Figure 2
Effect of various plant extracts on the proliferation of U251. compared with the control or PBS group. There is concentration-dependent inhibition by administration of the extracts 48 h after treatment on U251 cell lines. Significant () antiproliferation is observed from 10 μg/ml in by all extracts except P. polyandra which is at 100 μg/ml. PBS was used in S. longepedunculata, and DMSO (:1000) was used in all other extracts.
