Abstract

Terpenoids such as ginsenosides are the most important phytochemicals and functional components in ginseng. Commercial sterilizing with high temperature and high pressure is also one of the common methods of ginseng food processing. However, the changes of terpenoids in fresh ginsengs commercially sterilized are unclear. In this study, fresh ginseng pulp (FGP) was commercially sterilized at 121℃ for 30 min, and terpenoid compounds were analyzed by widely targeted metabolomics based on UPLC-ESI-MS/MS system. The commercial sterilization induced the changes of 88 terpenoid compounds including 30 types of ginsenosides, and many minor ginsenoside Rh4, Rg6, Rk2, F4, Rs3, Rk3, Rk1, Rg5, Rg3, Rg4 were remarkably increased in fresh ginseng pulp. Importantly, the ginsenoside ST3 was detected and F4, Rg3, and Rg5 were also found in fresh ginseng pulp. Commercial sterilizing at 121℃ for 30 min will remarkably affect the species and number of ginsenosides in ginseng food.
