Abstract
- • A homogenous polysaccharide SPS60 was isolated from Sabia parviflora. • The monosaccharide component of SPS60 was glucose. • SPS60 showed significant hepatoprotective activity. • The AFM images showed SPS60 was a massive sphere with a diameter of 21 nm. The extraction, purification, structure and hepatoprotective activity of a homogenous polysaccharide (SPS60) from Sabia parviflora were investigated. SPS60 was screened after purification with Sephadex G-100 and showed the excellent hepatoprotective activity. Its structural characteristics were investigated by Time of flight mass spectrometry (TOF-MS), PMP Pre-column derivatization-HPLC (PMP-HPLC), nuclear magnetic resonance (NMR) spectroscopy and Atomic Force Microscopy (AFM). The results showed that SPS60 possessed the molecular weight of 16900 Da and the monosaccharide component was glucose, as well as a 1 → 6 glycosidic bond. The results of atomic force microscopy (AFM) show that SPS60 is a blocky sphere in solution. Furthermore, the SPS60 could significantly improve the survival rate of LO2 hepatocytes which were damaged by CCl 4. Therefore, SPS60 may be an active substance of S. parviflora as a local functional tea. [ABSTRACT FROM AUTHOR]
