Effect of pulverization on total solid,crude saponin,and acidic polysaccharide contents of dried red ginseng main root were tested.Several particle size samples,including red ginseng main root (non pulverized),10-40 mesh powder,40-100 mesh powder,and >100 mesh powder were used in the extraction.The sequential solvent extraction method (1st:70% EtOH at 70℃ for 12 hr,2nd:70% EtOH at 70℃ for 12 hr,3rd:water at 70℃ for 12 hr) was applied to extract the saponins and acidic polysaccharide.Extraction yield of total solid of pulverized red ginseng (10-40 mesh size) was increased 20% compared to non-pulverized.
