The effects of a) cisplatin(CIS) (0-33.3 µM), and b) isolated compounds (0-100) from Echinophora cinerea on the viability of the PC-12 cells. The cell viability was determined by MTT assay after 24 hr exposure as described in materials and methods. Data are expressed as the mean±SEM of three separate experiments. **P-value <0.01, ***P-value<0.001 vs Control
