Fig. 3From: 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 cellsEffect of the crude MeOH C. nutans leaf extract on the D24 melanoma cells. Representative apoptosis profile plots of the untreated and treated cells after 24 or 72 h exposure to 1 or 2 mg/mL of the extract (a). The percentage of viable (b1), early apoptotic and late apoptotic/necrotic (b2) cell populations of untreated and treated groups. Data represents mean ± SD from three independent experiments (n = 3). * p ≤ 0.05, significantly different from control. †p ≤ 0.05, significantly different between treatment timesBack to article page
