Abstract:
The liquid-chromatography-mass technology was used in the metabolomic analysis of mouse's blood 1 hour after exhaustive exercise,in order to explore the potential mechanism of Rhodiola in fatigue elimination of exhaustive exercise mouse.The exhaustive mouse model was made by loaded-swimming.A total of 24 mice were randomly divided into theRhodiola + exercise group,exercise group andno-exercise group.The dose of Rhodiola was 0.4375 g·kg-1·d-1.The loaded-swimming was conducted after two successive weeks of medication.Blood was collected 1 h after swimming for the sample preparation.The enzyme assay and anthrone colorimetry were used to test blood lactate acid and glucose,respectively.UFLC-Q-TOF was used to detect metabolic profiles of each group.The principal component analysis (PCA),orthogonal partial least squares discriminant analysis (OPLS-DA) and heat map analysis were used to compare differences among groups with score chart and to obtain the characteristics biomarkers by load chart.The results showed that the blood lactate acid level of theRhodiola+ exercise group was significantly lower than that of theexercise group.And the glucose level of theRhodiola+ exercise group was significantly higher than that of theexercise group.The metabolomic analysis showed that there were no obvious changes on 1,25-(OH)2D3,diacylglycerol (DG) and inositol triphosphate (IP3).All three materials in theRhodiola + exercise group were significantly lower than those of theexercise group.They were much closer to theno-exercise group.And all three materials were related to the increasing of muscle tension.It was concluded that Rhodiola had the function of promoting fatigue eliminating.This effect may be related to cell membrane protection,regulation of 1,25-(OH)2-D3→IP3,DG pathway,and relieving of muscle tension after exercises.
