From: Antiangiogenesis and antioxidant activity of ethanol extracts of Pithecellobium jiringa
Effect of P. jiringa fruit rinds extracts on clonogenicity of HUVEC cells. (A) Effect of EtOH extract and EW extract. (B) The clonogenicity of the cells in 6-well plates after treatment with the extracts and controls. The clonogenic cell survival of HUVEC cells treated with: (−) 1% DMSO as negative control, (+) betulinic acid 20 μg/ml as positive control and indicated concentrations of the extracts (μg/ml). Values are means of two experiments, error bars equal ± SD. Plating efficiency was 13.7 ± 1.00%. *P < 0.05, **P < 0.01 and ***P < 0.001, comparing to control.
