Percentage of apoptosis induced by peniocerol or macdougallin in MCF-7 cell line.

Treatment	Percentage of apoptosis (%)
(A) Control, MCF-7, 48 h	11 ± 3% (EA)
	0.36 ± 0.15 (LA)
(B) Peniocerol 40 μM, 48 h	83 ± 2% (EA)
	0.23 ± 0.12 (LA)
(C) Macdougallin 40 μM, 48 h	66 ± 3% (EA)
	1.27 ± 6% (LA)

EA: early apoptosis, LA: late apoptosis.
Values are expressed as mean ± S.D. of three independent experiments, each performed in triplicate ().
