Sarcandra glabra (Thunb.) Nakai is a traditional Chinese herbal medicine and dietary supplement used for treating several diseases. The anti-diabetic activity of S. glabra polysaccharides is reported for the first time. The in vitro α-glucosidase inhibition assay indicated that the acidic S. glabra
Multiple techniques including high performance size-exclusion chromatography (HPSEC), Fourier-transform infrared spectroscopy (FT-IR) and pre-column derivatization high-performance liquid chromatography (PCD-HPLC) were applied to the fingerprint analysis of the polysaccharides from Sarcandra glabra
A carboxymethylated polysaccharide (CMSERP) was prepared from the residue of Sarcandra glabra (Thunb.) Nakai. CMSERP was mainly composed of galacturonic acid (GalA), glucose (Glc), galactose (Gal), glucuronic acid (GlcA), arabinose (Ara), rhamnose (Rha), xylose (Xyl), ribose (Rib), and fucose (Fuc)
An acidic polysaccharide (SERP1) was isolated from the residue of Sarcandra glabra (Thunb.) Nakai by water extraction and purified by decoloration and ion exchange chromatography. The structure of SERP1 was determined by HPLC, HPSEC-MALLS, FT-IR, and NMR. The results indicated that SERP1 was a
Response surface methodology (RSM) was employed to optimize the parameters for polysaccharide extracted from the aerial parts of Sarcandra glabra (SGP). The optimum conditions were predicted as follows, ratio of water to raw material at 30, extracting temperature at 85 °C, extracting duration at 3
An acidic polysaccharide (SGP-2), with a molecular weight of 1880 kDa, was purified from the defatted whole-plant of Sarcandra glabra (Thunb.) Nakai. SGP-2 is mainly composed of glucose, galactose, mannose, arabinose and galacturonic acid in a molar ratio of 12.19 : 8.68 : 6.03 : 1.00 : 15.24. The
Two proteoglycans (HPP and LPP) with different ratios of protein/polysaccharide were extracted from S. glabra. The chemical compositions, relative average molecular weights, monosaccharide compositions, FT-IR spectra, and rheological properties of the two proteoglycans were determined. The results
