Action of (2-->1)Fructo-oligopolysaccharide fraction of Chlorophytum borivilianum against Streptozotocin-Induced oxidative stress.

A fructo-oligosaccharide was isolated from Chlorophytum borivilianum and identified as O-beta-D-fructofuranosyl-(2-->1)-(beta-D-fructofuranosyl) (n)-(2-->1)-alpha-D-glucopyranoside (n = 5 - 30) using high-pressure anion exchange chromatography, MALDI-MS, NMR, GC, HPTLC and chemical analysis. The extract and the fructo-oligosaccharide were found to have significant antidiabetic activity with the blood sugar levels being 118.32 +/- 3.56 and 110.21 +/- 4.22, respectively, as compared to the control value of 231.25 +/- 3.03 along with moderate antioxidant activity in streptozotocin-induced diabetic animals.
