Valeriana wallichii.). Their structures were elucidated by extensive spectroscopic analysis, especially 2D NMR and ESI-MS/MSn. All isolated compounds displayed moderate cytotoxicity against the lung adenocarcinoma (A549), metastatic prostate cancer (PC-3 M), colon cancer (HCT-8), and hepatoma (Bel7402) cell lines with IC50 values of 2.8-8.3 μM.
