Abstract

Ligusticum chuanxiong Hort is a famous health promoting plant cultivated in China, and widely consumed due to its various curative effects. To study the potential bioactive constituents from the rhizome of L. chuanxiong, a chemical investigation was thus performed. In present study, we report the isolation and identification of ten new compounds, including two Coumarins (1-2), four Lignans (3-6), and four Phenols (7-10), along with five known compounds (11-15) from the rhizome of L. chuanxiong. The structures of these compounds were unambiguously established by HR-ESI-MS, UV, IR, CD, NMR spectral data and comparison to reported data. Meanwhile, the anti-inflammation and hepatoprotective activities of all these compounds were evaluated. The results show that compounds 5, 6 and 7 showed excellent inhibition of NO production in LPS-induced RAW 264.7 cells stronger than curcumin, and compounds 5, 7 and 9 exhibited greater hepatoprotective effect than that of bicyclol.
