Effects of Chrysanthemum Extract Drinks on Sociopsychological Stress

The effects of anti-stress chrysanthemum flower (ASCF) extract drink (ASCF-0.1% and ASCF-0.5% concentrations) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets and given free access to water containing these ingredients for 18 days. Psychological stress/sociopsychologcal stress exposed by foot-shock for 1 hour for 3 days. Both ASCF-0.1 and ASCF-0.5 groups in the sociopsychological stress resulted in a significant decrease of 28.1% and 27.3% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretions in the brain were significantly increased 49.7% and 53.9%, respectively, in ASCF-0.1 and ASCF-0.5 groups compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxyphenylethy-leneglycol sulfate) levels in the brain resulted in a marked decreases of 12.9% and 16.6%, respectively in ASCF-0.1 and ASCF-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASCF-0.1 and ASCF-0.5 groups resulted in a significantly increase of 71.3% and 81.0%, respectively, compared with control group. These results suggest that anti-stress chrysanthemum flower (ASCF) drink can effectively ridded the sociopsychological stress.
