The secretion profiles of pro-inflammatory parameters, including nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were found to be significantly reduced in 10-80 μg/ml dose ranges of n-hexane fraction (BP-H) from methanol extract of B. papyrifera stem bark. The expressions of inducible NO synthase (iNOS) was also significantly inhibited by BP-H. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that BP-H treatment decreased LPS-induced iNOS mRNA expression in RAW 264.7 cells.
