Fig. 1From: Comparison of cytotoxicity between extracts of Clinacanthus nutans (Burm. f.) Lindau leaves from different locations and the induction of apoptosis by the crude methanol leaf extract in D24 human melanoma cellsCytotoxic effect of the crude MeOH C. nutans leaf extract on the D24 melanoma and NHDF cells. The cells were treated with different concentrations (0–2 mg/mL) of the extract for 24 and 72 h. Data represents mean ± SD from two independent experiments (n = 2). * p ≤ 0.05, significantly different from vehicle control (<0.1 % DMSO). †p ≤ 0.05, significantly different between treatment timesBack to article page
