Abstract: Two oligosaccharides, a heptasaccharide (HS) and an octasaccharide (OS), isolated from Paris polyphylla var. yunnanensis, stimulated the growth and saponin accumulation of Panax ginseng hairy roots at 5-30 mg l -1. HS and OS at 30 mg l -1, fed separately to hairy root cultures at 10 days post-inoculation, increased the root biomass dry weight by more than 70% to ∼20 g l -1 from 13 g l -1 and the total saponin content of roots by more than 1-fold to ∼3.5% from 1.6% (w/w). The results suggest that the two oligosaccharides may have plant growth-regulatory activity in plant tissue cultures.
