title: [Antitumor activity of the root of Euphorbia helioscopic in vitro].
abstract: Antitumor activity of the aquatic extract the root of Euphorbia helioscopia L (EWE) in Vitro were studied. Viable cells count, MTT staining and colonal formation assays of three kinds of cancer cells were used to assess the antitumor activity. Determined by viable cells count, the IC50 values of EWE against 7721, Hela, MKN-45 cells were 1.26, 1.98, 1.72 mg/ml respectively (72 h). Determined MTT staining, the IC50 values EWE against 7721, Hela, MKN-45 cells were 1.43, 1.67, 0.97 mg/ml. Determined by colonal formation, the inhibition rate of EWE (4 mg/ml) against 7721, Hela, MKN-45 cells were 59.8%, 66.4%, 70.5%. The results indicated that EWE had obvious antitumor activity.
