초록

The research was conducted to provide basicinformation for store temperature which were low and roomtemperature and packing methods which were vacuum, packingand nitrogen of 3 year-old Platycodon grandiflorum. Weinvestigated hardness and content of saponins, 1) platycodinD3, 2) polygalacin D and 3) deapioplatycodin D, in Platycodongrandiflorum and hardness of Platycodon grandiflorum, whichwere reduced by increasing storage period and decreasedwith increasing storing temperature, respectively. The packedstoring method was better than others storing methods inlow temperature. The high root hardness was significantlyrelated with storing temperature and methods. The contentof saponins in Platycodon grandiflorum, i.e., platycodin D3and polygalacin D were reduced during storing period,however, the content of deapioplatycodin D was increasedduring storing period.
