Although immunomodulatory activities of Dendrobium officinale polysaccharide has been investigated for many years, yet the potential contribution of its metabolite derived from intestinal microbes on immunoregulation effect has not been reported. In this study, polysaccharide DOW-5B with average
Dendrobium is a traditional Chinese herb with anti-diabetic effects and has diverse bibenzyls as well as phenanthrenes. Little is known about Dendrobium polyphenols anti-diabetic activities, so, a rich-polyphenols extract of D. loddigesii (DJP) was used for treatment of diabetic

The effect of inorganic phosphate on cell growth, accumulation of polysaccharides together with nutrient utilization was investigated in suspension cultures of protocorm-like bodies of Dendrobium huoshanense. Thirty-day-old cells were transferred into liquid medium with the inoculum density of 100
OBJECTIVE To compare the physicochemical properties and immun activities of polysaccharides extracted from cultures at different development stages of Dendrobium huoshanense. METHODS Polysaccharides were extracted by hot water and alcohol precipitation, and isolated by anion exchange chromatography.
Qualitative and quantitative analysis of specific polysaccharides from ten batches of Dendrobium huoshanense were performed using high performance size exclusion chromatography coupled with multi-angle laser light scattering and refractive index detector (HPSEC-MALLS-RID), gas chromatography-mass
