Abstract:
Chemical investigation of the edible roots of Codonopsis pilosula yielded a new lignan (1), together with twenty-nine known compounds, including twenty-one lignans (2-22) and eight phenylpropanoids (23-30). The structure of the new lignan, including its absolute configuration, was determined using a combination of extensive spectroscopic analysis, NMR and ECD calculations, and comparison with literature values. The isolated lignans and phenylpropanoids (excluding 1, 20, 21 and 28) were evaluated for their antioxidant activities using ABTS and DPPH radical scavenging assays. Among them, compounds 2-6, 18 and 23 exhibited strong scavenging activities in ABTS and DPPH assays with SC50 values ranging from 9.73 to 47.26 μM compared with the positive control L-ascorbic acid.
