Anti-fatigue activity of polysaccharides extract from Radix Rehmanniae Preparata

International Journal of Biological Macromolecules, 2012
The anti-fatigue effects of the Radix Rehmanniae Preparata polysaccharides (RRPP) were studied in mice. The RRPP were orally administered at doses of 50, 100 and 200 mg/kg for 4 weeks and the anti-fatigue activity was evaluated using a weight-loaded swimming test, along with the determination of serum urea nitrogen (SUN), hepatic glycogen and blood ...

Advances in modern research on pharmacological effects of Radix Rehmanniae

AIP Conference Proceedings, 2020
Radix Rehmanniae Preparata, also known as Rehmannia glutinosa, is sweet in taste and mild in nature. It is produced by processing from the root tubers of Rehmannia in the Scrophulariaceae. Radix Rehmanniae contains catalpol, carbohydrates, digoxigenin, amino acids, digoxigenin (ABD, etc.) and a variety of chemical trace elements. It is commonly used in

Amelioration of Diabetic Nephropathy by Dried Rehmanniae Radix (Di Huang) Extract

The American Journal of Chinese Medicine, 2004
The effects of dried Rehmanniae Radix (Di Huang) extract were investigated using a diabetic nephropathy model: rats given streptozotocin after nephrectomy. The results showed that this crude drug reduced the magnitudes of the increases in glucose, urea nitrogen, 5-hydroxymethylfurfural and thiobarbituric acid (TBA)-reactive substance levels, with the ...

Purification and structural analysis of a novel polysaccharide from Rehmannia Radix Praeparata

Chemical Biology & Drug Design, 2023
AbstractIn this paper, the purification, structure, and antioxidant activity of Rehmannia Radix Praeparata polysaccharide (RRPP) were studied. The RRPP was separated using DEAE‐52 cellulose and Sephadex G‐100. The RRPP consisted of xylose, glucose, rhamnose, galactose, and mannose in ratios of 10.64:5.58:3.52:1.39:1.0.
