The present study explored the differences in active ingredients and in vitro anti-inflammatory effects of the decoction pieces by integrated processing(IPDP) and traditional processing(TPDP) of Polygoni Cuspidati Rhizoma et Radix(PCRER).The content of polydatin, resveratrol, emodin-8-O-β-D-glucoside, emodin, and physcion in IPDP and TPDP was determined by high-performance liquid chromatography(HPLC).The inflammation model was induced by lipopolysaccharide(LPS) in RAW264.7 cells.The mRNA levels of inflammatory cytokines tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), and interleukin-1β(IL-1β) in 60% ethanol extracts of IPDP and TPDP of different concentrations(5 and 10 μg·mL~(-1)) were determined by PCR.The results showed that the content of polydatin and emodin-8-O-β-D-glucoside in IPDP was significantly higher than that in TPDP, while the content of resveratrol, emodin, and physcion was higher in TPDP.The anti-inflammatory results showed that ethanol extracts of IPDP of different concentrations(5 and 10 μg·mL~(-1)) significantly inhibited the increase in the mRNA levels of IL-1β and TNF-α induced by LPS, whereas TPDP only had a significant inhibitory effect on IL-1β.This study preliminarily showed that the total content of five active ingredients in IPDP was higher than that in TPDP, and IPDP was superior to TPDP in anti-inflammatory activity in vitro, which provided an experimental basis for the production and application of IPDP.
