Abstract:

: Various mixtures were prepared depending on the mixing ratio ofhot water extract (SB-HW), andethanol extract (CM-E) and their anti-inflammatory activity were compared. Among them, SB-HW (80 μg/mL)/CM-E (120 μg/mL) or SB-HW (40 μg/mL)/CM-E (160 μg/mL) significantly inhibited LPS-stimulated NO and IL-6 levels in RAW 264.7 cells. The SB-HW (80 μg/mL)/CM-E (120 μg/mL) mixture, which was determined as active mixture, significantly reduced MUC5AC secretion in PMA and LPS-inducedNCI-H292 cells. The active mixture also reduced the production of PGEand IL-8 in PMA-induced A549 cells. LC-MS/MS analysis showed that the active mixture was composed of high contents of flavone glycosides, such as baicalin and cynaroside. Western blot analysis indicated that the active mixture suppressed phosphorylation of ERK, JNK, and p38, associating with the inhibition of MAPK signaling. Taken together, our results suggest that the active mixture could be applied as a new anti-inflammatory herbal medicine.
