Abstract
The research was conducted to provide basic information for store temperature which were low and room temperature and packing methods which were vacuum, packing and nitrogen of 3 year-old Platycodon grandiflorum. We investigated hardness and content of saponins, 1) platycodin D3, 2) polygalacin D and 3) deapioplatycodin D, in Platycodon grandiflorum and hardness of Platycodon grandiflorum, which were reduced by increasing storage period and decreased with increasing storing temperature, respectively. The packed storing method was better than others storing methods in low temperature. The high root hardness was significantly related with storing temperature and methods. The content of saponins in Platycodon grandiflorum, i.e., platycodin D3 and polygalacin D were reduced during storing period, however, the content of deapioplatycodin D was increased during storing period.
