Abstract:
Background:Fameyes (a mixture of Clematis mandshurica Rupr. extract (CMRE) and Erigeron annuus (L.) Pers. extract (EAPE)) containing scutellarin and chlorogenic acid as major components has been reported to relieve mental stress in human subjects, which is reflected in improved scores in psychometric tests measuring levels of depression, anxi‑ ety, well-being, and mental fitness. The aim of this study was to examine the anti-stress activity of Fameyes and to investigate the mechanisms of the anti-stress activity using in vitro and in vivo models of stresses.
Results:First, we tested the effect of Fameyes on corticosterone-induced cytotoxicity in SH-SY5Y cells (human neurofibroma cell lines). Corticosterone induced apoptosis and decreased cell viability and mitochondrial membrane potential, but treatment with Fameyes inhibited these cytotoxic effects in a dose-dependent manner. However, CMRE and EAPE (components of Fameyes) did not inhibit the cytotoxic effect of corticosterone individually. Next, we tested the effects of Fameyes on rats that were exposed to different kinds of stresses for four weeks. When the stressed rats were treated with Fameyes, their immobility time in forced swim and tail suspension tests decreased. A reduction was also observed in the serum levels of adrenocorticotropic hormone (ACTH) and corticosterone. Furthermore, upon oral administration of Fameyes, serum serotonin levels increased. These in vitro and in vivo results support the anti-stress effects of Fameyes.
Conclusions:In vitro experiments showed anti-stress effects of Fameyes in cell viability, apoptosis, and mitochon‑ drial membrane potential. In addition, in vivo experiments using rats showed anti-stress effects of Fameyes in blood and tissue levels of ACTH, corticosterone, and serotonin, as well as the immobility time in the forced swim and tail sus‑ pension tests. However, we did not specifically investigate which ingredient or ingredients showed anti-stress effects, although we reported that Fameyes contained chlorogenic acid and scutellarin major ingredients.
