- “A novel polysaccharide (GBP50S2) with antioxidant activity was isolated from Ginkgo biloba.”
Researchers from Department of Natural Products Chemistry, Jinan University, Guangzhou, (Canton), Guangdong, China; have presented an article titled: “Structure characterization and antioxidant activity of a novel polysaccharide isolated from Ginkgo biloba.” 1
The researchers from Jinan University, Guangzhou, have also noted:
- “The structure of GBP50S2 was elucidated on the basis of physico-chemical and instrumental analyses, and its average molecular weight (Mw=2.30×10(5)) was determined by gel permeation chromatography.”
- “The backbone of GBP50S2 was composed of (1–>4)-linked alpha-d-mannopyranosyl residues which branched at O-3.”
- “The three branches consisted of beta-l-rhamnopyranosyl residues, (1–>4)-linked alpha-d-galactopyranosyl terminated with beta-l-rhamnopyranosyl residues, and (1–>3,4)-linked alpha-d-mannopyranosyl terminated with beta-l-rhamnopyranosyl residues, respectively.”
- “In the in vitro antioxidant assay, GBP50S2 was found to possess DPPH radical-scavenging activity and hydroxyl radical-scavenging activity with an IC(50) value of 0.412mg/mL and 0.482mg/mL, respectively.”
