Project description:The study focuses on the purification and structural characterization of Ampelopsis grossedentata polysaccharide (AGPS). The polysaccharide was isolated using DEAE chromatography, and its structure was analyzed through various methods, including NMR and MS. The results identified its chemical composition, confirming its heteropolysaccharide nature. Additionally, the study evaluated its bioactivities, such as anti-inflammatory and immunomodulatory effects, showing its potential as a therapeutic agent for related diseases.
Project description:By characterizing the cell wall proteomes of different sugarcane organs (leaves and stems) at two developmental stages (young vs mature/apical vs basal), it was possible to address unique characteristics in each of them. Four-month-old leaves showed a higher proportion of oxido-reductases and proteins related to lipid metabolism (LM), besides a lower proportion of proteins acting on polysaccharides, in comparison to four-month-old internodes. It was possible to note that sugarcane leaves and young stems have the highest LM rate than all species, which was assumed to be linked to cuticle formation. The data generated enriched the number of cell wall proteins (CWPs) identified in sugarcane, reaching 277. To our knowledge, sugarcane has now the second higher coverage of monocot CWP in plants
