Abstract
Two new tetralin compounds were isolated from the aerial parts of Panicum turgidum Forssk. Their structures were elucidated by comprehensive 1 D and 2 D NMR experiments as well as high resolution ESI mass spectrometry. In addition, these two compounds have been tested for in vitro cytotoxicity against SKOV3 (Ovarian Carcinoma) and BT-549 (Breast Carcinoma). Compound 1 showed good cytotoxic activities against SKOV3 and BT 549 with IC50 value of 5.65 +/- 0.31 and 10.3 +/- 0.56 mu g/mL, respectively
