In vitro and in vivo antioxidant activity of a water-soluble polysaccharide from Dendrobium denneanum.
نویسندگان
چکیده
The water-soluble crude polysaccharide (DDP) obtained from the aqueous extracts of the stem of Dendrobium denneanum through hot water extraction followed by ethanol precipitation, was found to have an average molecular weight (Mw) of about 484.7 kDa. Monosaccharide analysis revealed that DDP was composed of arabinose, xylose, mannose, glucose and galactose in a molar ratio of 1.00:2.66:8.92:34.20:10.16. The investigation of antioxidant activity both in vitro and in vivo showed that DDP is a potential antioxidant.

متن کاملPurification, characterization and antioxidant activities in vitro and in vivo of the polysaccharides from Boletus edulis bull.
A water-soluble polysaccharide (BEBP) was extracted from Boletus edulis Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw), IR and monosaccharide composit...

Bio-guided fractionation of the stems of Dendrobium aurantiacum var. denneanum using a 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay, led to the isolation of three 2-glucosyloxycinnamic acid derivates, namely, cis-melilotoside, trans-melilotoside and dihydromelilotoside, respectively. Their structures were elucidated through the analysis of uni- and bi-dimensional NMR, UV, IR a...
