Study on the intestinal metabolism and absorption of polysaccharides from Dendrobium officinale
International Journal of Biological MacromoleculesDendrobium officinale polysaccharide (DOP) is widely recognized for its excellent pharmacological activities, however, the in-depth pharmacokinetic characteristic remains unrevealed, significantly hindering its further development. It was hypothesized that Bacteroides predominantly mediates the in vivo metabolism of DOP via polysaccharide utilization ...

Based on the concept of endophytic fungus, if endophytic fungus can produce the same or similar product as the host plant, which will get rid of the restrictions of farmland, seasonal and pest, the active product could be sustainably obtained. In this study, an endophytic fungus polysaccharide FP showing the similar structure with the host Dendrobium ...

In this report, a water-soluble polysaccharide was obtained from the dried stems of Dendrobium officinale Kimura et Migo by hot-water (70-75°C) extraction and 85% ethanol precipitation, and successively purification by DEAE-cellulose anion-exchange chromatography and gel-permeation chromatography. The D.

In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were

A crude polysaccharide fraction (cDOP) has been determined to be the characteristic marker of Dendrobium officinale, an expensive tea material in Asia, but its chemistry and bioactivity have not been studied. In work reported here, cDOP was destarched (DOP, 90% yield) and separated into two subfraction polysaccharides, DOPa and DOPb, which were ...

[Effects of tree species on polysaccharides content of epiphytic Dendrobium officinale].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2015To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D.

This study compared six extraction techniques, hot water, acid-assised, ultrasound-assisted, microwave-assisted, UV/H₂O₂-assisted, and enzyme-assisted on the structural, antioxidant, and emulsifying properties of Dendrobium officinale polysaccharides (DOPs). Molecular weights ranged from 1155.239 kDa (DOPs-hwe) to 3.139 kDa (DOPs-ee).
