Abstract

|
Korean ginseng (Panax ginseng) generally has a good safety profile and contains many bioactive substances, such as ginsenosides or panaxosides. Korean red ginseng might help to stabilize the sympathetic nervous system and improve cognition in individuals. Soft red ginseng is produced by new processing technology. This study focused on investigating whether soft red ginseng produced under the new processing technology reduces or improves the existing antioxidant effects. No significant difference in 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) scavenging activity was found between soft red ginseng and ready-made red ginseng (p<0.05). Soft red ginseng extract showed higher 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and hydroxyl radical (OH) scavenging activity than other ginseng extracts. OH scavenging activity was significantly different across three groups (raw ginseng, soft red ginseng, and red ginseng sap) (p<0.05). Nitric oxide (NO) scavenging activity was also significantly different among raw ginseng, soft red ginseng, and purchased red ginseng liquid products (p<0.05). Many calcium crystals appeared on the electron microscope in soft red ginseng. Magnesium and potassium showed no significant difference between soft red ginseng and hard red ginseng. The extract of soft red ginseng scavenged different free radicals efficiently due to the presence of DPPH and OH and may help treat free radical-induced diseases.
