초록

This study was carried out to investigate the antioxidant activities and the contents of antioxidant compounds in extracts derived from 23 medicinal crops. Dried plant materials were extracted by 80% methanol and the extracts were used to experiment. The levels of total phenolic compounds were much higher in Oenothera biennis, Houttuynia cordata, Cedrela sinensis, Rhus javanica, Artemisia annua, Reynoutria sachalinensis, and Dendropanax morbifera compared with other crops. On the other hand, the total phenolic compound levels in Carthamus tinctorius, Polygonum multiflorus, Ginko biloba, Solanum nigrum, and Saposhnikovia divaricata were relatively low. The total flavonoid contents were highest in H. cordata, followed by D. morbifera, A. annua, A. continentalis and O. biennis. DPPH activity was significantly higher in A. annua, R. javanica, C. sinensis, D. morbifera and O. biennis, and ABTS activity was significantly higher in R. javanica, C. sinensis, O. biennis, R. sachalinensis, A. annua, and D. morbifera than other plants. These results suggest that O. biennis, A. annua, R. javanica, D. morbifera, and R. sachalinensis can be utilized as food additives and natural antioxidants due to their strong antioxidant activity.
