ABSTRACT
A new lignanamide (1), lyciumamide K, together with four known analogues (2-5), was isolated from the root of Lycium yunnanense Kuang. Based on HR-ESI-MS, NMR spectral data and quantum chemistry ECD calculations, the structure of this new compound was confirmed, including its absolute configuration. Evaluation of the antioxidant activity of compounds 1-5 in the oxygen radical absorption capacity (ORAC) assay showed that they all exhibited significant antioxidant activities. Particularly, compound 1 showed the best activity with ORAC values (U/mol) of 7.90 ± 0.52. Thus, the new lignanamide may be a good source of bioavtive and protective compounds.
