Abstract

Cirsium japonicum (CJ) leaf (L) alcoholic extracts were investigated for analysis their active components (flavonoids and flavanolignans; silymarins) and inhibitory effect on transforming growth factor (TGF)-${\beta}$ induced hepatic stellate cells (HSCs, LX-2 cells) activation. The CJ root (R) extracts were also analyzed and compared with leaf extracts. Total flavonoid and polyphenol contents of the leaf extracts showed higher than those of the root extracts. The content of each flavonoid compound, which was analyzed by HPLC, in CJ-L extracts was also higher than in CJ-R extracts. The results of flavanolignans content in CJ-L and CJ-R extracts were consistent in flavonoid and polyphenol. We studied inhibitory effect of two extracts against TGF-${\beta}1$ induced HSCs activation. The CJ-L extracts significantly suppressed overexpression of profibrogenic factor, ${\alpha}$-smooth muscle actin and collagen-${\alpha}1$(I). The CJ-R extract also showed inhibitory effect on TGF-${\beta}1$ induced HSCs activation, but the efficacy was lower than in CJ-L extract. These results suggest that CJ-L may contribute to the fibrotic liver treatment.
