- Two new neolignans, patrineolignan A (1) and patrineolignan B (2), together with seven known lignans, were isolated from the 90 % aqueous EtOH extract of the roots of Patrinia scabra. Their structures were elucidated on the basis of spectroscopic data (HRESIMS, IR, 1D and 2D NMR) and comparison with literature data. The two new neolignans were evaluated in vitro for cytotoxic properties against human cervical carcinoma HeLa cell line and gastric carcinoma MNK-45 cell line using the microculture tetrazolium assay, and both 1 and 2 exhibited strongly cytotoxic activity against the two tumor cell lines.
