 ) de uma unidade de monossacarídeo com uma das hidroxilas do carboidrato vizinho, ocorrendo consequentemente a eliminação de uma molécula de água (Figura1) .…”

“…Nos polissacarídeos, as diferentes composições de carboidratos, assim como das suas proporções, dos sítios de ligações glicosídicas e arranjos espaciais, resultam numa extensa diversidade estrutural, que conferem atividades biológicas distintas para esses polímeros. Devido às atividades biológicas e baixa toxicidade de polissacarídeos, essas substâncias despertam o interesse de pesquisadores, como na área da química de produtos naturais que utilizam ferramentas analíticas para a sua determinação (RUAN et al, 2022;SONG et al, 2021).…”

This research explores the potential for generating biogas and clean energy by processing organic waste, a process that can become a sustainable solution to Syria's energy needs. Focusing on agricultural residues generated from citrus fruit orange, date, and jujube cultivation in Syria, this study evaluates the potential for anaerobic digestion of these residues for biogas production. It highlights the influence of substrate composition and the optimization of fermentation processes on biogas and methane production. The study focuses on evaluating the anaerobic digestion process by examining various dosages ranging from 20% to 50% dry matter for citrus orange waste, and different types of substrate with a fixed ratio of 20% substrate dry matter. It specifically discusses the factors influencing the inhibitory effect of anaerobic digestion, giving particular consideration to orange waste, a significant byproduct of the citrus industry. The biogas produced maintained a stable methane content when a citrus‐to‐inoculum ratio of 30:70 was used. Jujube waste, characterized by a composition rich in cellulose and hemicellulose, exhibited a higher potential for biogas and methane generation among the fruit waste investigated, particularly when combined with the inoculum in a 20:80 ratio. The research findings underscore the potential of using Syrian agricultural residues, including orange citrus peel, date, and jujube fruit, for the production of biogas through anaerobic digestion.
