Sažetak
Phytochemical investigation of the rhizome of Ligusticum chuanxiong Hort led to the isolation and identification of three new compounds, chuanxiongoside A, (2E,4E)-8-(6-O-inositolyl)-8-oxo-2,7-dimethyl-octadienoic acid (2), chuanxiongoside C (3). The structures of these compounds were unambiguously established by HR-ESI-MS, UV, IR, CD, NMR spectral data and comparison to reported data. All the isolated compounds (1-3) were investigated for their inhibitory effects on nitric oxide (NO) production in LPS-induced RAW 264.7 cells. All compounds showed excellent inhibition of NO production stronger than curcumin. [Formula: see text].
