Abstract:
Objective To investigate the effects of red ginseng saponin components A and B on 15 neurochemicals in rat plasma. Methods Saponin components A and B were prepared from red ginseng total saponin by macroporous adsorption resin. The composition and contents of saponin components A and B were detected using UPLC-Q-TOF-MS/MS method. A total of 15 kinds of neurochemical substances such as dopamine (DA), adrenaline (E), norepinephrine (NE), serotonin (5-HT), 5-hydroxytryptamine (5-hydroxytryptamine), tyrosine (Tyr), glycine (Gly), glutamic acid (Glu), glutamine (Gln), aspartic acid (Asp), taurine (Tau), serine (Ser), tryptophan (Try), acetylcholine (Ach), and histamine (His) were measured by high performance liquid chromatography- mass spectrometry (UPLC-QQQ-MS/MS). Results By analyzing the intrinsic relationship between saponin composition and amount of neurochemicals, it was found that components A and B had significant differences in saponin composition, and the larger polar saponins were mainly concentrated in component A. The polar of saponin contained in B is relatively small. The levels of Ach, Tau, Glu, Gln, Asp, Tyr, E, NE, and DA in rat plasma of each dose group were increased, and the plasma levels of Gly, His, 5-HT, Ser, HIAA, and Try were significantly increased and positively correlated with the dose, suggesting that the larger polar saponins could increase the excitatory neurochemical content and the smaller saponin fraction inhibitory neurochemicals. Conclusion Red ginseng has a moderating effect on the content of central nervous system. The content of smaller polar saponins is related to the maintenance of brain activity, improvement of memory function, prevention of brain fatigue, maintenance of awakening and nervous system of anti-aging, while the larger polar saponin fraction is associated with the regulation of psychiatric rhythm, reduction of stress response and improvement of sleeping.
