    Abstract:
    To evaluate the anti-acute inflammation effects of volatile oils from different processed products of Angelicae Sinensis Radix(AS) in the rat model of acute inflammation established by the metabolomic method. Volatile oil of charred AS (C-VOAS), wine-processed AS (J-VOAS), locally processed AS (T-VOAS) and oil-process AS (Y-VOAS) were applied to intervene the rat acute paw swelling inflammation model induced by Carrageenan. Changes in serum HIS, 5-HT, PGE2 and TNF-α content in rats were detected. Gas chromatography-mass spectrometry was used to detect the metabolites in plasma. Potential biomarkers were investigated according to principal component analysis method and partial least-squares discriminant analysis. According to the results, C-VOAS and J-VOAS could significantly inhibit inflammatory mediators Histamine, 5-hydroxytryptamine, prostaglandin-E2 and cytokine tumor necrosis factor-alpha (P<0.01), and T-VOAS and Y-VOAS also showed a significantly inhibitory effect (P<0.05). Compared with the normal group, 14 endogenous metabolite biomarkers showed metabolic disturbance in plasma (P<0.05 or P<0.01). Compared with acute inflammation model group, C-VOAS and J-VOAS could better recover the levels of the endogenous metabolites (P<0.05 or P<0.01) than T-VOAS and Y-VOAS (P<0.05 or P<0.01). This study suggests that C-VOAS and J-VOAS show a better anti-inflammatory effect than T-VOAS and Y-VOAS. Therefore, the metabolomic method could be used to expound the anti-inflammatory mechanism of volatile oils from different processed products of AS, and provide a theoretical basis for clinical application of VOAS.
